Site Visit and Feasibility Report for Ranchi (Jharkhand)
A team of CSIR-NEERI visited Ranchi city and its suburban area Hatia (Jharkhand) on
07/03/2020 to see the current status of sewage flowing through drains and possibility of
installation of In-situ drain treatment system (RENEU) developed by CSIR-NEERI for
treatment of sewage flowing through drains before its discharge into any natural stream or
river. Ranchi city is situated on the banks of Subarnrekha river. Harmu river which is a
tributary of Subarnrekha river also flows through the city. In order to save our natural water
bodies, it is very necessary to treat the sewage flowing through drains before discharging it
into a river or stream. Sewage generated in Ranchi and its suburban areas goes into river
Subarnrekha and Harmu river through many drains. The preset status of water quality in
Subarnrekha river and Harmu river is not good due to discharge of untreated sewage into
these rivers. During the visit for the above said purpose, CSIR-NEERI team was
accompanied with officials from JUIDCO (Jharkhand Urban Infrastructure Development
Corporation). Satellite view of Ranchi is shown in Figure 1. A brief description of RENEU
technology (Restoration of Nallah with Ecological Units) is given as Annexure 1.
Fig. 1: Satellite view of Ranchi city
The details of drains which were visited in Ranchi are given below.
2 CSIR- National Environmental Engineering Research Institute
1. Drain at Tupudana Industrial area in Hatia
Location: 23.281261°N, 85.306337°E
Flow: 6 MLD approx.
The drain is unlined in the stretch before its confluence into Subarnarekha river. At this
location the river Subarnrekha is like a small stream having less flow of water in it and hence
it is more prone to pollution due to sewage or industrial effluent. The drain carries sewage as
well as industrial effluent which must be treated before its discharge into river. In-situ drain
treatment system (RENEU) of capacity 6 MLD may be provided for treatment of sewage
flowing through this drain. Site photograph of the drain is shown in Figure 2.
Approximate cost of the project would be 340 Lakhs including O&M for 5 year.
Approximate length of nallah where treatment system will be installed would be 220 meter.

3 CSIR- National Environmental Engineering Research Institute
2. Drain at Hatia town
Location: 23.284175°N, 85.308300°E
Flow: 1.5 MLD approx.
The drain is unlined in the stretch before its confluence into Subarnarekha river. At this
location the river Subarnrekha is like a small stream having less flow of water in it and hence
it is more prone to pollution due to sewage. The above mentioned drain carries sewage of
nearby locality which must be treated before its discharge into the river. Due to unavailability
of sufficient length of drain for provision of complete In-situ drain treatment system
(RENEU) of capacity 1.5 MLD it may be recommended to provide some essential units
which may include screen, sedimentation tank, florafts, etc. for partial treatment of sewage
flowing through this drain. Site photograph of the drain is shown in Figure 3.
Approximate cost of the project would be 70 Lakhs including O&M for 5 year.
Approximate length of nallah where treatment system will be installed would be 50 meter.

Location: 23.291221°N, 85.268157°E
Flow: 4 MLD approx.
The drain is unlined in the stretch before its confluence into Subarnarekha river. At this
location the river Subarnrekha is like a small stream having less flow of water in it and hence
it is more prone to pollution due to sewage or industrial effluent. The drain carries sewage of
Dhurwa locality which must be treated before discharging into the river. In-situ drain
treatment system (RENEU) of capacity 4 MLD may be provided for treatment of sewage
flowing through this drain. Site photograph of the drain is shown in Figure 4.
Approximate cost of the project would be 260 Lakhs including O&M for 5 year.
Approximate length of nallah where treatment system will be installed would be 200 meter.

4. Drain at Patel Nagar (Ward no. 52)
Location: 23.287955°N, 85.320537°E
Flow: 8 MLD approx.
The drain is unlined in the stretch before its confluence into Subarnarekha river. At this
location the river Subarnrekha is like a small stream having less flow of water in it and hence
it is more prone to pollution due to sewage or industrial effluent. The drain carries sewage of
nearby locality which must be treated before discharging into the river. In-situ drain treatment
system (RENEU) of capacity 8 MLD may be provided for treatment of sewage flowing
through this drain. Site photograph of the drain is shown in Figure 5.
Approximate cost of the project would be 430 Lakhs including O&M for 5 year.
Approximate length of nallah where treatment system will be installed would be 250 meter.

location the river Subarnrekha is like a small stream having less flow of water in it and hence
it is more prone to pollution due to sewage or industrial effluent. The drain carries sewage of
nearby locality which must be treated before discharging into the river. In-situ drain treatment
system (RENEU) of capacity 6 MLD may be provided for treatment of sewage flowing
through this drain. Site photograph of the drain is shown in Figure 6.
Approximate cost of the project would be 330 Lakhs including O&M for 5 year.
Approximate length of nallah where treatment system will be installed would be 220 meter.

RENEU Technology:
Restoration of Nallah with Ecological Units (RENEU) technology is a low cost In-situ drain
treatment technique developed by CSIR-NEERI. This treatment system can be installed in a
drain with minor civil work like construction of bed of drain and side walls etc. The system
includes screens and traps to remove floating debris, sedimentation unit for removal of
suspended solids, anaerobic and aerobic biodegradation by anoxic chamber and solar based
aeration respectively, use of defined bacterial consortia on biomats and biocurtains,
phytotraps as filteration unit, florafts for nutrients uptake and disinfection unit. Bacteria are
known to be biodegraders, possessing the genotype to utilize organics from wastewater as
their source of carbon and energy. They possess the unique property of horizontal gene
transfer that allows them to share target genes within the community and are hence natural
bioremediation agents. Plants have natural capacity for nutrient uptake and are also known to
immobilize inorganic pollutants. CSIR-NEERI has utilized these properties to engineer a
treatment process that includes biological methods along with physical processes like
sedimentation and screen traps for in-situ nallah treatment.
At present rivers, streams, lakes are getting contaminated due to mixing of untreated sewage
in most of the cities and towns in the country hence, there is an urgent need to develop
treatment strategies that will rejuvenate our water bodies and restore fresh water sources. The
conventional STPs take a long time to set up (typically two years), require skilled manpower
and are energy and resource intensive. Since the country is currently equipped with treatment
facility addressing only 30% of the waste generated, de- centralized treatment options may be
preferred option that will treat wastewater before it joins the rivers or lakes. RENEU is an
Enhanced Natural Attenuation process which is ecologically viable option that focuses on
clean up without disturbing the natural biodiversity and is cost effective as compared to
conventional STP systems.
The RENEU technology has been installed at many drains in the country and is found to be
effective to meet its intended purpose. The key highlights of the RENEU technology which
make it one of the robust and most sought after method for In-situ drain treatment may be
given as following:
• Sustainable method for In-situ wastewater treatment
• Less capital cost requirement
• Minimum operation and maintenance
• Provides better aesthetic appearance
• Proven technology which meets current discharge standards
• Less energy consumption
• Support for riparian and wetland vegetation.

Characteristics of raw sewage and treated effluent:
Treated effluent quality to a great extent depends upon raw sewage characteristics as well
besides the efficiency of treatment system installed. For the In-situ drain treatment using
RENEU technology it is expected that only municipal sewage would be entering into the
system and there would be no industrial wastewater. In case of industrial wastewater the
system may not be self-sufficient to meet the stringent discharge standards hence may require
additional treatment system. A typical wastewater characteristics of incoming sewage and
expected treated effluent quality is given in following table.

Site Visit and Feasibility Report for Adityapur (Jharkhand)
A team of CSIR-NEERI visited Adityapur (Jharkhand) on 05/03/2020 to see the current
status of sewage flowing through drains and possibility of installation of In-situ drain
treatment system (RENEU) developed by CSIR-NEERI for treatment of sewage flowing
through drains before its discharge into a natural stream. Kharkai River which is a tributary of
Subarnrekha River flows through the city. It is very necessary to treat the sewage before
discharging it into river Kharkai. The preset status of water quality is not good due to
discharge of untreated sewage into the river which further leads to reduced water quality in
Subarnrekha river as well. During the visit for the above said purpose, CSIR-NEERI team
was accompanied with officials from JUIDCO (Jharkhand Urban Infrastructure Development
Corporation) as well as officials from Adityapur ULB. Satellite view of Adityapur is shown
in Figure 1. A brief description of RENEU technology (Restoration of Nallah with Ecological
Units) is given as Annexure 1.

Location: 22.793280°N, 86.169309°E
Flow: 4 MLD approx.
The drain is unlined in the stretch before its confluence into Kharkai River. The flow in the
river is comparatively less and at same time depth of flow may also be nearly 0.5 m at the
above mentioned location. Hence at this location instead of providing In-situ drain treatment
system at separate drains it may be feasible to install some sort of treatment system which
may include florafts, aerators etc. at river itself. Site photograph of the drain is shown in
Figure 2.
Approximate cost of the project would be 180 Lakhs including O&M for 5 year.
Approximate length of river where treatment system will be installed would be 150 meter.

is nearly 200m away from JRDCL drain. The flow in the river is comparatively less and at
the same time depth of flow may also be nearly 0.5 m at the above mentioned location. Hence
at this location instead of providing In-situ drain treatment system at separate drains it may be
feasible to install some sort of treatment system in river itself which may include florafts,
aerators etc. Site photograph of the drain is shown in Figure 3.
Approximate cost of the project would be 220 Lakhs including O&M for 5 year.
Approximate length of river where treatment system will be installed would be 150 meter.

Flow: 7 MLD approx.
The drain is found unlined in the stretch before its confluence into Kharkai river. During the
visit it was observed that water quality was very poor in the river. Solid waste dumping was
also there on the banks of the river. At the given location instead of providing In-situ drain
treatment system at separate drain it may be feasible to install some sort of treatment system
in river itself which may include florafts, aerators etc. Site photograph of the drain is shown
in Figure 5.
Approximate cost of the project would be 280 Lakhs including O&M for 5 year.
Approximate length of river where treatment system will be installed would be 150 meter.

5. Saldih Drain:
Location: 22.797380°N, 86.161734°E
Flow: 2 MLD approx.
The drain is found unlined in the stretch before its confluence into Kharkai river. During the
visit it was observed that water quality was very poor in the river also the depth of flow was
less. Due to unavailability of suitable site for In-situ drain treatment system or Phytorid based
STP at the given location, it may be recommended to provide aerated lagoon or anaerobic
lagoon for treatment of sewage flowing through this drain. In addition to this it may also be
feasible to provide some sort of treatment system in river itself which may include florafts,
aerators etc. Site photograph of the drain is shown in Figure 6.
Approximate cost of the project would be 380 Lakhs including O&M for 5 year.
Approximate area of land required may be 500 square meter.

Site Visit and Feasibility Report for Jamshedpur (Jharkhand)
A team of CSIR-NEERI visited Jamshedpur city (Jharkhand) on 06/03/2020 to see the
current status of sewage flowing through drains and possibility of installation of In-situ drain
treatment system (RENEU) developed by CSIR-NEERI for treatment of sewage flowing
through drains before its discharge into a natural stream. Jamshedpur city, a famous steel
production hub is situated on the banks of Subarnrekha River. Kharkai River which is a
tributary of Subarnrekha River also flows adjacent to the city. In order to save our natural
water bodies, it is very necessary to treat the sewage flowing through drains before
discharging it into a river or stream. Sewage generated in Jamshedpur city through many
drains goes into river Subarnrekha. The present status of water quality in Subarnrekha River
is not good due to discharge of untreated sewage into it. During the visit for the above said
purpose, CSIR-NEERI team was accompanied with officials from JUIDCO (Jharkhand
Urban Infrastructure Development Corporation) as well as officials from Jamshedpur ULB.

includes screens and traps to remove floating debris, sedimentation unit for removal of
suspended solids, anaerobic and aerobic biodegradation by anoxic chamber and solar based
aeration respectively, use of defined bacterial consortia on biomats and biocurtains,
phytotraps as filteration unit, florafts for nutrients uptake and disinfection unit. Bacteria are
known to be biodegraders, possessing the genotype to utilize organics from wastewater as
their source of carbon and energy. They possess the unique property of horizontal gene
transfer that allows them to share target genes within the community and are hence natural
bioremediation agents. Plants have natural capacity for nutrient uptake and are also known to
immobilize inorganic pollutants. CSIR-NEERI has utilized these properties to engineer a
treatment process that includes biological methods along with physical processes like
sedimentation and screen traps for in-situ nallah treatment.
At present rivers, streams, lakes are getting contaminated due to mixing of untreated sewage
in most of the cities and towns in the country hence, there is an urgent need to develop
treatment strategies that will rejuvenate our water bodies and restore fresh water sources. The
conventional STPs take a long time to set up (typically two years), require skilled manpower
and are energy and resource intensive. Since the country is currently equipped with treatment
facility addressing only 30% of the waste generated, de- centralized treatment options may be
preferred option that will treat wastewater before it joins the rivers or lakes. RENEU is an
Enhanced Natural Attenuation process which is ecologically viable option that focuses on
clean up without disturbing the natural biodiversity and is cost effective as compared to
conventional STP systems.
The RENEU technology has been installed at many drains in the country and is found to be
effective to meet its intended purpose. The key highlights of the RENEU technology which
make it one of the robust and most sought after method for In-situ drain treatment may be
given as following:
• Sustainable method for In-situ wastewater treatment
• Less capital cost requirement
• Minimum operation and maintenance
• Provides better aesthetic appearance
• Proven technology which meets current discharge standards
• Less energy consumption
• Support for riparian and wetland vegetation.

Characteristics of raw sewage and treated effluent:
Treated effluent quality to a great extent depends upon raw sewage characteristics as well
besides the efficiency of treatment system installed. For the In-situ drain treatment using
RENEU technology it is expected that only municipal sewage would be entering into the
system and there would be no industrial wastewater. In case of industrial wastewater the
system may not be self-sufficient to meet the stringent discharge standards hence may require
additional treatment system. A typical wastewater characteristics of incoming sewage and
expected treated effluent quality is given in following table.

Site Visit and Feasibility Report for Mango (Jharkhand)
A team of CSIR-NEERI visited Mango municipality (Jharkhand) on 05/03/2020 to see the
current status of sewage flowing through drains and possibility of installation of In-situ drain
treatment system (RENEU) developed by CSIR-NEERI for treatment of sewage flowing
through drains before its discharge into a natural stream. Mango Municipal Corporation is
situated adjacent to Jamshedpur city on the bank of Subarnrekha River. It is very necessary to
treat the sewage flowing through drains before discharging it into river Subarnrekha. The
preset status of water quality is not good due to discharge of untreated sewage into the river.
During the visit for the above said purpose, CSIR-NEERI team was accompanied with
officials from JUIDCO (Jharkhand Urban Infrastructure Development Corporation) as well as
officials from Dhanbad ULB. Satellite view of Mango Municipal Corporation is shown in
Figure 1. A brief description of RENEU technology (Restoration of Nallah with Ecological
Units) and Phytorid technology are given as Annexure 1 and Annexure 2 respectively.
Fig. 1: Satellite view of Mango Municipal Corporation
The details of drains which were visited in Mango are given below.

1. Daiguttu Nallah:
Location: 22.820103°N, 86.206353°E
Flow: 8 MLD approx.
The drain is lined and close in the stretch before its confluence into Subarnarekha river. Solid
waste dumping was also observed at the point of confluence of drain into the river. In-situ
drain treatment system (RENEU) of capacity 8 MLD may be provided for treatment of
sewage flowing through this Nallah. Due to unavailability of sufficient straight length in the
direction of river, the drain may be further constructed parallel to the river for installation of
In-situ drain treatment system at this location. Site photograph of the drain is shown in Figure
2.
Approximate cost of the project would be 410 Lakhs including O&M for 5 year.
Approximate length of nallah where treatment system will be installed would be 250 meter.

2. Dimna Nallah:
Location: 22.820782°N, 86.237520°E
Flow: 10 MLD approx.
The drain is unlined and in the stretch before its confluence into Subarnrekha river.
Eutrophication in the drain was also observed due to stagnation of wastewater at the point of
confluence of drain into the river. Due to unavailability of suitable site for In-situ drain
treatment system (RENEU)/ Phytorid based STP, it may be recommended to provide SBR or
MBBR for treatment of sewage flowing through this Nallah. For this purpose first cleaning
and de-silting of Nallah will also be required. Site photograph of the drain is shown in Figure
2. Adequate security arrangements would also have to be made at the site as it is quite
remote.
Approximate cost of the project would be 2010 Lakhs including O&M for 5 year.
Approximate land area required where treatment system will be installed would be 800
square meter.

Annexure 2
Phytorid Technology for Sewage Treatment:
Phytorid based sewage treatment system is a low cost decentralised wastewater treatment
system developed by CSIR-NEERI. It employs natural method of wastewater treatment by
using constructed wetlands. It is a subsurface flow type system in which wastewater is
applied to a system filled with porous media such as crushed bricks, gravel and stones. In the
Phytorid bed some specific plants such as Elephant grass (Pennisetumpurpurem), Cattails
(Typha sp.), Reeds (Phragmitessp.), Cannas pp. and Yellow flag iris (Iris pseudocorus),
normally found in natural wetlands with filtration and treatment capability. Some ornamental
as well as flowering plants species such as Golden Dhuranda, Bamboo, Nerium, Colosia, etc.
can also be used for treatment as well as landscaping purposes. A typical flow scheme of
treatment units is shown in following Figure (a) and (b). Site photograph of a 1.5 MLD
capacity Phytorid based STP is shown in Figure (c).

vii CSIR- National Environmental Engineering Research Institute
Phytorid beds are provided for the removal of fine organic impurities from sewage. It utilises
natural treatment capacity of some specific plants in the form of constructed wetland. It
reduces BOD of incoming sewage in the range of 78 to 84%. It also removes nutrients like
nitrogen and phosphorus and removal efficiency varies in the range of 70 to 75% and 52 to
64% respectively. Tertiary treatment units like Activated Carbon Filter and Pressure Sand
Filter will also be provided to get better quality of treated effluent before discharging into the
pond. It removes leftover organic impurities, nutrients like Nitrogen and phosphorus and to
some extent toxic contaminants.

RENEU Technology:
Restoration of Nallah with Ecological Units (RENEU) technology is a low cost In-situ drain
treatment technique developed by CSIR-NEERI. This treatment system can be installed in a
drain with minor civil work like construction of bed of drain and side walls etc. The system
includes screens and traps to remove floating debris, sedimentation unit for removal of
suspended solids, anaerobic and aerobic biodegradation by anoxic chamber and solar based
aeration respectively, use of defined bacterial consortia on biomats and biocurtains,
phytotraps as filteration unit, florafts for nutrients uptake and disinfection unit. Bacteria are
known to be biodegraders, possessing the genotype to utilize organics from wastewater as
their source of carbon and energy. They possess the unique property of horizontal gene
transfer that allows them to share target genes within the community and are hence natural
bioremediation agents. Plants have natural capacity for nutrient uptake and are also known to
immobilize inorganic pollutants. CSIR-NEERI has utilized these properties to engineer a
treatment process that includes biological methods along with physical processes like
sedimentation and screen traps for in-situ nallah treatment.
At present rivers, streams, lakes are getting contaminated due to mixing of untreated sewage
in most of the cities and towns in the country hence, there is an urgent need to develop
treatment strategies that will rejuvenate our water bodies and restore fresh water sources. The
conventional STPs take a long time to set up (typically two years), require skilled manpower
and are energy and resource intensive. Since the country is currently equipped with treatment
facility addressing only 30% of the waste generated, de- centralized treatment options may be
preferred option that will treat wastewater before it joins the rivers or lakes. RENEU is an
Enhanced Natural Attenuation process which is ecologically viable option that focuses on
clean up without disturbing the natural biodiversity and is cost effective as compared to
conventional STP systems.
The RENEU technology has been installed at many drains in the country and is found to be
effective to meet its intended purpose. The key highlights of the RENEU technology which
make it one of the robust and most sought after method for In-situ drain treatment may be
given as following:
• Sustainable method for In-situ wastewater treatment
• Less capital cost requirement
• Minimum operation and maintenance
• Provides better aesthetic appearance
• Proven technology which meets current discharge standards
• Less energy consumption
• Support for riparian and wetland vegetation.

Treated effluent quality to a great extent depends upon raw sewage characteristics as well
besides the efficiency of treatment system installed. For the In-situ drain treatment using
RENEU technology it is expected that only municipal sewage would be entering into the
system and there would be no industrial wastewater. In case of industrial wastewater the
system may not be self-sufficient to meet the stringent discharge standards hence may require
additional treatment system. A typical wastewater characteristics of incoming sewage and
expected treated effluent quality is given in following table.

Annexure 2
Phytorid Technology for Sewage Treatment:
Phytorid based sewage treatment system is a low cost decentralised wastewater treatment
system developed by CSIR-NEERI. It employs natural method of wastewater treatment by
using constructed wetlands. It is a subsurface flow type system in which wastewater is
applied to a system filled with porous media such as crushed bricks, gravel and stones. In the
Phytorid bed some specific plants such as Elephant grass (Pennisetumpurpurem), Cattails
(Typha sp.), Reeds (Phragmitessp.), Cannas pp. and Yellow flag iris (Iris pseudocorus),
normally found in natural wetlands with filtration and treatment capability. Some ornamental
as well as flowering plants species such as Golden Dhuranda, Bamboo, Nerium, Colosia, etc.
can also be used for treatment as well as landscaping purposes. A typical flow scheme of
treatment units is shown in following Figure (a) and (b). Site photograph of a 1.5 MLD
capacity Phytorid based STP is shown in Figure (c).

Figure (c): Site Photograph of 1.5 MLD Capacity Sewage Treatment Plant Using Phytorid Technology
For treatment of wastewater using Phytorid based STP following units are generally provided
to treat the sewage in an efficient, economical & sustainable manner:
1. Screening
2. Collection in sump
3. Oil and Grease trap unit
4. Sedimentation tank / Anoxic chamber
5. Phytorid Beds
6. Tertiary treatment unit ACF and PSF
7. Chlorination unit
8. Final Discharge into receiving water body / reuse for irrigation, horticulture etc.
CSIR- National Environmental Engineering Research Institute vii
Phytorid beds are provided for the removal of fine organic impurities from sewage. It utilises
natural treatment capacity of some specific plants in the form of constructed wetland. It
reduces BOD of incoming sewage in the range of 78 to 84%. It also removes nutrients like
nitrogen and phosphorus and removal efficiency varies in the range of 70 to 75% and 52 to
64% respectively. Tertiary treatment units like Activated Carbon Filter and Pressure Sand
Filter will also be provided to get better quality of treated effluent before discharging into the
pond. It removes leftover organic impurities, nutrients like Nitrogen and phosphorus and to
some extent toxic contaminants.
Characteristics of raw sewage and treated effluent:
Treated effluent quality to a great extent depends upon raw sewage characteristics as well
besides the efficiency of treatment system installed. For the wastewater treatment using
Phytorid technology it is expected that only municipal sewage would be entering into the
system and there would be no industrial wastewater. In case of industrial wastewater the
system may not be self-sufficient to meet the stringent discharge standards hence may require

Annexure 1
RENEU Technology:
Restoration of Nallah with Ecological Units (RENEU) technology is a low cost In-situ drain
treatment technique developed by CSIR-NEERI. This treatment system can be installed in a
drain with minor civil work like construction of bed of drain and side walls etc. The system
includes screens and traps to remove floating debris, sedimentation unit for removal of
suspended solids, anaerobic and aerobic biodegradation by anoxic chamber and solar based
aeration respectively, use of defined bacterial consortia on biomats and biocurtains,
phytotraps as filteration unit, florafts for nutrients uptake and disinfection unit. Bacteria are
known to be biodegraders, possessing the genotype to utilize organics from wastewater as
their source of carbon and energy. They possess the unique property of horizontal gene
transfer that allows them to share target genes within the community and are hence natural
bioremediation agents. Plants have natural capacity for nutrient uptake and are also known to
immobilize inorganic pollutants. CSIR-NEERI has utilized these properties to engineer a
treatment process that includes biological methods along with physical processes like
sedimentation and screen traps for in-situ nallah treatment.
At present rivers, streams, lakes are getting contaminated due to mixing of untreated sewage
in most of the cities and towns in the country hence, there is an urgent need to develop
treatment strategies that will rejuvenate our water bodies and restore fresh water sources. The
conventional STPs take a long time to set up (typically two years), require skilled manpower
and are energy and resource intensive. Since the country is currently equipped with treatment
facility addressing only 30% of the waste generated, de- centralized treatment options may be
preferred option that will treat wastewater before it joins the rivers or lakes. RENEU is an
Enhanced Natural Attenuation process which is ecologically viable option that focuses on
clean up without disturbing the natural biodiversity and is cost effective as compared to
conventional STP systems.
The RENEU technology has been installed at many drains in the country and is found to be
effective to meet its intended purpose. The key highlights of the RENEU technology which
make it one of the robust and most sought after method for In-situ drain treatment may be
given as following:
• Sustainable method for In-situ wastewater treatment
• Less capital cost requirement
• Minimum operation and maintenance
• Provides better aesthetic appearance
• Proven technology which meets current discharge standards
• Less energy consumption
• Support for riparian and wetland vegetation.

Site Visit and Feasibility Report for Dhanbad (Jharkhand)
A team of CSIR-NEERI visited Dhanbad (Jharkhand) on 03/03/2020 to see the current status
of sewage flowing through drains and possibility of installation of In-situ drain treatment
system (RENEU) developed by CSIR-NEERI for treatment of sewage flowing through
drains. Damodar river which is a tributary of holy river Ganga flows adjacent to the city of
Dhanbad. It is very necessary to treat the sewage before discharging it into river Damodar.
During the visit for the above said purpose, CSIR-NEERI team was accompanied with
officials from JUIDCO (Jharkhand Urban Infrastructure Development Corporation) as well as
officials from Dhanbad ULB. Satellite view of Dhanbad is shown in Figure 1. A brief
description of RENEU technology (Restoration of Nallah with Ecological Units) is given as
Annexure 1.

1. Jeetpur Nallah:
Location: 23.716088°N, 86.394868°E
Flow: 30 MLD approx.
The drain is lined at some locations (may be upto 300 m or more at given location) and it is
found unlined in the stretch before its confluence into Damodar river. During the visit it was
observed that water quality was comparatively better in one drain whereas other drain
merging into Jeetpur nallah was carrying sewage of high turbidity and grey color. In-situ
drain treatment system (RENEU) of capacity 30 MLD may be provided for treatment of
sewage flowing through Jeetpur Nallah. Site photograph of the drain is shown in Figure 2.
Approximate cost of the project would be 750 Lakhs including O&M for 5 year.

2. Jodiya Nallah:
Location: 23.707441°N, 86.375843°E
Flow: 100 MLD approx.
The drain is found unlined in the stretch before its confluence into Damodar River. During
the visit it was observed that water quality was comparatively better in drain as the
wastewater travels nearly 10km through natural channel before joining Damodar River. In-
situ drain treatment system (RENEU) or other treatment system like Phytorid based STP will
not be feasible because of unavailability of suitable site and huge amount of flow. Hence in
order to treat the sewage of this drain separate STP may be recommended. As informed by
the officials of JUIDCO & Dhanbad ULB, an STP of 144 MLD capacity based on SBR
technology is at the planning stage so the sewage will be treated in that plant after
commissioning. Further the approach is to treat the sewage in the upstream itself where flow
in drain is limited and suitable site for set-up of the treatment system is available. Site
photograph of the drain is shown in Figure 3.

nallah at the above mentioned location. From this location wastewater travels nearly 25 kms
through natural channel before joining Damodar River. In-situ drain treatment system
(RENEU) or other treatment system like Phytorid based or conventional STP will not be
feasible because of unavailability of suitable site and huge amount of flow. Hence in order to
treat the sewage of this drain separate STP in a separate location along with I&D works may
be recommended. Site photograph of the drain is shown in Figure 8.

(8) Wasseypur Nallah:
Location: 23.793807°N, 86.415700°E
Flow: 30 MLD approx.
The drain is found unlined in the stretch at above mentioned location. Sewage flowing in the
drain from this location travels nearly 15 kms before its confluence into Damodar river.
During the visit it was observed that nallah was carrying sewage of high turbidity and grey
color. In-situ drain treatment system (RENEU) of capacity 30 MLD may be provided for
treatment of sewage flowing through this Nallah. Site photograph of the drain is shown in
Figure 9.
Approximate cost of the project would be 950 Lakhs including O&M for 5 year.
Approximate length of nallah where treatment system will be installed would be 400 meter.

Timeline for proposed work:
The proposed sewage treatment facility (RENEU) can be installed at site in three major steps.
(a) Site visit and collection of samples: the samples collected will be analysed for
various physico-chemical parameters like COD, BOD, pH, TDS, TSS, Phosphate,
Nitrate and Fecal Coliforms.
Duration: 1 month
(b) Preparation of DPR (Detailed Project Report): on the basis of primary data
collected at site viz. flow in the drain, characteristics of sewage samples, space
availability/ length of drain at site and topographical survey of site; a suitable
treatment system will be custom designed and accordingly cost estimates, relevant
drawings will be prepared.
Duration: 3 months
(c) Construction/ installation of treatment units: After the finalisation of DPR and
allotment of work order, actual execution of proposed work will be started at site.
Duration: 6 months
A brief description of timeline with respect to major activities under proposed work is given
in the following table.

RENEU Technology:
Restoration of Nallah with Ecological Units (RENEU) technology is a low cost In-situ drain
treatment technique developed by CSIR-NEERI. This treatment system can be installed in a
drain with minor civil work like construction of bed of drain and side walls etc. The system
includes screens and traps to remove floating debris, sedimentation unit for removal of
suspended solids, anaerobic and aerobic biodegradation by anoxic chamber and solar based
aeration respectively, use of defined bacterial consortia on biomats and biocurtains,
phytotraps as filteration unit, florafts for nutrients uptake and disinfection unit. Bacteria are
known to be biodegraders, possessing the genotype to utilize organics from wastewater as
their source of carbon and energy. They possess the unique property of horizontal gene
transfer that allows them to share target genes within the community and are hence natural
bioremediation agents. Plants have natural capacity for nutrient uptake and are also known to
immobilize inorganic pollutants. CSIR-NEERI has utilized these properties to engineer a
treatment process that includes biological methods along with physical processes like
sedimentation and screen traps for in-situ nallah treatment.
At present rivers, streams, lakes are getting contaminated due to mixing of untreated sewage
in most of the cities and towns in the country hence, there is an urgent need to develop
treatment strategies that will rejuvenate our water bodies and restore fresh water sources. The
conventional STPs take a long time to set up (typically two years), require skilled manpower
and are energy and resource intensive. Since the country is currently equipped with treatment
facility addressing only 30% of the waste generated, de- centralized treatment options may be
preferred option that will treat wastewater before it joins the rivers or lakes. RENEU is an
Enhanced Natural Attenuation process which is ecologically viable option that focuses on
clean up without disturbing the natural biodiversity and is cost effective as compared to
conventional STP systems.
The RENEU technology has been installed at many drains in the country and is found to be
effective to meet its intended purpose. The key highlights of the RENEU technology which
make it one of the robust and most sought after method for In-situ drain treatment may be
given as following:
• Sustainable method for In-situ wastewater treatment
• Less capital cost requirement
• Minimum operation and maintenance
• Provides better aesthetic appearance
• Proven technology which meets current discharge standards
• Less energy consumption
• Support for riparian and wetland vegetation.

Characteristics of raw sewage and treated effluent:
Treated effluent quality to a great extent depends upon raw sewage characteristics as well
besides the efficiency of treatment system installed. For the In-situ drain treatment using
RENEU technology it is expected that only municipal sewage would be entering into the
system and there would be no industrial wastewater. In case of industrial wastewater the
system may not be self-sufficient to meet the stringent discharge standards hence may require
additional treatment system. A typical wastewater characteristics of incoming sewage and
expected treated effluent quality is given in following table.
