During the tenure of this assignment, help, co-operation and assistance have been obtained from
a large number of individuals, government departments, local bodies, para-statal agencies, social
workers, representatives of NGOs and CBOs. They have provided their valuable time and
suggestions to members of the PPTA team to assist in this study. It is rather difficult to thank them
individually. We express our sincere thanks to all those people collectively.
Their support, encouragement and insights into the social, economic, environmental and
infrastructure problems of the study area and the sector as a whole have provided an essential
input into the proposals in the report. More often than not, these suggestions triggered useful
discussions in shaping various projects in project towns of Bhagalpur, Darbhanga, Gaya and
Muzzaffarpur for infrastructure improvement.
In addition to the obviously critical technical support by the Asian Development Bank, preparation
of this Report was made possible through the enthusiastic support and guidance of Shri Girish
Shankar, Principal Secretary (up to February 2011) and Shri D K Shukla, Special Secretary of the
Urban Development and Housing Department, Government of Bihar and the Mayors, Municipal
Commissioners and their enthusiastic staff in the preparation of this PPTA report. At the very
pragmatic level, Mr. Hiroyuki Ikemoto, the ADB Urban Development Economist, continues the
challenge of supporting the consulting team and their enormous requests. Our thanks are also due
to Shri Shashi Shekhar Sharma who guided the completion of this final report upon taking over as
Principal Secretary from February 2011.
Unknown to them, but the daily observation of all residents, their situations and their needs
contributes the most to the exercise, and will be thanked by successfully contributing this project's
results to their future.

EXECUTIVE SUMMARY
1. Bihar Urban Development Investment Programme (BUDIP) is intended to optimize social and economic development in 4 selected towns/cities in the State under Phase I, particularly district headquarters with significant development potential. BUDIP Phase I will be implemented over a seven year period beginning in 2011, and being funded by a Multitranche Financing Facility (MFF) loan from the Asian Development Bank (ADB). The Executing Agency is the Urban Development & Housing Department (UDHD) of the Government of Bihar; and the Implementing Agency is the BUIDCO Programme Management Unit (PMU) of the Bihar Urban Development Investment Programme (BUDIP). ADB requires the consideration of environmental issues in all aspects of the Bank‘s operations, and the requirements for Environmental Assessment are described in ADB‘s SPS (2009). This states that ADB requires environmental assessment of all project loans, program loans, sector loans, sector development program loans, loans involving financial intermediaries, and private sector loans.
2. This Initial Environmental Examination (IEE) has been prepared for the Muzaffarpur Sewerage and Sanitation Subproject as part of BUDIP Tranche 1. The subproject covers (i) construction of a sewage treatment plan (STP), (ii) laying of trunk mains sewer pipes, (iii) laying of sub-mains and laterals, (iv) laying of pumping main, and (v) construction of pumping stations. The subproject is needed due to lack of integrated sewerage and sanitary system in Muzaffarpur resulting to unsanitary conditions prevailing in the town. Wastewater commonly overflows to the drainage system, which is under-designed and not maintained, causing unhygienic and odorous pools forming on roads and other depressions. The groundwater table is also likely to be contaminated due to seepage of wastewater through leaky and broken water supply pipe lines.
3. Detailed design will be begin under PPTA in the month of March 2011 and expected to be completed in June 2011. Implementation will be started from 2012 and likely to be completed by middle of 2014.
4. The subproject sites (sewer lines and STP) are located in Khabara Village, outside municipal area of Muzaffarpur town. The subproject sites are generally flat. The subproject sites are not located in areas prone to water-logging, salinasation, flash flood. There are no protected areas, wetlands, mangroves, or estuaries in the subproject sites. Trees, vegetation (mostly shrubs and grasses), and animals are those commonly found in urban areas. The subproject sites are not located in or near any historically-, culturally-, archaeologically- or architecturally-significant or tourists area. There is no settlement within 500 m of the STP site except one household, noted within 250 m of the proposed STP location.
5. After treatment treated water after conforming the standard will be discharged to Furdoo nala passing nearby the proposed STP location and partly will be released to agricultural land (specifically during summer period) as a source of irrigation water.
6. Availability of environmentally-suitable lands for an STP is very limited in Muzaffarpur. The present site has been considered because it is located in an area of: (i) at least 500 m from any inhabited areas; (ii) no risk of flooding or other hazards that might impair the functioning of the plant; (iii) no risk of chance finds; (iv) no waterway that is a source of water for domestic or municipal supply; and (v) available right-of-way for the sewer network.
7. No potential impacts were identified as being due to the subproject design but were identified in relation to construction and operation of the infrastructure. Mitigation measures have been developed to reduce all negative impacts to acceptable levels. An Environmental Management Plan (EMP) is proposed as part of this IEE which includes (i) mitigation measures for significant environmental impacts during implementation, (ii) environmental monitoring program, and the responsible entities for mitigation, monitoring, and reporting; (iii) public consultation and information disclosure; and grievance redress mechanism. Mitigation measures have been developed to reduce all negative impacts to acceptable levels. A number of impacts and their significance have already been reduced by amending the designs.
vii Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation
8. During the construction phase, impacts mainly arise from the need to dispose of large quantities of waste soil and import a similar amount of sand to support the sewer pipes in the trenches; and from the disturbance of residents, businesses, traffic and important buildings by the construction work. These are common impacts of construction in urban areas, and there are well developed methods for mitigation.
9. The use of asbestos cement (AC) pipes in the existing water distribution network presents a particular risk to workers and the public if disturbed, as inhalation of asbestos dust, which is carcinogenic. These systems will not be disturbed under the project and kept in place. Moreover, special measures were developed to protect workers and the public from exposure to carcinogenic asbestos fibres in the event that AC pipes used in the existing water supply system are uncovered accidentally during excavation work.
10. Specific measures have been developed to avoid damaging important remains in case of chance archaeological finds during excavation work.
11. The project will employ persons from the local workforce who live in the vicinity of construction sites to provide them with a short-term economic gain; and ensure that people employed in the longer term to maintain and operate the new facilities are residents of nearby communities.
12. Once the system is operating, most facilities (STP, sewer network, pump house) will operate with routine maintenance. Leaks in the sewer network will be monitored and repaired. It will also be conducted in areas that have already been excavated, so there will be no need to protect archaeological material.
13. The main impacts of the operating water supply system will be beneficial as the citizens of Muzaffarpur will be provided with an underground sewage system, which will serve a greater proportion of the population, including slum-dwellers. This will improve the quality of life of people as well as benefiting both individual and public health as the improvements in hygiene will reduce the incidence of disease associated with poor sanitation.
14. Mitigation will be assured by a program of environmental monitoring to be conducted during construction and operation to ensure that all measures are implemented, and to determine whether the environment is protected as intended. Corrective measures to be taken as necessary. This will include observations on- and off-site, document checks, and interviews with workers and beneficiaries, and any requirements for remedial action will be reported to the Investment Project Management Unit (PMU). There will also be longer-term surveys to monitor the expected improvements in the quality of discharged treated effluent and the health of the vicinity of the project area.
15. The stakeholders were involved in developing the IEE through face-to-face discussions on site and a large public meeting held in the town, after which views expressed were incorporated into the IEE and the planning and development of the project. The IEE will be made available at public locations in the town and will be disclosed to a wider audience via the ADB website. The consultation process will be continued and expanded during project implementation by a nationally-recognized NGO appointed to handle this key element and to ensure stakeholders are fully engaged in the project and have the opportunity to participate in its development and implementation.
16. The subproject is unlikely to cause significant adverse impacts. The potential adverse impacts that are associated with design, construction, and operation can be mitigated to standard levels without difficulty through proper engineering design and the incorporation or application of recommended mitigation measures and procedures. Based on the findings of the IEE, the classification of the Project as Category ―B‖ is confirmed, and no further special study or detailed EIA needs to be undertaken.

1 Introduction
1.1 Purpose of the Report
Bihar Urban Development Investment Programme (BUDIP) is intended to optimize social
and economic development in 4 selected towns/cities in the State, particularly district
headquarters with significant development potential. This will be achieved through
investments in urban infrastructure (water supply; sewerage and sanitation; solid waste
management; and urban storm water drainage). The assistance will be based on the
State-level framework for urban reforms, and institutional and governance reforms
recommended by the Government of India through the Jawaharlal Nehru National Urban
Renewal Mission (JNNURM) and Urban Infrastructure Development Scheme for Small
and Medium Towns (UIDSSMT).
BUDIP will be implemented over a seven year period beginning in 2011, and being funded
by a loan via the Multitranche Financing Facility (MFF) of Asian Development Bank (ADB).
The Executing Agency is the Urban Development & Housing Department (UDHD) of the
Government of Bihar; and the Implementing Agency is the BUIDCO Programme
Management Unit (PMU) of the Bihar Urban Development Investment Programme
(BUDIP).
This Initial Environmental Examination (IEE) has been prepared for the Muzaffarpur Waste
water Subproject as part of BUDIP. The subproject covers (i) construction of a sewage
treatment plan (STP); (ii) laying of trunk mains sewer pipes, (iii) laying of sub-mains and
laterals, (iv) laying of pumping main, and (v) construction of a pumping station.
This IEE report covers the general environmental profile of Muzaffarpur and includes an
overview of the potential environmental impacts and their magnitude on physical,
ecological, economic, and social and cultural resources within the subproject‘s influence
area during design, construction, and operation stages. An Environmental Management
Plan (EMP) is also proposed as part of this report which includes mitigation measures for
significant environmental impacts during implementation of the Project, environmental
monitoring program, and the responsible entities for mitigation and monitoring.
1.2 Extent of the IEE Study
This IEE report was prepared on the basis of detailed screening and analysis of all
environmental parameters, field investigations and stakeholder consultations to meet the
requirements for environmental assessment process and documentation per ADB‘s
Safeguard Policy Statement (SPS, 2009) and Government of India Environmental Impact
Assessment (EIA) Notification of 2006.
1.2.1 ADB Policy
ADB requires the consideration of environmental issues in all aspects of ADB‘s operations,
and the requirements for Environmental Assessment are described in ADB SPS 2009.
This states that ADB requires environmental assessment of all project loans, program
loans, sector loans, sector development program loans, loans involving financial
intermediaries, and private sector loans.
Screening and Categorization. The nature of the environmental assessment required for
a project depends on the significance of its environmental impacts, which are related to
the type and location of the project, the sensitivity, scale, nature and magnitude of its
potential impacts, and the availability of cost-effective mitigation measures. Projects are
screened for their expected environmental impact are assigned to one of the following four
categories:
(i) Category A. Projects could have significant adverse environmental impacts. An EIA is required to address significant impacts.
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 2
(ii) Category B. Projects could have some adverse environmental impacts, but of lesser degree or significance than those in category A. An IEE is required to determine whether significant environmental impacts warranting an EIA are likely. If an EIA is not needed, the IEE is regarded as the final environmental assessment report.
(iii) Category C. Projects are unlikely to have adverse environmental impacts. No EIA or IEE is required, although environmental implications are reviewed.
(iv) Category FI. Projects involve a credit line through a financial intermediary or an equity investment in a financial intermediary. The financial intermediary must apply an environmental management system, unless all Projects will result in insignificant impacts
Environmental Management Plan. An EMP which addresses the potential impacts and
risks identified by the environmental assessment shall be prepared. The level of detail and
complexity of the EMP and the priority of the identified measures and actions will be
commensurate with the Project‘s impact and risks.
Public Disclosure. ADB will post the following safeguard documents on its website so
affected people, other stakeholders, and the general public can provide meaningful inputs
into the project design and implementation:
(i) For environmental category A projects, draft EIA report at least 120 days before Board consideration;
(ii) Final or updated EIA and/or IEE upon receipt; and
(iii) Environmental Monitoring Reports submitted by Project Implementation Unit during project implementation upon receipt.
1.2.2 National Law
The Government of India EIA Notification of 2006 (replacing the EIA Notification of 1994),
sets out the requirement for environmental assessment in India. This states that
Environmental Clearance is required for specified activities/projects, and this must be
obtained before any construction work or land preparation (except land acquisition) may
commence. Projects are categorised as A or B depending on the scale of the project and
the nature of its impacts.
Categories A projects require Environmental Clearance from the National Ministry of
Environment and Forests (MOEF). The proponent is required to provide preliminary details
of the project in the form of a Notification, after which an Expert Appraisal Committee
(EAC) of the MOEF prepares comprehensive Terms of Reference (TOR) for the EIA study,
which are finalized within 60 days. On completion of the study and review of the report by
the EAC, MOEF considers the recommendation of the EAC and provides the
Environmental Clearance if appropriate.
Category B projects require environmental clearance from the State Environment Impact
Assessment Authority (SEIAA). The State level EAC categorises the project as either B1
(requiring EIA study) or B2 (no EIA study), and prepares TOR for B1 projects within 60
days. On completion of the study and review of the report by the EAC, the SEIAA issues
the Environmental Clearance based on the EAC recommendation. The Notification also
provides that any project or activity classified as category B will be treated as category A if
it is located in whole or in part within 10 km from the boundary of protected areas, notified
areas or inter-state or international boundaries.
The only type of infrastructure provided by the BUDIP that is specified in the EIA
Notification is solid waste management, where EC is required for all Common Municipal
Solid Waste Management Facilities (facilities that are shared by more than one town).

Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 3
1.2.3 Others
Actions required for establishment of the STP in Muzaffarpur (Table 2 of the
Environmental Assessment Resettlement Framework [EARF]) includes obtaining from
Bihar State Pollution Control Board (BSPCB) (i) Consent for Establishment (CFE) before
construction; and (ii) Consent for Operation (CFO) after construction prior to operation of
the sewage treatment plant. In order to apply for the CFE, the land is to be acquired and
receipt of a land allotment letter is to be submitted as part of the application.
2 Description of the Project
2.1 Type, Category and Need
Type. This is an urban sewerage subproject intended to improve the current environment
in Muzaffarpur. This is one of a series of subprojects designed by the BUDIP that are
intended to raise the standards of the municipal infrastructure and services of Muzaffarpur
town and the other urban centres to those expected of modern Asian towns. Location of
Muzaffarpur district is shown in Figure 1.
District map of Muzaffarpur and Municipal area of Muzaffarpur town is shown in Figure 2
and 3 respectively.
Category. Environmental examination indicates the proposed subproject falls within
ADB‘s environmental Category B projects. The Project components will only have small-
scale, localized impacts on the environment, and can be mitigated. Under ADB procedures
such projects require an IEE to identify and mitigate the impacts, and to determine
whether further study or a more detailed EIA may be required.
Need. For a town/city with present population density of almost 150 persons per ha and a
projected population density of more than 200 persons per ha by 2026, it is not
economically viable to provide onsite sewage treatment and disposal systems, like the
septic tank with the soak pit, to individual households. This will cost Rs. 3,500 per capita,
which is higher than the cost of providing sewerage system with sewage treatment plant.
However, in some areas with low population densities, the onsite sanitation system can be
considered as an alternative. Also for improvement of hygienic condition of the town/city
underground sewerage system is needed.
2.2 Location and Implementation Schedule
The subproject is located in Muzaffarpur town of Muzaffarpur District, in the eastern part of
Bihar in eastern India. The proposed infrastructures will be located in and around the town.
The STP site is located in village Khabara, about 3 km from Muzaffarpur town. The
present site has been considered because it is located in an area of: (i) at least 500 m
from any inhabited areas (except single household located within 250-300 m); (ii) no risk of
flooding or other hazards that might impair the functioning of the plant; (iii) no risk of
chance finds; (iv) no waterway that is a source of water for domestic or municipal supply;
and (v) available right-of-way for the sewer network.
Detailed design will begin in the month of March/April 2011 and will be completed by July
2011. Implementation will be started in the year 2012 and likely to be completed by end of
2014.

There is no organized sewer network in the Project Area at present. The existing storm
water drains serve as the sewage collection system. During the dry season these drains
carry only dry weather flow and during monsoon a combined flow of sewerage and storm
water runoff. Due to inadequate capacity of these storm water drains flooding occur during
events of heavy rains and the sewage mixed storm water overflows the drains.
A considerable number of individual houses (80% of the total households) have
constructed septic tank. Around 15% population is served by low cost sanitation and dry
latrines. Existence of onsite disposal systems like soak pits are mostly absent. The septic
tank effluent and sullage from the premises is discharged to adjacent storm water drains.
2.3.2 Proposed Sewerage System
A preliminary sewer network alignment has been prepared based on the very approximate
levels. Following the land availability a piece of land has been identified for STP in the
North Eastern fringe of the Municipality, at a distance of about 2 km from the boundary of
municipality.
The Project Area is divided into 9 smaller sewerage zones mainly depending on the
topography. For each sewerage zone, an outline estimate of the total lengths of primary
and secondary sewers is obtained by identifying the major roads.
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 6
Total Road Length km 300
Proposed Coverage (90%) km 270
Primary/Trunk Sewer (300-1400 mm dia) km 47.5
Secondary sewer (250-355 mm dia) km 54.5
Tertiary sewer (160 -250 mm dia) km 168
The proposed sewerage system includes 9 intermediate pumping stations and a main
pumping station (MPS) before the STP. Each of the intermediate pumping station will
serve a specific sewerage zone and will discharge the wastewater to the gravity sewer of
the adjacent sewerage zone. The MPS will discharge the total flow to the inlet of STP.
Land requirement for the pumping station will vary depending on the size of wet well.
However, for preliminary design purpose, an average area of 600 m2
has been considered
for each pumping stations. Thus the land requirement for the proposed nine intermediate
PS will be 0.54 ha 0.6 ha.
The sewage treatment plant will be developed in two phases. The plant will be based on
the Extended Aeration variant of Activated Sludge process. The capacity of the STP for
the two phases and the land requirement is indicated below.
Year Capacity Land Requirement*

2026 43 5.5
2041 72 8.0
*Including Land for MPS and buffer zone
The land requirement for the STP will be around 8 ha including the main pumping station
and buffer zone. A piece of private land has been identified outside the municipal
boundary in the Khabara Village. The location of the identified piece of land is 1.42 km in
the Southern direction, from the junction of the NH28 and the Khabara road near the Shiv
Chowk, immediately before the bridge over the Furdoo nala. Land is available on both
sides of the Khabara road. The piece of land on the right hand side of the road, facing the
nala, has been selected. It is free from all obstructions. Presently it is used for agricultural
purpose. There is no human settlement in the identified land but acquisition of private land
is required for implementation of the project.

3 Description of the Environment
3.1 Physical Resources
3.1.1 Administrative Boundaries
Muzaffarpur Municipal area comes under the Musahari block. The block has 117 villages
and only one urban centre, i.e. Muzaffarpur. In the year 1864, Muzaffarpur was declared
as Municipality, which was upgraded later in 1981 as Municipal Corporation. The first
elected body of the Municipal Corporation was constituted in the year 2002 which is
functional till date. The Muzaffarpur Municipal Corporation (MMC) is surrounded by River
Budhi Gandak on north, Dighra Rampur Sah village on south, the National Highway (NH)
57 and railway line on west and extends upto reserve police station on eastern limit. The
area of Muzaffarpur Municipal Corporation is approximately 26.68 km2 and is divided into
49 wards in 2007. The Muzaffarpur Municipal area had a total population of 3, 05,525 and
was divided into 32 wards as per Census 2001. However, the ward boundaries have
recently been revised and currently the town has 49 wards.
3.1.2 Topography, Drainage, and Natural Hazards
Topography. Muzaffarpur district is situated in the nearly rectangular North Gangetic
alluvial plane in North Bihar. The slightly saucer shaped town with a low lying central part
is on the left Bank of Burhi Gandak river. As part of the Burhi Gandak sub basin, the town
is built by the Himalayan silt and sand, brought by the glacier and rain fed meandering
rivers Gandak and Burhi Gandak. The physical environment of a region is a direct result of
the geologic history, the resulting landforms and the processes of nature, which shape the
terrain. Being situated on the Gangetic alluvial plain, Muzaffarpur is more or less flat. The
average altitude of the town is approximately 56 m above the mean sea level (MSL). The
general slope of the town is towards south. However, low lying areas, which remain water
logged during rainy season, are found along Budhi Gandak River in the north. The
average ground level varies from 53 m to 58 m from MSL.
Drainage. The land slopes gently southward and the area are well drained by rivers
flowing from North and North-Western directions. The main rivers of the area are Buri
Gandak with their distributaries and moribund channels. These are basically perennial
meandering rivers and these with the man made water bodies from the drainage network
of the area.
Natural Hazards. The area being close to seismically active Himalaya is prone to seismic
hazard. As per the Seismic Zoning Map of India (IS: 1893-2002), Indian Sub-continent is
divided into four zones named II, III, IV and V. The area under investigation falls under
Zone-IV of the Seismic Zonation Map of India (see Figure 6 below) prepared by the
Bureau of Indian Standards. With reference to the MSK intensity scale used for all
engineering design purposes, the region lies in the high to moderate damages risk zone.
The Global Seismic Hazard Assessment Program (GSHAP) seismic hazard map of Bihar
(Figure 7) reveals that the area lies in the moderate hazard zone.
Bihar is vulnerable to different kinds of disaster such as flood, cyclone and earthquake due
to its geographical and topographical location. Figure 8 shows the environmental sensitive
area of Muzaffarpur. Vulnerability of Muzaffarpur district / Muzaffarpur Municipal Area can
be estimated form the following facts:
▪ The earthquake hazard map of Bihar shows that Muzaffarpur district falls in Seismic
Zone IV, which is a high damage risk zone and an earthquake up to a magnitude of
8.0 on Richter scale has the potential to hit the area. Thus Muzaffarpur Municipal
Area is an earthquake hazard prone area and falls in high damage risk zone.
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 11
▪ The wind hazard map of Bihar, shows that Muzaffarpur district falls in High damage
risk zone with cyclonic wind velocities around 47m/s. Thus Muzaffarpur Municipal
Area is a wind hazard prone area and falls under High damage risk zone.
▪ The flood hazard map of Bihar (Figure 9) shows that most of the parts of the
Muzaffarpur district are susceptible to flooding. The Muzaffarpur Municipal Area
falls almost entirely in flood susceptible risk zone.
It is evident that Muzaffarpur town located in Muzaffarpur district is susceptible to natural
hazards with high risk or probability of occurrence of a high intensity earthquake, cyclone
and also flooding. Natural calamities result in recurring losses and eats into the hard
earned developmental gains. Since most of the natural disasters are barely predictable
and almost non-preventable, a state of preparedness and ability to respond quickly to a
natural calamity is probably the only way to mitigate loss of life and property and the
human suffering.
The knowledge of the physical nature of earthquakes and their influences on engineering
structure is essential for working in the zones where the occurrence of earthquake is
probable.

3.1.3 Geology, Geomorphology, Mineral Resources, and Soils
Geology. The proposed road runs through an alluvial terrain underlain by unlithified soft
quaternary formations, which can be divided into three districts morpho- stratigraphic units:
o Hajipur / Madhubani Formation: It is the oldest Quaternary unit in the area encountered in the southwest of Muzaffarpur town where it forms high level alluvial terraces. It is characterized by yellowish brown and brownish grey clayey material impregnated with ‗Caliche‘ nodules formed in-situ due to weathering under semi-arid condition. The unit supports habitats and cultivation.
o Jaynagar / Vaishali Formation: This dominant formation of the region includes the older flood deposits of Burhi Gandak and Bagmati river systems. The unconsolidated sediments comprising alternating sequences of sand, silt and clay are fine in texture, grey in colour do not contain ‗Caliche‘ nodules and are unoxidised. The unit is widely used for cultivation and human settlements.
o Diara Formation: It includes the unconsolidated flood plain deposits of the present day rivers and is confined to the meander belts of the main river channels. This unit comprises fine sand and silt with occasional layers of clay. It contains flakes of muscovite and biotite with minor amount of dark coloured minerals. Temporary settlements and seasonal cultivation are the preferred land-uses.
Geomorphology. The town is located on the alluvial deposition underlain by unlithified
soft quaternary formations. According to lithostratigraphic characterization, the alluvial
deposition of the Muzaffarpur town belongs Newer Alluvial Group or Khadar.
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 14
Mineral Resources. Presence of Mica is reported in Muzaffarpur. The STP site is not
located nearby any mineral resources area.
Soils. The soil of a major part of Muzaffarpur district is calcareous in nature containing
upto 40% free calcium carbonate, and only few blocks on its eastern edge have non-
calcareous deposits. Due to canal irrigation and construction, the natural drainage of this
area has been disturbed resulting in rise in water table and ultimately developing salinity in
scattered patches on vast stretch of land. A separate class of soil as per taxonomy has
also come into existence. The non-calcareous soils are whitish, pale yellow to olive in
colour, neutral to moderately alkaline in reaction, of medium light to medium heavy in
texture on surface and underlain by medium to heavy textured soils.
i. The entire road section lies on alluvial plain underlying by unconsolidated formation of Quaternary to Archaean period. The soils of the area have been developed on alluvial deposits transported mainly by sub-Himalayan rivers.
ii. There are two major group present in this area – Entisols and Inceptisols. Entisols are subdivided into younger alluvial soils (Udifluvents) and Bhabar soils (Ustorthents). But, Udifluvents is the main dominant soil group in this area. This soil is deficient in nitrogen, phosphoric acid and humus. Texturally these are sand to loamy sand with pH value on the alkaline side. Among the Inceptisols – Ustochrepts and Haplaquepts (calcareous alluvial soil) are the main dominant soil group present in this area. The pH value of the soil is on the alkaline side and contents available phosphoric acid and potash in the lower side.
3.1.4 Climate
The project area experiences a tropical monsoon type of climate with distinguishable
seasonal differences in ambient temperature, relative humidity, rainfall and direction of
wind. Typically the area witnesses four seasons which can be broadly described as-
Winter -December to February - Cool dry; Summer ( pre- monsoon) - March to May - Hot
Dry; Monsoon - June to September - Hot Wet and Post monsoon - October to November –
Transitional.
The climate in the cold weather is pleasant. The days are bright and warm and the sun is
not too hot. As soon as the sun sets, the temperature falls and the heat of the day yields
place to a sharp bracing cold. The mean temperature in November all over the area varies
from 19oC to 20oC. The mean temperature in December is 16oC. January is the coldest
month and the mean minimum temperature varies from 7oC to 10oC though some places
record much lower temperatures than 6oC. The highest temperature is often registered in
May which is the hottest month in the area.
The average relative humidity is always greater in the morning and is usually more than
70% except in high summer (April-May). The post monsoon and the winter seasons are
calm period; the average wind speed does not exceed 5 km/h even during the monsoons.
The wind direction is predominantly easterly during monsoon and westerly in the winter.
The annual average rainfall of the Muzaffarpur is around 1200 mm. The annual average
rainfall for a period from 1997 to 2007 shows sufficient variation (600 mm in 2006 to 2480
mm in 2007). Annual average rainfall of the town is presented in Table 2.

5. Air Quality
There is no data on ambient air quality of Muzaffarpur town, which is not subject to
monitoring by the BSPCB as there are no major industries. Traffic is the only significant
pollutant in Muzaffarpur, so levels of oxides of sulphur and nitrogen are likely to be well
within the National Ambient Air Quality Standards (NAAQS).
6. Surface Water
The major drainage channels of the Muzaffarpur town are Burhi Gandak River in the North
and North East and Furdoo nala at the West. Burhi Gandak River finally meets the
Ganges near Khagwara. It is believed that river Gandak has migrated westward from the
position of the present-day Burhi Gandak to its present course on the west in course of
last several hundred years. In this process of shifting, it has created numerous chaurs
(saucer like depressions) and mauns (deep horseshoe shaped water bodies formed due to
avulsions/cut-offs) in the Basin. Burhi Gandak River itself has been changing its course
locally through minor avulsion. The evidence is the old course of Burhi Gandak in the
North East of the Project Area. Both Gandak and Burhi Gandak rivers are now more or
less stabilized. Burhi Gandak has Himalayan origin and considerable portion of its
catchments lie in the glacial region. It is therefore, snow-fed and perennial in flow. These
rivers have catchments in the Himalayan region in Nepal. Furdoo nala is flowing almost
parallel to the western boundary of the Town in the North to South Direction. It was
originally connected to river Gandak and now heavily silted up and discharges into a
marshy land crossing NH 77.
The surface water sources in the project area are generally perennial. There is no fixed
water quality monitoring station for Buri Gandak River. However in the year 2009
monitoring has been carried out for Buri Gandak river at Muzaffarpur,. The results are
shown in Table 3.

7. Geohydrology and Groundwater
The area is occupied by the thick pile of unconsolidated sediments laid down by the
Ganga and its northern bank tributaries. Fairly thick regionally extensive confined / un-
confined aquifers down to depth 300 m as well as moderately thick but discontinuous
confined and unconfined aquifers present in this region. The thickness of sediment
increases from south to north. These unconsolidated sediments are made up of
alternations of sand clay with individual sand and clay layers showing interfingering
relationship.
In parts of Muzaffarpur district the tube well within 100 m depth yields in the range of 100
to 150 m3/hr. The transmissivity value is high, around 15000 m2/day with storativity 2.1 x
10-3. The depth to water level in this region varies from 5 to 10 m below ground level
during Pre-monsoon and the same level is in the range of 2 to 5 m below ground level
during post-monsoon. The average water level fluctuation is 2 to 4 m.
Ground in this region generally contain high mineral as indicated by EC value in the range
of 1000 to 1500 µs/cm. The area is generally characterized by low to medium chloride
concentration (50 mg/L) and low nitrate levels.
3.2 Biological Resources
There is no ecologically sensitive area exist near project site. There is no wildlife
sanctuary, national park, biosphere reserve, tiger reserve or any other ecologically
sensitive area exist within 10 km of the project area.
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 17
After the division of the state, only 7% of the forest remains in Bihar. The population
pressure is the main cause of loss of forest cover. Bihar has monsoon type of forest. Due
to low forest cover the state is facing acute problem of rainfall. Social forestry has wide
scope in Bihar. The government has launched a programme to plant trees along the road,
open railway land and barren land. The forest area in project district is mentioned in Table
4 below.

District Geographical Area (Sq km) Forest Area (Sq km) Percentage of Forest
Muzaffarpur 3172.0 4.0 0.13
(Source: State of Environment Report, Bihar, 2007)
The study area is flat alluvial plain and most of the land under cultivation with very little
remains under natural vegetation.
Common Trees: Existence of trees is a natural phenomenon in the project area. The
different type of trees present in and around the project areas – Banyan (Ficus
bengalensis), Arjun (Terminalia arjuna), Tamarind (amarindus indica), Gulmohar
(Caesalpinia pulcherrima, Delonex regia), Sesham (Dalbergia sisoo), Simul (Bombax

3.3 Economic Development
Economic base of a town reflects its prosperity. Muzaffarpur town, being the district
headquarters, has been functioning as administrative center. The main economic base of
the town is trade and commerce. Muzaffarpur serves as market centre for nearby small
Bihar Urban Development Investment Programme

A majority of the land is used for residential purposes (57.43%), followed by area under
agriculture (10.31%), land put to public and semi-public use (8.81%), parks, open spaces
and recreational area (7.08%), industrial use (5.9%), roads (5.4%), water bodies (2.84%),
and area under commercial use (1.08%). About 1.15% land is lying vacant. The landuse
classification has been marked as per the guidelines of UDPFI.
The STP site is located in an agricultural area.
3.3.2 Commerce, Industry and Agriculture
Commerce. Muzaffarpur is famous for exporting Lichi. Long ago, the area was famous for
hand-woven textiles, sugar cane, indigo, opium and other products. The district has a few
sugar mills, which are now old and dilapidated. It is the commercial hub of North Bihar and
the wholesale market for Mumbai, Surat and Ahmedabad. Textile mills in the
famous Marwari community dominate Suta Patti. The commercial hub of the town is
Motijheel.Muzaffarpur is a major wholesale textile trading centre (third largest in the
country).
Industrials Development. There is an industrial area in the Southern Part of the
Municipality but most of the industries here are non functional. Existing industries are
mainly small scale ones like cottage and wood sawing industry, footwear manufacturing.
The major manufacturing industry in the Muzaffarpur town is the Bharat Wagon and
Engineering Ltd. for manufacturing of railways wagons. The STP site is not located in this
industrial area.
Agriculture. The area around Muzaffarpur is largely agricultural. The principal crops are
rice, wheat, pulses, jute, maize and oil seeds. Cauliflower, cabbage, tomato, radish, carrot,
beetroot, among others, are also grown. Rice and wheat account for most of the area
under cultivation. Maize is the next important crop for the district. Sugar cane, potato and
barley are some of the non-cereal crops grown. The district is famous for its delicious
mangoes, and its lychee, which are exported to other parts of the country and even
abroad.

3.3.3 Infrastructure
Water supply. At present the municipality is served by groundwater from 20 deep bore
wells (out of which 13 are functional) with a total yield of 3.6 MLD. The supply rate is
around 40 lpcd for duration of 13 hrs per day. Out of the total road length of 235 km the
distribution system covers only 72. Only 40% of households have a proper house
connection. Apart from the house connections, people are also served by 482 hand pumps
and 422 stand posts in the Town. Present water supply level is far below the stipulated
limit of 135 lpcd for a medium sized town like Muzaffarpur. A water supply scheme has
been approved under the central Government funded UIDSSMT scheme for augmentation
of the water supply system of the town at a cost of Rs. 980 million. This scheme has
considered 135 lpcd water supply for the projected population of 0.48 million in 2040. As
this scheme is based on only groundwater sources, which has a limited reserve, additional
schemes will be required to supplement this schemes in the longer run and to ensure a
supply of 135 lpcd of supply.
Sewerage and Sanitation. Muzaffarpur does not have any sewerage system. There is no
organized sewer network in the Project Area at present. The existing storm water drains
serve as the sewage collection system. During the dry season these drains carry only dry
weather flow and during monsoon a combined flow of sewerage and storm water runoff.
Due to inadequate capacity of these storm water drains flooding occur during events of
heavy rains and the sewage mixed storm water overflows the drains.. At household level
individual septic tanks are provided to handle domestic sewage. As per the status report
on integrated development project for Muzaffarpur, the total sewerage generation in 2007
is 39.15 MLD.
Drainage. Storm water drainage is a critical problem of the Muzaffarpur town. Almost flat
topography with low lying central portion, heavy rainfall during the monsoon compounded
with occasional high water level in the Burhi Gandak river causes water logging and
occasional flooding. The major drainage channel of the Project Area is the Furdoo nala to
the West and South and Burhi Gandak River to the North and North-East.
Basically the drainage structure of the Muzaffarpur was constructed in a British era to
allow flood water from Burhi Gandak for irrigation purpose. Subsequently this system is
converted to a drainage system. The Warsley Road- Brahmapura Road-Kachi Sarai Road
forms a virtual watershed. The drains to the Eastern side of it flows to the North and
North-East direction and discharges to Burhi Gandak river while the drains in the Western
side of this road, flows in the to the South, South West and South East to Furdoo nala.
Other drains flow towards North and North East and discharges to the low lying area near
the old course of the Burhi Gandak River.
Industrial Effluents. Industries are outside the town area. The industries are required to
treat their own effluents before disposal and are not allowed by the Muzaffarpur Municipal
Corporation (MMC) to connect to the local sewer network.
Solid Waste. The menace of solid waste is creating havoc in Muzaffarpur. It produces
around 128 MT of solid waste everyday @ of 0.36 kg/capita/day. The present solid waste
management system is inadequate and improper. The town being almost flat, and
receiving a heavy rainfall during rainy seasons, it is necessary that a comprehensive solid
waste management system is put in place, so that the drainage and sewer lines are litter
free and allowed to perform its role in making the town liveable.
Transportation. Muzaffarpur is connected by broad gauge railway line on Motihari –
Samastipur section of the Eastern Railway. Further a railway line on the south connects
Muzaffarpur with the State capital Patna. Different values of total road lengths and
distribution of that length of road under different categories are obtained from several
sources. An old survey data obtained from the municipality sources gives a total road
length of 147 km. with following break-up.

3.4 Social and Cultural Resources
Demography. The Muzaffarpur district has a total population of 3746714 persons as per
Census 2001. It is the 3rd
largest district in Bihar in 2001 in terms of population, accounting
for 4.5% of the State‘s population. Muzaffarpur town is the only Class – I town in the
district. The other two urban centers are Kanti (20,871) and Motipur (21,957) which are
relatively smaller compared to Muzaffarpur.
As of the 2001 India census, Muzaffarpur town had a population of 305,465. Males
constituted 54% of the population and females 46%. Muzaffarpur had a literacy rate of
60%, close to the national average of 59.5%. Male literacy was 62%, and female literacy
was 57%. Thirteen percent of the population was under 6 years of age. The overall density
of Muzaffarpur town is 114 persons per hectare as per 2001 Census. The ward wise
density shows ward 39 having highest density (476 persons/ha) followed by ward 44 (396
persons/ha) and ward 22 (386 persons/ha). Similarly ward 49 has the lowest density (21
persons/ha) with increasing order of ward 12 (39 persons/ha) and ward 45 (40 persons/ha)
having similar low densities.
Health and Educational Facilities. At present Muzaffarpur has number of good
educational institutions. Muzaffarpur has 75 pre-primary schools, 37 primary schools, 20
secondary schools and a number of colleges. The overall literacy rate in Muzaffarpur is
high and the town already has a fairly elaborate network of educational institutions from
the pre-primary/ primary to the higher education and college level. In Muzaffarpur,
however, the spatial distribution of educational facilities is quite inequitable, with the outer
zones and the villages in the extension areas having fewer facilities.
Muzaffarpur has a number of health facilities including hospitals, polyclinics, nursing
homes and dispensaries. Lists of these available facilities are given below.

History, Culture, and Tourism. Muzaffarpur district, ‗The Land Of Leechi‘ was created in
1875 for the sake of administrative convenience by splitting up the earlier district of Tirhut.
The present district of Muzaffarpur came to its existence in the 18th century and named
after Muzaffar Khan, an Amil (Revenue Officer) under British Dynasty. Now it has won
international encomiums for its delicious Shahi Leechi and China Leechi. From the visit of
the Hieuen Tsang‘s till the rise of the Pala dynasty, Muzaffarpur was under the control of
Maharaja Harsha Vardhan, a powerful sovereign of North India. After 647 A.D. The district
passed on to the local chiefs. In the 8th century A.D. the Pala kings continued to have their
hold over Tirhut until 1019 A.D. Chedi kings of Central India also exercised their influence
over Tirhut till they were replaced by the rulers of the Sena dynasty towards the close of
the 11the century. Between 1211 & 1226, Ghais-u-ddin Iwaz, the ruler of Bengal, was the
first Muslim invader of Tirhut. He, however, could not succeed in conquering the kingdom
but extorted tributes. It was in 1323 that Ghiyasuddin Tughlaq established his control over
the district. Towards the close of the 14th century the whole of North Bihar including Tirhut
passed on to the kings of Jaunpur and remained under their control for nearly a century
until Sikandar Lodi of Delhi defeated the king of Jaunpur. Meanwhile, Hussain Shah, the
Nawab of Bengal had become so powerful that he exercised his control over large tracts
including Tirhut. The emperor of Delhi advanced against Hussain Shah in 1499 and got
control over Tirhut after defeating its Raja. The power of the Nawabs of Bengal began to
wane and with the decline and fall of Mahood Shah, north Bihar including Tirhut formed a
part of the mighty Mughal Empire.
Muzaffarpur played a very significant role in the history of North-Eastern India. The
peculiarity of Muzaffarpur in Indian civilization arises out of its position on the frontier line
between two most vibrant spiritual influences and most significantly, to this day, it is a
meeting place of Hindu and Islamic culture and thoughts. All sorts of modified institutions,
representing mutual assimilation, rise along the border line. It has undoubtedly been this
highly diversified element within her boundaries that has so often made Muzaffarpur the
birthplace of towering geniuses.
Muzaffarpur has a few locations of regional / local significance. Some of these are given
below.
Baba Garibnath temple Chaturbhujsthan temple Gola Durga temple Bangla Mukhi temple Pankha Toli mosque Bishops‘ House church and European church.
.Muzaffarpur accounts for 7.97% of total tourists coming to Bihar. Of this about 58.58% is
day tourists and 41.42% tourists are staying overnight. Muzaffarpur, received a total tourist
inflow of 4, 66,026 persons, of which day tourists accounted for 54%. Analysis shows that
the period from January to March receives one third of the total annual tourists Inflow of
foreign tourists to Muzaffarpur is almost negligible.
The subproject sites are not located in or near any historically, culturally, archaeologically
or architecturally significant areas.
4 Anticipated Impacts and Mitigation Measures
This section of the IEE reviews possible subproject-related impacts, in order to identify
issues requiring further attention and screen out issues of no relevance. ADB SPS (2009)
require that impacts and risks will be analyzed during pre-construction, construction, and
operational stages in the context of the subproject‘s area of influence. As defined
previously, the primary impact areas are (i) the sites for STP, pumping stations, outfall and
trunk sewer part, secondary and tertiary sewerage network; (ii) main routes/intersections
which will be traversed by construction vehicles; and (ii) quarries and borrow pits as
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 22
sources of construction materials. The secondary impact areas are: (i) entire Muzaffarpur
area outside of the delineated primary impact area; and (ii) entire Muzaffarpur district in
terms of over-all environmental improvement.
The ADB Rapid Environmental Assessment Checklist for Wastewater found in the
Environmental Assessment Guidelines (2003) was used to screen the subproject for
environmental impacts and to determine the scope of the IEE investigation. The completed
Checklist is found in Annex 3. All the proposed subproject components will interact
physically with the environment.
In the case of this subproject (i) most of the individual elements are relatively small and
involve straightforward construction and operation, so impacts will be mainly localized and
not greatly significant; (ii) most of the predicted impacts are associated with the
construction process, and are produced because that process is invasive, involving
excavation and earth movements; and (iii) being located in the built-up area of
Muzaffarpur, will not cause direct impact on biodiversity values. The STP will be on
private agricultural land requiring land acquisition (see Resettlement Plan for the
subproject) and access to the subproject area is through public rights-of-way and existing
roads hence.
4.1 Pre-construction – Location and Design
Design of the proposed components. The subproject has been designed for 30-years
life. Accordingly, it is proposed that the subproject be commissioned by the year 2013 and
the plan horizon year will be 2041. The design was based on a population forecast and
demand calculations for the mid period, year 2026. .
Location. Proposed STP site is located in open agricultural land and within about 3 km of
the Municipal boundary. Acquisition of a private land (8 ha) will be required for
construction of STP and this has been included in the subproject‘s Resettlement Plan.
Availability of environmentally-suitable lands for an STP is very limited in Muzaffarpur
since mostly are used for agricultural purposes and in close proximity to sensitive
receptors (residences, schools, religious and historical sites). The present site has been
considered because it is located in an area of: (i) at least 500 m from any inhabited areas;
(ii) no risk of flooding or other hazards that might impair the functioning of the plant; (iii) no
risk of chance finds; (iv) no waterway that is a source of water for domestic or municipal
supply; and (v) available right-of-way for the sewer network.
Sewerage Network. There are 9 sewage zones have been proposed for Muzaffarpur
town. Laying of sewerage network laterals and main line in core and densely populated
areas of the town. The design of the sewer network conforms to the Central Public Health
and Environmental Engineering Organization (CPHEEO) Manual on Sewerage and
Sewage Treatment. A schematic diagram showing STP, pump houses, sewerage network,
and trunk sewer enclosed in the Figure 5 of Section II.
Sludge Management. The biological sludge generated from the aeration tank will be
treated in the sludge handling system comprising a gravity thickener and a mechanical
dewatering unit like centrifuge or filter press. The generated sludge will be dewatered
mechanically in centrifuge or filter press. After dewatering it will have a solid content of
25%. The sludge generated from the aeration tank and as thickened and dewatered in
different units are listed below:

The annual sludge production will be 3615 m3/d when the plant is operated in its full
capacity. Immediately after the completion of the project the annual sludge production rate
will be 2710 m3/d.
If the sludge has to be stored temporarily within the plant area, a 50 m x 40 m area will be
enough to have a sludge storage height of 1.3 m to 1.8 m, which is acceptable.
This sludge will have good value as manure, so can be sold to the nearby villages. It may
be noted that Muzaffarpur is the only urban centre in the Mushahari block where there are
117 villages. People in this village mostly engaged in agriculture. Thus sewage sludge,
which has a high value as soil conditioner and manure, will find a good market here. There
will be no requirement for separate sludge disposal.
Utilities. Telephone lines, electric poles and wires, water and sewer lines within the
existing right-of-way (ROW) may be damaged. To mitigate the adverse impacts due to
relocation of the utilities, DSC will (i) identify and include locations and operators of these
utilities in the detailed design documents to prevent unnecessary disruption of services
during construction phase; and (ii) require construction contractors to prepare a
contingency plan
Asbestos Cement (AC) Pipes. An additional, particularly acute health risk presented by
this subproject derives from the fact that, the existing water supply system may comprises
AC pipes, so there is a risk of contact with carcinogenic material if these pipes are
uncovered in the course of the work. Precautions have already been introduced into the
design of the project to avoid this, of which the most important are that:
(i) No work is proposed on those parts of the existing system that contains AC pipes (ring, carrier, and distribution mains), and these will be left in-situ undisturbed, so there will be no deliberate excavation of AC pipes; and
(ii) The locations of the new network has been planned to avoid all locations of existing AC pipes so these pipes will not be discovered accidentally.
However unlikely, the design consultant should develop a protocol to be applied in any
instance that AC pipes are found, to ensure that appropriate action is taken. This should
be based on the approach recommended by the United States Environmental Protection
Agency (USEPA),1 and amongst other things, should involve:
(i) Develop reporting procedures to inform management immediately if AC pipes are encountered; and
(ii) Require construction consultants to develop and apply an AC Management Plan, as part of the over-all health and safety (H and S) plan, to protect both workers and citizens in case accidental uncovering of AC pipes. This AC Management Plan should also contain national and international standards for safe removal and long-term disposal of all asbestos-containing material encountered.
1 In the USA, standards and approaches for handling asbestos are prescribed by the Occupational Health
and Safety Administration (OHSA) and the Environmental Protection Agency (EPA) and can be found at http://www.osha.gov/SLTC/asbestos
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 24
Social and Cultural Resources. Muzaffarpur is a historic site (describe in part D of
Section III), and large numbers of temples and other religious sites, so there is a risk that
any work involving ground disturbance can uncover and damage archaeological and
historical remains. For this subproject, excavation will occur in and around existing ROWs,
so it could be that there is a low risk of such impacts. Nevertheless, PIU/DSC will:
(i) Consult archaeological Survey of India (ASI) to obtain an expert assessment of the archaeological potential of the site;
(ii) Consider alternatives if the site is found to be of medium or high risk;
(iii) Include state and local archaeological, cultural and historical authorities, and interest groups in consultation forums as project stakeholders so that their expertise can be made available; and
(iv) Develop a protocol for use by the construction contractors in conducting any excavation work, to ensure that any chance finds are recognised and measures are taken to ensure they are protected and conserved.
Site selection of construction work camps, stockpile areas, storage areas, and
disposal areas. Priority is to locate camps near the project area. However, if it is deemed
necessary to locate elsewhere, sites to be considered will not promote instability and result
in destruction of property, vegetation, irrigation, and drinking water supply systems.
Residential areas will not be considered in order to protect the communities (i.e., to curb
accident risks, health risks due to air and water pollution and dust, and noise, and to
prevent social conflicts, shortages of amenities, and crime). Extreme care will be taken to
avoid disposals near the restrict zone, wetlands, swamps, or in areas which will
inconvenience the community. All locations would be included in the design specifications
and on plan drawings.
Site selection of sources of materials. Extraction of materials can disrupt natural land
contours and vegetation resulting in accelerated erosion, disturbance in natural drainage
patterns, ponding and water logging, and water pollution. To mitigate the potential
environmental impacts, locations of quarry site/s and borrow pit/s (for loose material other
than stones) would be included in the design specifications and on plan drawings. Priority
would be sites already permitted by Mining Department. If other sites are necessary, these
would to be located away from population centers, drinking water intakes and streams,
cultivable lands, and natural drainage systems; and in structurally stable areas even if
some distance from construction activities. It will be the construction contractor‘s
responsibility to verify the suitability of all material sources and to obtain the approval of
Urban Local Body. If additional quarries will be required after construction is started, then
the construction contractor shall use the mentioned criteria to select new quarry sites, with
written approval of Muzaffarpur Municipal Corporation.
4.2 Construction
1. Screening of No Significant Impacts
The construction work is not expected to cause major negative impacts, mainly because:
(i) Most of the activities will be on the built-up areas of Muzaffarpur town thus could be constructed without causing impacts to biodiversity;
(ii) The site is located more or less in government-owned land (except private land for STP) which is not occupied or used for any other purpose;
(iii) Overall construction program will be relatively short and is expected to be completed in 30 months, with activities to conducted by small teams working on short lengths at a time so most impacts will be localized and short in duration; and
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 25
(iv) Most of the predicted impacts associated with the construction process are produced because the process is invasive, such as involving earth-moving and excavation. However the routine nature of the impacts means that most can be easily mitigated and the impacts are clearly a result of the construction process rather than the design or location, as impacts will not occur if excavation or other ground disturbance is not involved.
As a result, there are several aspects of the environment which are not expected to be
affected by the construction process and these can be screened out of the assessment at
this stage as required by ADB procedure. These are shown in Table 7. These
environmental factors are screened out presently but will be assessed again before
starting of the construction activities.

2. Construction method
Although the site is not fairly large, the STP construction will be straightforward involving
mainly simple excavation. The ponds will be dug by backhoe diggers and bulldozers, and
soil will be transferred into trucks for offsite disposal. Clay will then be applied to the floor
and sloping sides of each pond and after watering will be covered with low density poly-
ethylene (LDPE) sheeting and concreting in some parts. A thin layer of cement mortar is
then added, and concrete tiles are embedded into the surface by hand, with more cement
grouting applied to seal joints between tiles.
For trunk, tertiary pipe laying most pipes will be buried in trenches immediately adjacent to
roads, in the un-used area within the ROW, alongside the edge of the tarmac. The trunk
main and secondary network will be located alongside main roads, where there is
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 26
generally more than enough free space to accommodate the pipeline. However in parts of
the tertiary network where roads are narrow, this area is occupied by drains or the edges
of shops and houses etc., so the trenches may have to be dug into the edge of the road.
Trenches will be dug by backhoe digger, supplemented by manual digging where
necessary. Excavated soil will be placed nearby, and the pipes (brought to site on trucks
and stored on unused land nearby) will be placed in the trench by crane or using a small
rig. After the pipes are joined, loose soil will be shovelled back into the trench, and the
surface layer will be compacted by hand-operated compressor.
Pipes are normally covered by 1.2 m of soil, and a clearance of 100 mm is left between
the pipe and each side of the trench to allow backfilling. Trenches will therefore be quite
large, a maximum of 2.3 m deep and 1.2 m wide for the trunk main, and a minimum of 1.5
m deep and 0.4 m wide for the secondary/ tertiary network.
At intervals, small chambers (ca 1-2 m3) will be created to allow inspection and clearance
of blockages and sediment during operation. These will be excavated by backhoe and
hardcore and concrete (mixed on site) will be tipped in to form the base. Brick sides will
then be added by masons by hand, and the top will be sealed at ground level by a metal
manhole cover.
As noted above, some of the narrower roads are constructed of concrete and have no
available space at the edge because of the presence of drains, or shop- and house-fronts
encroaching into the ROW. In these places it may be necessary to break open the surface
of the road using hand-held pneumatic drills, after which the trench and pipeline will be
constructed as described above. On completion, a concrete layer will be re-applied to the
surface to repair the road.
Foundations for the small pump houses will be dug by backhoe, and concrete and
aggregate will be tipped in to create the foundations and floor. The brick sides will then be
built by hand by masons and pumps will be brought in on trucks and placed inside the
pump.
3. Anticipated Impacts and Mitigation Measures
Although construction of the subproject components involves quite simple techniques, the
invasive nature of excavation, and in this case the relatively large size and length of the
pipes, means that there will be quite a lot of physical disturbance in the built-up areas of
Muzaffarpur town where there are a variety of human activities.
Physical impacts will be reduced by the method of working, whereby the trenches will be
(i) constructed by small teams working on short lengths at a time; (ii) refilled and
compacted after pipes are installed; and (iii) if trenching done on roads, repaired to pre-
construction conditions.
Sources of Materials. Significant amount of gravel, sand, and cement will be required for
this subproject. The construction contractor will be required to:
(i) Use quarry sites and sources permitted by government;
(ii) Verify suitability of all material sources and obtain approval of PMU;
(iii) If additional quarries will be required after construction has started, obtain written approval from PMU; and
(iv) Submit to DSC on a monthly basis documentation of sources of materials.
Air Quality. Emissions from construction vehicles, equipment, and machinery used for
excavation and construction will induce impacts on the air quality in the construction sites.
Anticipated impacts include dusts and increase in concentration of vehicle-related
pollutants such as carbon monoxide, sulphur oxides, particulate matter, nitrous oxides,
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 27
and hydrocarbons) but temporary and during construction activities only. To mitigate the
impacts, construction contractors will be required to:
(i) Consult with PIU/DSC on the designated areas for stockpiling of clay, soils, gravel, and other construction materials;
(ii) Excavate the pump house foundations and STP site at the same time as the access roads are built so that dug material is used immediately, avoiding the need to stockpile on site;
(iii) Damp down exposed soil and any stockpiled on site by spraying with water when necessary during dry weather;
(iv) Use tarpaulins to cover sand and other loose material when transported by trucks; and
(v) Fit all heavy equipment and machinery with air pollution control devices which are operating correctly.
Surface Water Quality. Construction activities for STP will be conducted near nala,
although dried up during the summer period, has significant amount of silt materials.
Mobilization of settled silt materials, run-off from stockpiled materials, and chemical
contamination from fuels and lubricants during construction works can contaminate
downstream surface water quality. These potential impacts are temporary and short-term
duration only and to ensure these are mitigated, construction contractor will be required to:
(i) Avoid stockpiling of earth fill especially during the monsoon season unless covered by tarpaulins or plastic sheets;
(ii) Prioritize re-use of excess spoils and materials in the construction works. If spoils will be disposed, consult with PIU/DSC on designated disposal areas;
(iii) Install temporary silt traps or sedimentation basins near water bodies;
(iv) Place storage areas for fuels and lubricants away from any drainage leading to water bodies;
(v) Dispose any wastes generated by construction activities in designated sites; and
(vi) Conduct surface quality inspection according to the Environmental Management Plan (EMP).
Noise Levels. There are no health facilities, religious sites, scheduled or unscheduled
historical, archaeological, paleontological, or architectural sites near the construction sites.
However, construction works particularly pipe laying work will be on settlements, along
schools, and areas with small-scale businesses. The sensitive receptors are the general
population in these areas. Increase in noise level may be caused by earth-moving and
excavation equipment, and the transportation of equipment, materials, and people. Impact
is negative, short-term, and reversible by mitigation measures. The construction contractor
will be required to:
(i) Plan activities in consultation with PIU/DSC so that activities with the greatest potential to generate noise are conducted during periods of the day which will result in least disturbance;
(ii) Require horns not be used unless it is necessary to warn other road users or animals of the vehicle‘s approach;
(iii) Minimize noise from construction equipment by using vehicle silencers, fitting jackhammers with noise-reducing mufflers, and portable street barriers the sound impact to surrounding sensitive receptor; and
(iv) Maintain maximum sound levels not exceeding 80 decibels (dbA) when measured at a distance of 10 m or more from the vehicle/s.
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 28
Existing Infrastructure and Facilities. Excavation works can damage existing
infrastructure located alongside roads, in particular water supply pipes. It will be
particularly important to avoid damaging existing water pipes as these are mainly
manufactured from Asbestos Cement (AC), which can be carcinogenic if inhaled, so there
are serious health risks for both workers and the public. It is therefore important that
construction contractors will be required to:
(i) Obtain from PIU and/or DSC the list of affected utilities and operators;
(ii) Prepare a contingency plan to include actions to be done in case of unintentional interruption of services. and
(iii) Develop and implement an AC Pipes Management Plan
Landscape and Aesthetics. The construction works will produce excess excavated soils,
excess construction materials, and solid waste such as removed concrete, wood, trees
and plants, packaging materials, empty containers, spoils, oils, lubricants, and other
similar items. These impacts are negative but short-term and reversible by mitigation
measures. The construction contractor will be required to:
(i) Prepare and implement Waste Management Plan;
(ii) Avoid stockpiling of excess excavated soils;
(iii) Coordinate with Muzaffarpur Municipal Corporation (MMC) for beneficial uses of excess excavated soils or immediately dispose to designated areas;
(iv) Recover used oil and lubricants and reuse or remove from the sites;
(v) Manage solid waste according to the following preference hierarchy: reuse, recycling and disposal to designated areas;
(vi) Remove all wreckage, rubbish, or temporary structures (such as buildings, shelters, and latrines) which are no longer required; and
(vii) Request PIU/DSC to report in writing that the necessary environmental restoration works has been adequately performed before acceptance of work.
Ecological Resources. There are no significant ecological resources in or around the
project area of the town, so construction work can be conducted without ecological
impacts. Except at STP site in village Khabara 10-15 trees need to be felled. As per
standard norm 3 trees need to be planted against each tree felling. Moreover in STP
design buffer zone plantation will be considered for compensating ecological resources.
Surface and Groundwater Quality. Another physical impact that is often associated with
large-scale excavation is the effect on drainage and the local water table if groundwater
and surface water collect in the voids. However, this should not be a problem in this
subproject, given the low rainfall and deep water table in this area. To ensure that water
will not pond in pits and voids near subproject sites, the construction contractor will be
required to conduct excavation works on non-monsoon season.
Accessibility. Hauling of construction materials and operation of equipment on-site can
cause traffic problems and conflicts in ROW. Potential impact is negative but short term
and reversible by mitigation measures. The construction contractor will be required to:
(i) Plan transportation routes so that heavy vehicles do not use narrow local roads, except in the immediate vicinity of delivery sites;
(ii) Schedule transport and hauling activities during non-peak hours;
(iii) Locate entry and exit points in areas where there is low potential for traffic congestion;
(iv) Keep the site free from all unnecessary obstructions;
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 29
(v) Drive vehicles in a considerate manner;
(vi) Coordinate with Traffic/Police department of Muzaffarpur for temporary road diversions and with for provision of traffic aids if transportation activities cannot be avoided during peak hours; and
(vii) Notify affected sensitive receptors by providing sign boards informing nature and duration of construction works and contact numbers for concerns/complaints.
Socio-Economic – Income. The subproject components will be located on government
lands (except STP location) and ROWs, so there will be no need to acquire land, and thus
there will be no impacts on the asset or landowners or tenants. However construction
works will impede the access of residents and customers to nearby shops. The potential
impacts are negative and moderate but short-term and temporary. The construction
contractor will be required to:
(i) Leave spaces for access between mounds of soil;
(ii) Provide walkways and metal sheets where required to maintain access across trenches for people and vehicles;
(iii) Increase workforce in front of critical areas such as institutions, place of worship, business establishment, hospitals, and schools;
(iv) Consult businesses and institutions regarding operating hours and factoring this in work schedules; and
(v) Provide sign boards for pedestrians to inform nature and duration of construction works and contact numbers for concerns/complaints.
Socio-Economic – Employment. Manpower will be required during the 30-months
construction stage. This can result to generation of contractual employment and increase
in local revenue. Thus potential impact is positive and long-term. The construction
contractor will be required to:
(i) Employ at least 50% of the labour force, or to the maximum extent, local persons within the 2-km immediate area if manpower is available; and
(ii) Secure construction materials from local market.
Occupational Health and Safety. Workers need to be mindful of the occupational
hazards which can arise from working in trenches and excavation works. Potential impacts
are negative and long-term but reversible by mitigation measures. The construction
contractor will be required to:
(i) Develop and implement site-specific Health and Safety (H and S) Plan which will include measures such as: (a) excluding public from the site; (b) ensuring all workers are provided with and use Personal Protective Equipment; (c) health and safety Training2 for all site personnel; (d) documented procedures to be followed for all site activities; and (e) documentation of work-related accidents;
(ii) Ensure that qualified first-aid can be provided at all times. Equipped first-aid stations shall be easily accessible throughout the site;
2 Some of the key areas that may be covered during training as they relate to the primary causes of
accidents include (i) slips, trips and falls; (ii) personal protective equipment; (iii) ergonomics, repetitive motion, and manual handling; (iv) workplace transport; and (v) legislation and responsibilities. Training can provide the foundations of competence but it does not necessarily result in a competent worker. Therefore, it is essential to assess staff competence to ensure that the training provided is relevant and effective. Supervision and monitoring arrangements shall be in place to ensure that training has been effective and the worker is competent at their job. The level of supervision and monitoring required is a management decision that shall be based on the risks associated with the job, the level of competence required, the experience of the individual and whether the worker works as part of a team or is a lone worker.
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 30
(iii) Provide medical insurance coverage for workers;
(iv) Secure all installations from unauthorized intrusion and accident risks;

A particular acute health risk presented by this subproject the risk of contact with
carcinogenic material if the AC pipes are uncovered in the course of work. Precautions
have already been introduced into the design of the subproject to avoid uncovering of
these AC pipes. However unlikely, the construction contractor will be required to:
(i) Train all personnel (including manual labourers) to enable them to understand the dangers of AC pipes and to be able to recognise them in situ;
(ii) Report to management immediately if AC pipes are encountered;
(iii) Develop and apply AC Management Plan.
Community Health and Safety. Hazards posed to the public, specifically in high-
pedestrian areas may include traffic accidents and vehicle collision with pedestrians.
Potential impact is negative but short-term and reversible by mitigation measures. The
construction contractor will be required to:
(i) Plan routes to avoid times of peak-pedestrian activities.
(ii) Liaise with PIU/DSC in identifying high-risk areas on route cards/maps.
(iii) Maintain regularly the vehicles and use of manufacturer-approved parts to minimize potentially serious accidents caused by equipment malfunction or premature failure.
(iv) Provide road signs and flag persons to warn of dangerous conditions.
Work Camps. Operation of work camps can cause temporary air and noise pollution from
machine operation, water pollution from storage and use of fuels, oils, solvents, and
lubricants. Potential impacts are negative but short-term and reversible by mitigation
measures. The construction contractor will be required to:
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 31
(i) Consult with PIU/DSC before locating project offices, sheds, and construction plants;
(ii) Minimize removal of vegetation and disallow cutting of trees;
(iii) Provide water and sanitation facilities for employees;
(iv) Prohibit employees from cutting of trees for firewood;
(v) Train employees in the storage and handling of materials which can potentially cause soil contamination;
(vi) Recover used oil and lubricants and reuse or remove from the site;
(vii) Manage solid waste according to the following preference hierarchy: reuse, recycling and disposal to designated areas;
(viii) Remove all wreckage, rubbish, or temporary structures (such as buildings, shelters, and latrines) which are no longer required; and
(ix) Request PIU/DSC to report in writing that the camp has been vacated and restored to pre-project conditions before acceptance of work.
Social and Cultural Resources. For this subproject, excavation will occur in and around
existing ROWs, so it could be that there is a low risk of such impacts. Nevertheless, the
construction contractor will be required to:
(i) Strictly follow the protocol for chance finds in any excavation work;
(ii) Request PIU/DSC or any authorized person with archaeological field training to observe excavation;
(iii) Stop work immediately to allow further investigation if any finds are suspected; and
(iv) Inform PIU/DSC if a find is suspected, and take any action they require ensuring its removal or protection in situ.
4.3 Operation and Maintenance
1 Screening out areas of no significant impact
Although the sewerage system will need regular maintenance when it is operating, with a
few simple precautions this can be conducted without major environmental impacts (see
below). There are therefore several environmental factors which should be unaffected by
this system once it begins to function. These are identified in Table 8 below, with an
explanation of the reasoning in each case. These factors are thus screened out of the
impact assessment and will not be discussed further.
Table 8: Fields in which operation and maintenance of the completed sewerage system is not expected to have significant impacts
Field Rationale
Climate, topography, geology, seismology
There are no known instances where the operation of a relatively small sewerage system has affected these factors
Fisheries and aquatic biology No fishery nearby the project location
Wildlife, forests, rare species, protected areas
There are no wildlife, forests, rare species, and protected areas at sub-project locations
Coastal resources Muzaffarpur is not located in a coastal area
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 32
2. Operation and Maintenance of new Sewerage System
The new sewerage system will collect and treat all surface water, domestic wastewater
and sewage produced by the town, and the remainder of the inhabited area and future
expansion will be served by additional sewers provided via subsequent tranches of funds.
Although treatment will not be to the standards of more developed countries, the
technology is approved by the CPHEEO. Treatment technology is shown in Annex 2. The
final effluent quality through Extended Aeration based technology is excellent even for
discharge to inland surface water. The Indian discharge standard for treated effluent is
depicted in Table 9.

The sewer pipes will not function without maintenance, as silt inevitably collects in areas of
low flow over time. The project will therefore provide equipment for cleaning the sewers,
including buckets and winches to remove silt via the inspection manholes, diesel-fuelled
pumps to remove blockages, and tankers to transport the waste hygienically to the STP.
Piped sewers are not 100% watertight and leaks can occur at joints. Any repairs will be
conducted by sealing off the affected sewer and pumping the contents into tankers, after
which the faulty section will be exposed and repaired following the same basic procedure
as when the sewer was built. Trenches will be dug around the faulty section and the
leaking joint will be re-sealed, or the pipe will be removed and replaced.
At the STP, the biological sludge generated from the aeration tank will be treated in the
sludge handling system comprising a gravity thickener and a mechanical dewatering unit
like centrifuge or filter press. The generated sludge will be dewatered mechanically in
centrifuge or filter press. After dewatering it will have a solid content of 25%. After that
sludge will stored within STP and finally disposed off as manure for agricultural use.
The treatment and drying processes kill enteric bacteria and pathogens, and because of
its high content of nitrates, phosphates and other plant nutrients the sludge is an excellent
organic fertilizer and farmers are normally allowed to remove the dry material for
application to their land. Treated wastewater can also be used as source of irrigation
during dry period.
3. Anticipated Environmental Impacts and Mitigation Measures
General. If trenches will be dug to locate and repair leaks or remove and replace lengths
of pipe or illegal connections, the work will follow the same procedures during the
construction stage. MMC needs to require its O& M contractor to:
(i) Refill and re-compact trenches soil and backfilled sand will be removed to expose the leaking junction or pipe;
(ii) Conduct work during non-monsoon period; and
(iii) Cover or wet excavated material to prevent dusts.
Ecological Resources. There are no significant ecological resources in or around the
project area of the town, so any repairs or maintenance work can be conducted without
ecological impacts. As there is no significant flora and fauna in or around project site, there
should also not be any ecological impacts from the operation of sewerage system.
Economic Development. Although repair of pipelines could result in shops losing some
business if the work means that access is difficult for customers, any losses will be small
and short-lived and will probably be at the level of normal business fluctuations. It should
therefore not be necessary to compensate for such losses. Nevertheless MMC needs to
require its O & M contractor to:
(i) Inform all residents and businesses about the nature and duration of any work well in advance so that they can make preparations if necessary;
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 34
(ii) Conduct these works to provide wooden walkways across trenches for pedestrians and metal sheets where vehicle access is required; and
(iii) Consult the local police regarding any such work so that it can be planned to avoid traffic disruption as far as possible, and road diversions can be organised if necessary.
The use of local contractors will provide economic benefits to the companies and the
workers they employ. There is however little prospect of directing these benefits to
persons affected by any maintenance or repair works as contractors will utilise their
existing workforce. To provide at least some economic benefits to affected communities,
unskilled persons employed to maintain and operate the STP should be residents of the
neighbouring area.
Social and Cultural Resources. Although there is a high risk of excavation in the town
discovering material of historical or archaeological importance, there will be no need to
take precautions to protect such material when areas are excavated to repair leaks in the
network, as all work will be conducted in trenches that have already been disturbed when
the infrastructure was installed.
Repair works could cause some temporary disruption of activities at locations of social and
cultural importance such as schools, hospitals, temples, tourist sites etc, so the same
precautions as employed during the construction period should be adopted. MMC/PHED
needs to require its O & M contractor to:
(i) Consult the town authorities to identify any buildings at risk from vibration damage and avoiding any use of pneumatic drills or heavy vehicles in the vicinity;
(ii) Complete work in these areas quickly;
(iii) Provide wooden bridges for pedestrians and metal sheets for vehicles to allow access across open trenches where required; and
(iv) Consult municipal authorities, custodians of important buildings, cultural and tourism authorities and local communities in advance of the work to identify and address key issues, and avoid working at sensitive times, such as religious and cultural festivals.
The citizens of the town will be the major beneficiaries of the new sewerage system, as
human waste from those areas served by the new network will be removed rapidly and
treated to an acceptable standard. This should improve the environment of these areas,
and in conjunction with the development of other infrastructure (in particular water supply),
should deliver major improvements in individual and community health and well-being.
Diseases of poor sanitation, such as diarrhea and dysentery, should be reduced, so
people should spend less on healthcare and lose fewer working days due to illness, so
their economic status should also improve, as well as their overall health.

The affected persons can register their grievances at the complaint cell established at the
ULB/PIU office. The Complaint Cell would forward the grievance to the (Social &
Environmental) S&E Safeguard officer for redressal. The Complaint Cell will also act as a
Public Information Centre, where the grievances of the community will be registered and
other information with regard to the project, the sub-projects, social and environmental
safeguards will be provided. The grievances can pertain to any social and/or
environmental issues triggered by sub-projects under the BUDIP. A ‗District Urban
Grievance Redressal Body‘ will be established for giving independent advice to the
concerned Municipal Commissioner for redressing the grievances. This body will consist
of 4 to 5 eminent citizens in the District and are from diverse backgrounds such as,
education, health and sanitation, urban infrastructure, civic affairs, etc. In an advisory
capacity, it will facilitate and suggest suitable action to redress the grievances of the
community/people. At the state level a ‗State Urban Grievance Redressal Body‘ will be
established along similar lines. The Complaint Cell would forward the grievance to the
S&E officer for redressal. If the S&E officer cannot redress the grievance within a specified
time period, the grievance would be forwarded to the ESMC and further to the District
Urban Grievance Redressal Body constituted at the district level. The grievances which
cannot be redressed at the district level would be referred to the State Urban Grievance
Redressal Body. Each of these authorities can be approached directly for grievance
redressal by the aggrieved person/party.

7.4 Environmental Management Plan Costs
Most of the mitigation measures require the Construction Contractors to adopt good site
practice, which should be part of their normal procedures already, so there are unlikely to
be major costs associated with compliance. Regardless of this, any costs of mitigation by
the construction contractors or DSC are included in the budgets for the civil works and do
not need to be estimated separately here. Mitigation that is the responsibility of UDHD will
be provided as part of their management of the project, so this also does not need to be
duplicated here.
The remaining actions in the EMP are the various environmental monitoring activities to be
conducted by the Environmental Monitoring Specialist. These have not been budgeted
elsewhere, and their costs are shown in Table 16. The figures show that the total cost of
environmental management and monitoring for the subproject as a whole (covering
design, 2 years of construction and the first five years of operation) is INR 0.87 million, ie
US$ 19,334.

8 Findings and Recommendations
1 The environmental impacts of all elements of the infrastructure proposed under the
Muzaffarpur Sewerage and Sanitation Subproject were assessed. Potential negative
impacts were identified in relation to both construction and operation of the improved
infrastructure, but no major impacts were identified as being due to either the project
design or location. Only for construction of STP acquisition of private land is necessary.
Mitigation measures have been developed in generic way to reduce all negative impacts
to acceptable levels. These were discussed with specialists responsible for the
engineering aspects, and as a result some measures have already been included in the
outline designs for the infrastructure. This means that the number of impacts and their
significance has already been reduced by amending the design.
2 During the construction phase, impacts mainly arise from the need to dispose of large
quantities of waste soil and import a similar amount of sand to support the pipes in the
trenches; and from the disturbance of residents, businesses, traffic and important
5 Unit costs of domestic consultants include fee, travel, accommodation and subsistence
Bihar Urban Development Investment Programme
Appendix 1 - IEE: Muzaffarpur Sewerage and Sanitation 59
buildings by the construction work. These are common impacts of construction in urban
areas, and there are well developed methods for their mitigation.
3 The use of AC pipes (few cases only) in the existing water distribution network presents
a particular problem, as workers and the public will need to be protected from inhalation
of asbestos dust, which can be carcinogenic. This has been addressed in the EMP.
4 Once the system is operating, most facilities (STP, pump house) will operate with routine
maintenance, which should not affect the environment. Leaks in the sewage network will
need to be repaired from time to time, but environmental impacts will be much less than
those of the construction period as the work will be infrequent, affecting small areas
only. It will also be conducted in areas that have already been excavated, so there will
be no need to protect archaeological material.
5 The regular removal of sludge from the aeration tank and followed by sludge drying bed
should also have no environmental impacts, and if tests show that the drying procedure
removes bacterial contamination the material should be sold to farmers to fertilize soil,
as this will provide an environmental gain and some cost recovery.
6 The main impacts of the operating sewerage system will be beneficial as human waste
from those areas served by the new network will be removed rapidly and treated to an
acceptable standard. This will improve the environment and appearance of these areas,
and the health and quality of life of the citizens. Diseases of poor sanitation should be
reduced, which should lead to economic gains as people will be away from work less
and will spend less on healthcare, so their incomes should increase.
7 Mitigation will be assured by a program of environmental monitoring conducted during
both construction and operation to ensure that all measures are provided as intended,
and to determine whether the environment is protected as envisaged. This will include
observations on and off site, document checks, and interviews with workers and
beneficiaries, and any requirements for remedial action will be reported to the PMU.
There will also be longer-term surveys to monitor the quality of discharged treated
effluent and health status in vicinity of the facility.
9 Conclusions
The subproject is not determined to cause significant adverse impacts. The potential
adverse impacts that are associated with design, construction, and operation can be
mitigated to standard levels without difficulty through proper engineering design and the
incorporation or application of recommended mitigation measures and procedures. Based
on the findings of the IEE, the classification of the Project as Category ―B‖ is confirmed,
and no further special study or detailed EIA needs to be undertaken to comply with ADB
SPS (2009) or GoI EIA Notification (2006).

Annex 2 Proposed STP Technology: Extended Aeration System
Process Details
Extended aeration system is basically a modification of the conventional activated sludge process. The biological removal and conversion of organic wastes in an activated sludge plant takes place in two stages: first the organic waste is partially oxidized for energy and partially synthesized into new cells. Then in the second stage with continued aeration the biological cells undergo self oxidation for further energy. The extended aeration process operates in the endogenous phase of the microbial growth curve. The system is designed on the basis of low organic loading rate (low food to micro organism ratio, F/M ratio), high biological solids concentration and longer aeration time to destruct (oxidise) the biomass (solids) generated from the endogenous respiration. The active biological solids utilize the oxygen while undergoing the endogenous respiration to oxidize the degradable portion of their cells to carbon dioxide and water with a resulting decrease in sludge mass. The main advantage of operating the system in at these conditions is that the excess sludge produced in the reactor is almost completely mineralized and thereby eliminates the requirement for further sludge digestion and treatment
6. However there is still some solid build up
in the aeration tank, which has to be wasted regularly
In the extended aeration system the raw sewage directly goes to the aeration tank only after the pre-treatment (screening and grit removal) and no primary clarification is done. The overflow from the aeration tank is discharged after clarification. This process has very high organic removal efficiency (95-98% BOD removal efficiency).
Preliminary Treatment
The Preliminary treatment involves screening and grit removal will be given to the raw sewage reaching the STP. Raw sewage will be discharged to the wet well after passing through coarse screen (opening 50 mm). From the wet well the raw sewage will be pumped to the inlet chamber of the sewage treatment plant. Then it will flow through screen channel and will pass through medium screen (opening 20-25 mm) for removal of large size floatable materials. Subsequently it will enter the grit channel where grit particles will be separated. A proportional flow weir will be installed at the end of the grit channel for maintaining a constant velocity (0.15 – 0.30 m/s) of flow through the channel under varying flow condition. There will be a number of screen channels and grit channels so that at least one channel can be kept as stand by under peak flow condition. There will be at least one manual screen and one mechanical screen. Timer based racking mechanism will be used to clean the screen periodically and put the screenings to belt conveyor system. Screened material is conveyed to collection van provided beneath the end of the belt conveyor for final disposal. CI Gates upstream and downstream to the screen are provided. The main units of the preliminary treatment will be as follows:
Inlet Chamber One number, for receiving raw sewage
Screens Mechanical Screens & Manual Screens
(one working + one stand-by)

Secondary Treatment
The major component of the Secondary treatment units are:
Aeration tank with surface aerator
Secondary clarifier : Mechanical sludge scraping devices
After passing through the grit chamber the sewage will be uniformly distributed among the aeration tanks from the division/flow distribution box. In the aeration tank microorganisms are mixed with the influent and the biodegradable portion is stabilized aerobically to produce the end product and new biomass. The oxygen in the aeration basin will be supplied by a number of surface aerators. The surface aerators will be vertically mounted tubes extending from just above the base of a deep concrete tank to just below the surface of the sewage liquor and the end of the tube is formed into a cone with helical vanes attached to the inner surface. The aerators will also help to provide the energy necessary for proper mixing. Hydraulic retention in the aeration tank will be between 12-24 hrs at average flow. Oxygenation capacity of each aerator is of 1.2 – 2.4 Kg of 02/kWh. F/M ratio varies between 0.10 and 0.15. MLSS concentration may vary between 3000 mg/l to 4000 mg/l. Aeration requirement is 1.2.Kg of O2 /Kg of BOD5 removed.
The overflow from the aeration tank goes to the secondary clarifier. This unit removes the bio-mass from the reactor effluent and returns a part of the bio-mass back to the reactor for maintaining desired MLSS concentration in the aeration tank in activated sludge plant. Liquid enters the clarifier through a central circular shaft. Floor of the clarifier is sloped at 1:12 to form an inverted cone to a central sludge pit. A sludge scraping mechanism facilitates the sludge to move to the central sludge pit from where it will be discharged to the sludge sump.
Disinfection and Disposal
The overflow from the clarifier will be disinfected in the chlorine contact tank. The chlorine dosing will be done by evaporator type of chlorinators. There will be a chlorinator with evaporator in the chlorination plant. Liquid chlorine shall be drawn from chlorine tonner and it will then pass through evaporator for vaporization. The gaseous chlorine shall be injected through ejector after mixing with water. Ultimate chlorine solution shall be dosed in chlorine contact tank. In chlorine contact tank, chlorine solution diffuser shall be provided for proper mixing of the solution.
Treated sewage after chlorine contact tank shall be taken to the river through RCC channel. Parshall flume along with ultrasonic flow meter shall be provided after chlorine contact tank in the RCC channel to measure the flow. The length of the channel shall be as per site condition. Capacity of the channel should be such that it can carry peak flow.
Sludge Handling System
The waste activated sludge from the sludge sump will be fed to the sludge thickener for gravity thickening. The thickened sludge from the bottom of the thickener will be fed to the centrifuge for mechanical dewatering. The dewatered sludge will be stored in a storage area and will be carted periodically for disposal.
The sludge handling system will consist of following units
i) Sludge sump and pumps: Recycling sludge pumps and excess sludge pumps.
ii) Sludge Thickener: The purpose of this unit is to increase the sludge consistency from 1% to 4% by gravity separation of liquid from solids.
iii) Centrifuge / Filter Press: This is a mechanical sludge dewatering facility. This will increase the solids content of the sludge from 3-4% at the inlet to 20 -25% at the outlet.
iv) Supernatant Sump and Pump: Receives flow from thickener & centrifuge/filter press and sends back to the inlet of STP.
Miscellaneous Units/items
i) Electric room / MCC: This will house the electric panels and OFF-ON Buttons.

Villages are located more than 500 m away from proposed STP location at Khabara
impairment of downstream water quality due to inadequate sewage treatment or release of untreated sewage?
Yes
No
At present the receiving water body, i.e., Furdoo nala is a drainage channel, mainly carrying storm water discharge (mixed with some untreated sewage) during monsoon and untreated sewage from the nearby isolated residential areas during dry periods.
After the installation of the STP only treated effluent (conforming to the discharge standard set by MoEF for discharge to Inland Surface water) will be discharged to Furdoo nala adjacent to the STP location. Hence the discharged effluent is not going to cause any impairment of downstream water quality
overflows and flooding of neighbouring properties with raw sewage?
Yes
No
All the raw sewage will be diverted to the STP and will be pumped to it for treatment to the required level before disposal.
The pumping stations will have adequate number of standby pumps and back up power system to take care of any exigency condition.
environmental pollution due to inadequate sludge disposal or industrial waste discharges illegally disposed in sewers?
Yes
No
The sludge will be collected and used as manure after digestion.
The town does not have any major polluting industry which discharges bulk quantity of raw effluent to the proposed sewer network meant for domestic effluent/sewage.
