CHAPTER 1
1.0 INTRODUCTION 1.1 Introduction
Kandy, the Capital of Hill country, situated in the Central Hill region of Sri Lanka was the last bastion of the Sinhala kings and is a charming city offering a living record of a magnificent past and a picturesque natural beauty to domain today. It has lot more to offer for the modern dwellers who find suitable place to live. It has its own peaceful, easygoing nature with its history, culture, forested hills and a touch of urban buzz. Situating only 115 km inland from the capital, climatically it is one of the most suitable places to live in due to its 500m altitude. It has superb education facilities for children and infra-structure facilities for adults. It is apparent that there is a big trend of immigration to Kandy and its suburbs from all over the island during the last few decades. Akurana, Poojapitiya, Harispattuwa, Gangawatakorale, Yatinuwara, Pathadumbara, Patha Hewaheta and Kundasale are the sub urban D S divisions bordering the city. (Refer Location Map-Figure 9.1) The higher education institutions such as University of Peradeniya, Co-operative Training School at Polgolla, Police Training School at Balagolla, Open University of Sri Lanka at Polgolla, Navel training base at Haragama, the advanced healthcare facilities through teaching hospitals with collaboration of the University, the proposed Cancer Hospital at Hantana road, the Eye hospital, the government institutions such as Ministry of Animal Production and Health, locating of the head office of the Agriculture Department are reasons for notably increasing immigration trends in these divisional secretariats. Furthermore it is now proposed to expand the city area by shifting the leading government and commercial institutes to Kundasale and Patha Hewaheta D.S Divisions to minimize the urban congestion and to allow room for increasing settlements and new development. Some of these are shifting the Central Provincial Council office to Pallekele, shifting army and naval bases to Pallekele area (in addition to its already established six camps), Upgrading of existing Police hospital, establishment of International Buddhist Centre and setting up the International Cricket ground. A domestic Air port, extension of Colombo Kandy highway to Kundasale are also been proposed to implement in the near future. All these development means attracting more and more people to Kandy and hence a rapid settlement process can be expected. This means a increase in water supply beyond its normal growth factors which certainly overgrow its present water supply capacity. Therefore, National Water Supply and Drainage Board (NWS&DB) and Kandy Municipal Council (KMC) have either to augment the present water facilities or implement new water supply projects to cater this growing demand. This report is a brief version of a comprehensive Master Plan prepared in order to enhance the water supply facilities in the divisional secretariats in the northern part of Kandy City namely Akurana, Pujapitiya, Harispattuwa, Patha Dumbara and Sections of Gangawata Korale & Thumpane. This consists of a solid water supply proposal to increase the existing water supply, to provide new extensions and to incorporate new service areas in the aforementioned area.

1.2 Authorization The NWS&DB has decided to speed up the Phase II of the Project Proposal by Greater Kandy Water Supply Project by introducing new proposal to be in pace with the rapidly growing demand in the area. His Excellency the President, Mahinda Rajapaksha implied his intension to complete these balance works on his official visit to the Water Treatment Plant (WTP) in July 2010 and further instructed to forward the details of financial requirements to the Treasury in order to arrange loan facilities. 1.3 Objectives and Scope The objective of this report is to formulate a Project Proposal to provide a 24-hour potable water supply to Northern part of Kandy City covering Six (6) Divisional Secretariats (DS) viz. Pathadumbara, Pujapitiya, Akurana, Harispattuwa and part of Gangawata Korale & Thumpane in the District of Kandy.
Identification of the demand-centers within the area that is not yet being served, strengthening of the existing level of service by improving the system, appraising of existing water supply systems, surveying of potential sources and the previous studies.
Scope of the Project: i) Construction of 2nd filter unit, 3rd clear water reservoir in Water Treatment Plant. (Plant capacity
will be improved to 100,000m3/day) ii) Construction of Service Reservoirs – 28 Nos. iii) Construction of Pumping Stations- 17 Nos. iv) Supply & laying of Transmission Pipelines - 86 km v) Supply & laying of Distribution Pipelines - 411 km vi) Construction of Quarters for NWS&DB staff vii) NRW reduction and Rehabilitation Programme.
1.4 General Description of Project Area & topography Proposed Kandy North water supply project covers the northern part of Kandy District which includes six (6) DS divisions viz. Pathadumbara, Pujapitiya, Akurana, Harispattuwa and part of Gangawata Korale and Thumpane.
Proposed Kandy North WSP is located in a mountainous region which spans over the northwestern part of the hill country of Sri Lanka. Kandy city centre is surrounded by a triangular mountain range while its three entrances located at each apex of the triangle and the other towards the valley on the eastern mountain range. Elevation of these entrances are approximately 450m in the north side (A10 road), 520m in the eastern side (A26 road), 580m southern side (B39 road) and 530m western direction (A1 road) respectively. The Meda Ela (Central Canal) originates from Kandy Lake spill and it flows southwestwards parallel to Colombo - Kandy Road (A1) and discharges into Mahaweli River at Getambe. Urbanization of the city is already commenced and is expanding towards the north, east and south entrances and has been developing southwestward along the Meda Ela. However the situation towards the north and north-western directions of the city is different, especially in Harispattuwa, Pujapitiya and Akurana DS areas located amongst a range of hills with considerable habitation. Ground Elevations of places such as Barigama, Medawala, Dunuwila, Jambugahapitiya and Doragamuwa areas exceed 600m MSL. Elevations of Locations such as Godahena, Ankumbura and Galhinna in Pujapitiya area reach 750m MSL. Distance to these hills from the Water Treatment Plant is approximately 10km, but the elevation difference is varies between 150m to 300m.

This is a peculiar situation which imposes restrictions on leading transmission mains and pumps. Although it is possible to use variable speed pumps in moderately sloping areas, in the case of Galhinna, Ankumbura and Godahena, it is not possible to use such variable speed pumps and the only alternative is to provide with fixed speed pumps.
1.5 Implementation of the Feasibility Study Rapidly increasing demand for potable water in Kandy city and suburbs has almost reached its supply capacity. Several studies have been carried out on improving water supply and sanitation facilities in the area during the last decade. The latest study was done by Japan International Cooperation Agency (JICA) in 1999. It focused on formulating a Water Supply and Sewerage Master Plan targeting up to the year of 2015 while review and complement the existing Water Supply Master Plan for identified Divisional secretariats in the Northern part of Kandy District and to conduct feasibility study for the priority areas identified in the Master Plan.
Above study was concluded in February 1999, with a long term development plan to be implemented in three phases for the planning horizon of 2015, Phase I to be completed in 2004, Phase II in 2008 and the Phase III in 2013. In 2005, new Master Plan reviews were conducted by the Master Plan Group, Grater Kandy Water Supply Project of NWSDB
Stage I of the Phase I of Greater Kandy Water Supply Project (GKWSP) was implemented with a loan package obtained from Japan Bank for International Cooperation (JBIC). Owing to financial constraints Project works with a reduced scope was commenced in early 2004 and was completed in October 2006. Construction work is in progress of stage II of the Phase I and due to be completed by end of 2012.
Since there had been a delay in implementing Phase I of GKWSP and also due to financial constraints, some development works identified in the Phase II and III of total Master Plan of GKWSP are presently being implemented with alternate funding sources for Udu/Yatinuwara, Kundasale and Haragama.
Water supply to some areas in Udunuwara and Yatinuwara DS Divisions were implemented under a separate foreign funded project called Kandy South Water Supply Project funded by Denmark. 1.6 Present Study for Kandy North Water Supply Project A preliminary review of the 2005 Master Plan Proposal was carried out in November 2011 by the Greater Kandy Project Monitoring Unit under the supervision Regional Support Centre (Central)of National Water Supply & Drainage Board. A full review of the proposal is underway at present.
• This study covers water supply facilities from water intake up to distribution reservoirs to meet the design capacity targeting year 2035. Planning of distribution pipelines was done on a hypothetical manner in previous Master Plan Study due to lack of data and information. Under the current study, all main roads, by roads, steps and foot paths have been included to the distribution network by using GPS instruments.
• Continuous water supply throughout the day shall be assured even during dry season so that the customers could avail a satisfactory water supply service.
• New supply systems shall be connected to the existing systems in order to minimize the project
cost for transmission / storage / distribution.

• 2010 Grama Niladari data , Vote register of consecutive years and census data of 2001 and 2011 were used to predict the growth rates.
• 2010 Grama Niladari population data with appropriate growth factors to suit the area concerned were used for demand calculation for the years 2015, 2020, 2025,2030 and 2035.
• An awareness programme and discussions were held with Grama Niladaris in each DS offices to
identify areas which need water supply. This was done through a two questionnaire surveys covering 5 DS divisions namely Pujapitiya, Pathadumbara, Akurana , Harispattuwa and Thumpane. Percentage of households not having safe drinking water at their premises 34 Percentage of households using unsafe drinking water 5 Percentage of households enjoying electrical power 94 Percentage of households receiving Samurdhi 31
Initial draft report of Kandy North Water Supply Project was send for PAC comments on 25.05.2012 Accordingly PAC has made following comments
1. Use new Census data for demand prediction and check the Migration factor 2. Breakdown the estimate for zonal basis and priority areas.
This report is revised as per the PAC comments.
1.7 Source of Supply The same source identified on Phase I of GKWSP, 4.1km upstream of the Polgolla barrage has been taken for the Kandy North Water Supply Project. An extensive hydrological study has been carried out in the previous Master Plan studies to ascertain the availability of the water and was found to be adequate.

CHAPTER 2
2.0 EXISTING WATER SUPPLY FACILITIES
2.1 Introduction 1) Rapidly increasing water demand in Kandy City and its suburbs has almost reached the situation of
exceeding its supply capacity.
Latest official results available on potable water facilities in Kandy North Project Area are as follows:
Pipe borne water - 45 % Protected wells - 38 % Unprotected wells - 3 % Tube wells - 4 % River /tank /stream etc - .05 %
Source : Statistics data 2011.
Existing Water Supply facilities in Kandy District are provided by following three major
institutions:
- Community Water Supply and Sanitation project (CWSSP) Funded by ADB Project - National Water Supply and Drainage Board - Provincial Council/Urban Council/Municipal Council
2.2 Schemes Operated Under Community Water Supply and Sanitation Project (CWSSP) Community Water Supply and Sanitation Project (CWSSP – II) was implemented under the Ministry of Urban Development and Water Supply to provide safe drinking water and enhance sanitation facilities among the rural communities since January 1999 to December 2003. The project was implemented along with Provincial Councils (PCs) and Pradeshiya Sabhas (PS) and provided improved water supply and sanitation facilities to 478 GN divisions in Central Provincial Council Area. Project objectives were implemented through Units set up at rural level and these units were guided by the Ministry of Urban Development and Water Supply. Non-governmental Organizations (Local) were deployed to assist the communities in setting up appropriate institutional mechanism i.e. Community Based Organizations (CBOs) at community level. Their responsibilities cover the areas such as dissemination of information, organizing of training, arrangements for hygiene education or conditions and supervision of construction and support for procurement of goods, services and operation & management of the scheme. Most of areas in Pujapitiya and Harispaththuwa DS divisions are highly benefitted by CWSSP activities. There are 20 schemes in Pujapitiya DS division and 7 schemes in Harispattuwa DS division were implemented under CWSSP. Details of these Scheme are given in Annex report chapter 2.

However, according to the water sample test results and the yield of water sources, it is perceptible that CWSSP schemes are not reliable in providing safe drinking water to cater to the increasing demands in the community. Further Studies are in progress to ascertain the feasibility of supplying bulk water from NWSDB to CWSSP schemes at a reasonable price to enable CBOO to operate the schemes independently.

2.3 Schemes operated under NWS&DB 2.3.1 Borehole Schemes: The existing borehole schemes are the first large scale water supply project in the Project Area which is done by FINNIDA aid under Government of Finland. Several borehole schemes were constructed in Kandy district under this project. According to respective Officers-In-Charge (OICs) of the schemes and geologists of NWSDB (RSC-Central), yield of a majority of boreholes as at present are depleting thus creating severe water shortages in the area. As a result, most of the boreholes had to be abandoned and at present only a few borehole schemes are functioning with a low yield. Table 2.2 -Present yield and No of connections of the Bore-hole Schemes

Ankumbura - 300 578 Alawatugoda 880 300 881 Galhinna - 80 368 Bokkawala 390 328 900 Hedeniya 1200 460 1285 Rajapihilla 680 200 2300
a) Ankumbura Water Supply Scheme The existing Ankumbura water supply scheme was designed and constructed in the year 1983. Two numbers of production boreholes are in use as the intake. Water is directly pumped to a 150 m3 capacity storage tank located at an elevation of 636 m MSL. It has the benefit of not requiring a full treatment process and it consists of an aerator, two slow sand filter units and a disinfection system. The water quality test reports indicate that the treatment works are in a satisfactory level. Surveys indicate that Ankumbura scheme covers 60% of the population in Ihalamulla, Egodamulla North and South, Pallegama North and South GN divisions. The scheme is capable of producing 300m3/day which serves 578 families. Another 150 families are in the waiting list, expecting to obtain new connections from the scheme.
b) Alawathugoda Water Supply Scheme (Owissa & Villana)
Alwatugoda water supply scheme was designed and constructed in 1983. Alawathugoda scheme is fed by two borehole intakes situated at Owissa and Vilana. There are two production boreholes at Owissa. During dry season water is obtained from a nearby stream. Water is pumped to the storage tank at 621 m above MSL by two pumps functioning at 30 m3/hr. rate through a booster pump station. There are two production boreholes in Vilana intake too. The water is pumped to a water tank at 618 m above MSL. Chlorine is mixed directly to the storage tank for disinfection. Alawathugoda scheme covers 65% of the population in Balakaduwa, Alwathugoda, Mawathupola, Arabepola, Delgasgoda GN divisions.
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 8
It is capable of serving 881 families with its daily production of 300m3/day. The level of service is not satisfactory.
c) Galhinna Water Supply Scheme
The existing Galihinna Water Supply Scheme was designed and constructed in 1983. The intake consists of two production boreholes. Water is directly pumped to the 150 m3 storage tank at a 743m above MSL. Chlorine is mixed directly to the storage tank for disinfection. Galhinna scheme is capable of covering 50% of the population in Galhinna, Kovil Muduna, Udagama GN divisions and serves about 368 families with its daily production of 80m3/day. This apparent people get water only for 2-3hrs per week under a zonal supply basis. At present overall level of supply of the scheme is not satisfactory. There are about 300 families willing to have new water connections by this scheme but the production is inadequate to fulfill their need. d) Bokkawala Water Supply Scheme
The existing Bokkawala water supply scheme was designed and constructed in the year 1987. Initially it has been planned for a production of 483 m3/day. The Bokkawala scheme has altogether four production boreholes, of which three located at Alagoda and one located at Dobagammana. Dobagammana borehole is having a yield of 128 m3/day while the Alagoda boreholes are having a yield of 200 m3/day. Water is pumped to a 300 m3 capacity storage tank at Nawinnapitiya at the elevation of 586m above MSL. The water is pumped at a rate of 8m3/hr per 16 hrs per day at Dombagammana and at a rate of 10 m3/hr. for 20 hrs. at Alagoda. Disinfection is done by Chlorination. Water quality is satisfactory in all aspects (physical, chemical and bacteriological) as per the test reports. Bokkawala scheme covers some parts of 18 GN divisions in the Pujapitiya DS. About 900 families are benefited at present by the scheme by its 328 m3/day production. Presently water supply is supplied under zonal basis and each zone gets water once in three days. The people in the higher elevations get water only once a week. There are about 863 families willing to obtain new water connections but the scheme is unable to fulfill the requirement due to the inadequacy of production.
e) Hedeniya Water Supply Scheme As all other Borehole schemes Hedeniya WSS also had been designed and constructed by FINNIDA and was implemented in the Year 1989. At the inception it had 5 borehole intakes at Madadeniya which had reduced to three active ones today. Water is fed from this intake to a 300m3 capacity storage reservoir at Madawala by Pujapitiya. The scheme is combined with shallow well intake at Bolagala . The water is fed by gravity to a 150m3 capacity storage reservoir at Bolagala without treatment. As the both reservoirs were located approximately at same elevation, a common distribution system is being shared. Even though the possibility of contamination is at a very high point at Bolagala intake due to adjacent paddy fields, the water is not being treated. Water quality reports prove the poor water quality. Presently most of the Bore-Hole schemes are beyond its design period and are in need of replacing with new source of water supply.
Some bore - hole schemes that have been already integrated by new large scale water treatment plants are tabulated below.

Polgolla Water Supply Scheme Current treatment plant capacity of the scheme is 9000m3/day and that serves 20,000 consumers. There is full treatment facility. Proposals are under way to increase the treatment capacity to 30,000m3/day. However this increase won’t be sufficient in catering the balance demand of 18,000m3/day predicted for 2027. Therefore the balance demand is proposed to be fed from separate project planned under Greater Kandy Water Supply Project at Katugastota. 2.3.3 New Large scale Water Supply Projects Operated under NWS &DB a. Greater Kandy Water Supply Project
Several studies have been carried out on improving water supply and sanitation facilities in the Kandy area during the last two decades, the latest of which is being done by Japan International Cooperation Agency (JICA) in 1999. This study focused on formulating a water supply and sewerage Master Plan up to the year of 2015. The above study was concluded in mid 1999, with a long term development plan to be implemented in three phases for the planning horizon of 2015, Phase I to be completed in 2004, Phase I in 2008 and Phase III in 2013. In year 2005 new master plan reviews was conducted by the Master plan section of Greater Kandy Water Supply Project. Phase I of Greater Kandy Water Supply Project (GKWSP) is being implemented with a loan fund from Japan Bank for International Cooperation (JBIC). Project works with a reduced scope due to financial constraints, commenced in early 2004 and has completed in October 2006 and Phase I Stage II construction work is in progress and constructions are due to be completed at the end of year 2012.
Since there had been a delay in implementing Phase I of GKWSP and also due to financial constraints, some development works identified in the master plan of GKWPS Phase II and Phase III are being implemented with alternate funding sources namely Udu/Yatinuwara, Kundasale and Haragama.
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 10
And some areas of Udu/ Yatinuwara were implemented under separate foreign funded project called Kandy South Water Supply Project funded by Denmark.
2.4 Schemes operated under Provincial Council/ Urban Council/ Municipal Council Some water supply schemes in the district are managed under local authorities such as KMC water supply scheme, Wattegama water supply scheme, Dambawela water supply scheme, etc. from which KMC water supply scheme lies within the proposed study area.
a. KMC Water Supply Scheme The oldest water supply system in Kandy District is Kandy Municipal Council system. This is the one and only local authority handled municipal water supply system in Sri Lanka. There about 150,000 urban consumers benefited by KMC system. Main source of water of the scheme is Mahaweli river where its intake and treatment plant located at Gatambe, some 3km southwards to Kandy town. The plant has 33,400 m3/day production capacity. R2 and R3 are the main reservoirs of KMC system. In addition to that there are reservoirs located at Dangolla, Bahirawakanda, Primrose and Periswatta. The water quality is satisfactory and it has its own full treatment plant. A water shearing policy has been adopted by KMC and NWS&DB after the implementation of Stage I of the Greater Kandy Water Supply Project in order to feed the areas of Ampitiya and Thennekumbura which is currently served by NWS&DB. Under Phase I Stage I of GKWSP Treated water is supplied to Asgiriya reservoir from Katugastota WTP and extract water to Ampitiya (5000m3/day) and Tennekumbura (2000m3/day) from R3 and R2 KMC reservoirs respectfully under this water sharing mechanism. 2.5 Current level of service 2.5.1 Borehole Scheme Currently about 50-60% of population of the served area is benefitted by the scheme. The number of households benefitted by boreholes schemes is given in the Table – 2-2. In general, the supply of all the borehole schemes is not satisfactory. In many of the schemes the water is supplied under zonal basis. There are schemes that supply water once in 2-5days. This situation becomes severe in dry seasons. In Galhinna Scheme there are zones that get water once in 10 days for only 2 hrs per day. 2.5.2 CWSSP Schemes It is observed that the supply is inadequate to feed the demand in almost all the schemes. Even the most simple treatment process-Chlorination was not utilized by the CBOO hence lowering the quality of water.
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 11
2.6 O&M setup and Billing and Collection 2.6.1 Borehole Schemes The NWS&DB is solely responsible for O&M of all borehole schemes in the area. Maintenance of some pump houses in Bokkawala and Hedeniya Schemes are being outsourced. Almost all the connections are metered at present. Spot billing on a monthly basis is taken place according to the metered consumption. Billing structure is as per the national tariff scheme (Refer www.Waterbord.lk). Regular disconnections programmes are in operation for overdue bills. 2.6.2 CWSSP Schemes Operation and Maintenance works are carried out by the village societies. Caretaker of the scheme is responsible for billing. Billing for the previous month is done at the beginning of preceding month and charges are being collected on the following day. Members have to pay according to tariff worked out for them by CWSSP before handing over the project for maintenance. All pipe replacement work or any repair work to be carried out by the CBO. 2.7 Water Quality 2.7.1 Borehole Schemes Physical, chemical and biological parameters of water in all the boreholes are satisfactory except in Hedeniya water supply scheme where a surface water system is being combined. 2.7.2 CWSSP Scheme Chlorination tank and mixing facilities are available. Sometimes dispute can be seen among villages regarding the chlorine mixing. Measured color and turbidity levels and biological parameters (total coli forms and Escherichia coli levels) are unsatisfactory in most of schemes. Ex. i. Dolapihilla ii. Owissa North. 2.8 Assessment & Recommendation 2.8.1 Borehole Schemes of NWS&DB Almost all borehole schemes are operating under capacity. This might leads to severe water shortages and health problems in future. It is the responsibility of NWS&DB to take immediate action to augment all these schemes under a sustainable and reliable water supply system. All borehole schemes in Kandy North Water Supply project area will be augmented and fed from Katugastota plant under KNWSP. 2.8.2 CWSSP Schemes
Government of Sri Lanka has already invested considerable funds for CWSSP schemes under ADB loans for Pujapitiya and Harispattuwa D S divisions. Therefore it is recommended to utilize the infra structures of these schemes (water tank, and distribution system) to get its optimum benefits. As sole authority to provide safe drinking water facilities to nation, the NWS&DB should prepare rules and regulations to manage the CWSSP system through the CBOO, NWS&DB being be the regulatory body. NWSDB must taken action to ensure the sustainability of the schemes either by augmenting the existing method of supply or feeding with bulk supply. The formalities, discussions and reviews have to be
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 12
arranged in order to convince the community, CWSSP, CBOs and Local authorities. The proposed Kandy North Water Supply Project is also designed after incorporating total demand of CWSSP schemes covered areas.

CHAPTER 3
3.0 HEALTH AND SANITATION 3.1 Health
Sources of Drinking water fed to area covered under proposed Kandy North Supply Project includes boreholes maintained by NWS&DB, dug-wells done by CWSSP, fully treated water from NWSDB treatment plants, treated water from KMC treatment plant, shallow wells and springs, streams, tube wells etc.
Studies indicate that CWSSP schemes which mostly use water from shallow wells and streams as the source of supply and the NWSDB maintained some borehole WSSs do not satisfy Sri Lankan standards for drinking water and subsequently could cause health problems.
Following tables depict the water born disease records of the six DS divisions covered by Kandy-North Proposal. It confirms that water born diseases have not reached an epidemic situation.
Table 3.1 refers to year 2006 statistical data available at the General Hospital Kandy, for the Kandy Municipal area. A considerable number of patients infected by water born diseases have been recorded in year 2006 and the number has been decreased in next year's. It can be attributed to the enhanced quality of drinking water made available by the commissioning of Phase I Stage I of Greater Kandy Water Supply Project in October 2006.
Prior to implementing of phase I stage I of GKWSP, KMC supply had to be restricted to two days per week on zonal basis in certain sections of the area. But after the implementation, KMC receives a bulk supply from NWSDB, enabling KMC population to enjoy 100% coverage and 24 hrs uninterrupted water supply improving the sanitation conditions of the community.

According to the MOH officials’ (Refer Table 3.2) data, water born diseases still prevail in semi Urban DS divisions such as Harispattuwa, Akurana, and Pathadumbara adjacent to Kandy Municipal limits. It can be assumed this is may be due to non availability of 100% NWS&DB water supply for these areas. It

3.2 Sanitation Sanitary facilities available for the people of Kandy district is at a high level when compared to that of the national data. Records indicate that only 5% do not have proper sanitation facilities in the district. 3.3 Garbage and Sewerage Disposal Kandy Municipal Council and the surrounding local authorities use a location at Tekkawatta in Gohagoda GN Division of Harispattuwa electorate as their garbage dumping yard. It is observed that it infiltrates to Mahaweli River during the rainy season. To solve this problem KMC has initiated the City Garbage Management Project. Meda-Ela is a canal passing through Kandy City parallel to Peradeniya-Kandy road which originates at the spillway of Kandy Lake and falls into Mahaweli River just above the KMC intake. This stream gets polluted as the people and the institutions in the proximity release their sewerage and wastewater directly to the canal and ultimately it discharges to Mahaweli. In order to overcome this problem NWS&DB and KMC jointly implement the Kandy City Sewerage project. Planning and basic designing work of this sewerage project is complete and Tenders have been called. The project is scheduled to be completed by year 2018. Sewage and garbage disposal of other rural and semi-urban areas has not reached an alarming level and respective local authorities handle the waste disposal system in their own areas. In addition most of the rural communities dispose or burn their garbage at their own premises.

CHAPTER 4
4.0 ENVIRONMENTAL ASPECTS 4.1 Introduction In general, the project is conducive to the environment, giving a substantial contribution towards the improvement of water quality in the project area, with all consequent positive effects on public health, general socioeconomic development and visual impact. Although no permanent negative effects are anticipated by this project, some critical environmental aspects which will deserve an attentive environmental management may arise during the construction or operation stage and should take appropriate steps to avoid nuisance to public. 4.2 Legal Requirement for EIA The Environmental studies carried out under the present project include; An Initial Environmental Examination (IEE), carried out by the JICA mission during the first phase of the project (February - April 1998). An Environmental Impact Assessment (EIA) executed with the help of a subcontracted local consultant, during the second stage of the project, between August to November 1998; A water, sewerage and sludge quality survey, carried out by means of two separate field campaigns, respectively performed during the dry season (February - March, 1998) and during the rainy seasons (July - August, 1998). The IEE, completed in April 1998, was submitted for approval of NWS&DB, and the Central Environmental Authority (CEA) of Sri Lanka, which is the statutory government Agency, empowered for environmental licensing in the country. The CEA, after reviewing the IEE and considering the size and the characterization of the different project components, categorized this project as not prescribed under the gazette Extra Ordinary no 722/22 dated 24th June 1993, meaning that the project implementing agency (NWS&DB) has no obligations to submit an EIA to the Central Environmental Authority (CEA) for the licensing of the present project. Nevertheless, CEA proposed a certain number of recommendations which imposed a deeper environmental analysis, and the NWSDB officially requested the JICA study team to execute a full scale EIA, as initially planned. As mentioned in CEA conditions to implement the Greater Kandy Water Supply Project, following safety and environmental measures will also be followed during implementation period of Kandy North Project which has already been followed during Phase I Stage I and Stage II.

4.3 Safety and Environment Measures a) Disposal of Waste and Excavated Materials Phase I Stage I of Greater Kandy Water Supply Project has already been completed and Phase I Stage II constructions are in progress at present. GKWSP who is responsible in preparation of this report is strictly concerned over the proper disposal of waste and excavated material from pipe laying and reservoir sites. PMU of GKWSP has strictly advised the contractors to ensure proper disposal of excavated material and the contractors should get the approval of the respective local authorities for using dumping yards. PMU and the consultant supposed to investigate any social or environmental impacts created by these dumping yard. In addition, special conditions too are included in the contract document to ensure this fact. Ex: All excavated material should be transported to the dumping yard within excavated day itself.
b) Solid Waste Disposal Solid waste associated with the work force must also be collected and sent either to garbage collection location or set fire on site. In addition, all contractors are instructed to submit weekly site cleaning and mosquito breeding prevention report regularly. c) Transport of Materials And Equipment Most of the construction sites under Kandy North proposal are located in rural areas of Kandy District. Hence severe traffic congestion is not expected. Since excavated material, impacted soil, sand, quarry dust, ABC are generally transported in 1-2 cube capacity tippers, damage to roads by these vehicles are minimized. All damages caused by pipe laying (pipe trench side and other side) along the roads and alternative roads will be repaired at Project cost to minimize the social and environmental impact. d) Noise Control Construction activities that create noise will not be permitted to be conducted in the night. Controlled rock blasting will not be allowed in high sensitive areas and chemical blasting is encouraged. Blasting work during night is entirely restricted.
4.4 Impact of Water Abstraction from the Mahaweli River Total anticipated water abstraction at the existing intake will be 150,000 m3/d when the project complete, and this will have a direct impact on the overall water availability at Polgolla reservoir. This will affect water users for power generation and agriculture. (Water is diverted from Polgolla reservoir). On average, the percentage of abstraction for water supply from the Mahaweli River at Polgolla reservoir is 2.85% of the total inflow. Assuming that 50% of abstraction returns back to the river, the actual water loss to the system will not exceed 1.43% of available water, and is therefore considered negligible. According to statistical analysis of available data, daily inflows are less than the anticipated abstraction with a probability ranging from 5% of the time (daily low flows) to 13%. Minor impacts may be expected on energy generation and agriculture, both based on water being diverted at Polgolla dam. Formal agreements must be reached between the NWS&DB with the Mahaweli Authority of Sri Lanka (MASL), on how to share the use of water in case of conflict (sought years), before the completion of the
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 17
project., in addition to the current agreement of getting 180,000 m³/day., to Greater Kandy Plant from Mahaweli River - (Refer Annex-4 - Agreement Letter)
4.5 Water Quality Assessment and Balance of Contamination in the Major Surface Water Bodies in the Project Area
I. Water Quality Survey
Comprehensive water, sewerage and sludge quality survey was carried out by the JICA study Team during the Master plan preparation. Quality of surface and ground water (e.g., raw water, river, water, water from bore holes and lake) was examined during dry weather (February- march 1998), and during wet weather (July- August 1998),at several pre- selected sites. Physico-chemical parameters, trace metals bacteriological (Coliform and Ecoli) and pesticides have been determined. Main water bodies in the project area (Mahaweli River, Meda Ela Kandy Lake and Pinga Oya ) show high levels of contamination due to the release of garbage. Extremely high concentrations of nitrogen have been reported in the Mahaweli River and its distribution channels. Further high concentration of zinc and iron was found in Mahaweli River, Meda Ela and the Kandy Lake.
II. Contaminations and project impacts on water quality
Project impacts on Kandy Lake, Meda Ela and the Mahaweli river have been quantified using a water quality modeling. Biological Oxygen Demand (BOD5), Dissolved Oxygen (DO),total nitrogen (T-N)and total phosphorous (T-P)have been considered a leading contaminants. Concentrations in Kandy Lake had been one – dimensional (Linear) modeling approach, The concentration in Kandy Lake was measured through a one dimensional (lineal modeling approach) 4.6 Other Impact I. Noise Sri Lanka regulations about noise control are established by Ministry of Transport, Environment and Women’s affairs, under Section 23P and 23R of the National environmental Act, No.47 of 1980. In general, the maximum permissible noise levels at boundaries of the construction area is fixed at 75 dB during day time, and 50dB during night time (NEA, schedule III, Regulation 4). Sensitive areas include during construction are the same reported above, but maximum time of exposure must be reduced. To avoid public nuisance and repeated interruption to work, population and the surrounding communities should be adequately notified. 4.7. Constructions and Pipe laying in Hantana Environmental Protection area. Pipe laying in Hantana area under Kandy North Proposal will be within the area declared as "Hantana Environmental Protection Area”, by the ministry of environment and Natural Resources, under section 24C and section 24D of the National Environmental Act No.47 of 1980, under part I (section (I)) - General, of the extraordinary Government Notifications dated 17.02.2010, issued under the gazette of the Democratic socialist republic of Sri Lanka. Hence, special approval has to be obtained from relevant authorities of Ministry of Environment and Natural Resources prior to commencement of pipe laying work in this area.

CHAPTER 5
5.0 SOCIO-ECONOMIC CONDITIONS, COVERAGE FACTOR AND POTENTIAL DEVELOPMENT TRENDS OF THE KANDY NORTH PROJECT AREA 5.1 Socio-Economic studies
Introduction The main objective of socio - economic studies are identification and evaluation of the socio-economic status in the area in order to obtain essential planning information for project formulation proposals. Further, the process would ensure sustainable infrastructure development within the area with reasonable and justifiable economic benefits. Hence two socio - economic and demographic surveys (SEDS) were carried out for this proposal. Based on first 1st socio-economic survey findings, second Socio-economic survey was conducted covering 25% of total population in 4 DS divisions namely Akurana, Pujapitiya, Pathadumbara and Harispattuwa.
5.2 Social profile of the project area
The Kandy North Water Supply project area consists of 455 GN divisions which include 6 DS divisions in Kandy district in Central province. Those DS divisions are Harispattuwa, Pujapitiya, Akurana, Pathadumbara, part of Kandy Four Gravest, and part of Thumpane. According to the predicted population, the total number of people who would benefit from the proposed integrated water supply system would be approximately 450,000 by the year of 2035.
Average family size The average family size was 4.6 from the findings of the sample survey. These figures are mostly in accordance with the national level statistics and DS divisional data which were collected through AD planning officers of each Divisional Secretariat in the project area. Migration and period of settlement Settlement habitation pattern has a direct concern on water supply planning. It is found that, 72 % of the total sample is long term residents of the area since their birth and 28 % of the population have migrated and settled down in the area due to various other reasons.

Reference to table 5.4 it is shown that overall situation of the area covered by the study, it is evident that a considerable number of dug wells are available in the area as sources of domestic water supplies. Most of them are having water in shallow depths and water table fluctuations during the dry periods are marginal.

According to the overall assessment, about 18.5% are using unprotected water sources for drinking, cooking, washing and bathing. This might be considered as an alarming situation in respect to community health. Further, a substantial number of household are compelled to use springs and streams as their secondary water source during the drought periods when their primary source has limitations. However the users have a feeling that around 63% percent of their current water sources are quit reliable in the context of domestic supplies irrespective of the water quality and distance to the source.
The following observations were made during the field surveys in respect of user satisfaction on available pipe water supplies in the area maintained by NWS&DB/PSS/CBO's.
• All people have shown their dissatisfaction regarding supply hours, water quality, operation and maintenance and water availability of all pipe borne water supplies.
• Majority of poor people in the existing service area are facing critical problems during drought period. They depend upon bowser supplies, transport water from faraway places or some other alternative arrangements for domestic water.
5.3.2 Water Quality (user views)
In accordance with user views, they believe that water qualities of most of the water sources in the area are acceptable in respect to the physical parameters and hence safe for drinking. As compared to dry zone districts, chemical water quality problems are scarce in this area. However user perception on water quality at some pipe water supply systems has been reported unsatisfactory.
5.4 Water carrying and current usage patterns
5.4.1 Distance to the sources and the time spent for fetching water
Table 5.5 - time spent for fetching water
Distance to the sources and time spent for fetching water has been evaluated based on the user views in order to ascertain the hardships faced by the users in their day to day life. According to the findings of the house hold survey approximately 21.2 % of the sample populations are having problems with distance to the sources and duration for water carrying. During the drought period some of the water sources dries up and the situation become worse. Therefore the time spent for carrying water is dependent on the availability of water at their primary sources. Refer Table 5.5.

Current expenditure on water supply facilities vs. affordability
There are several problems in the drinking water facilities within the area. Hence, people tend to spend more money to obtain their requirements of water especially during the dry season. They spend money for water carrying and water transportation. Medium income groups and high income groups use their own vehicles to find water for drinking purposes and domestic purposes spending considerable amount of money for fuel. However, the low-income groups mainly depend upon their own methods to collect water in dry season. Mostly, they collect water utilizing their family labor. According to the above reasons patterns of usage of drinking water in dry seasons are more related to the level of poverty in the area. Most of the poorest community rather than better income and medium income community are facing more difficulties to find water in dry season. If there is an improved water supply, the majority of the households have a potential to pay a reasonable amount for their services, since the demand is extremely high in dry season.
Cost incurred based on distance and time, on the assumption that a sum of 60 Rs per hour per head for fetching water. So, Cost for carrying water per month from well = Rs. 2,367.00
5.7 User preference for mode of operation and management
5.7.1 Preferred mode of O&M of water supply scheme
Long-term sustainability of a pipe borne water supply scheme would be governed by several technical, institutional and financial parameters, among which a proper operation and maintenance system would play a vital role. Hence selection of an appropriate and capable maintenance authority would be an absolute need. Apart from the technical and institutional capabilities, consumer preferences or their choice on the selection of a maintenance authority have been seriously considered under the study.
Hence, due consideration has been given during the feasibility studies to obtain beneficiary views on their selection of a maintenance authority. Around 79.6 % of the people have given their consent to select NWS&DB as the maintenance authority. Only 2.2 % of the sample population has shown their agreement on selecting the Local Authority as the maintenance party. A very low percentage of people prefer the Local Authority and NWS&DB joint maintenance mode, but 8.0% of the community prefers CBO and NWS&DB joint maintenance system. It is important that community presumed that they themselves would have some authority in maintenance of their water supply systems.
People need good quality water for domestic purposes at a reasonable cost. At present, people within the area greatly suffer due to a lack of quantity and quality of water (even in the present water supply Schemes) specially maintained by Local Authority or CBO. People within the area are confident that NWS&DB could handle the situation in a more professional manner than the other authorities.

CHAPTER 6
6.0 TECHNICAL ASPECTS 6.1 Determination of Water Requirement 6.1.1. Identification of Project area Kandy North project area covers the northern part of the Kandy district which includes 6 DS divisions viz. Pathadumbara, Pujapitiya, Akurana, Harispattuwa and Sections of Gangawata Korale & Thumpane which covers 318 km2 of area. The city of Kandy lies at an altitude of 500 meters above sea level in the center of the island and surrounded by the ranges of mountains. Kandy, the Capital of Hill country, situated in the Central Hill region of Sri Lanka was the last bastion of the Sinhala kings and is a charming city offering a living record of a magnificent past and a picturesque natural beauty to domain today. It has lot more to offer for the modern dwellers who find suitable place to live. It has its own peaceful, easygoing nature with its history, culture, forested hills and a touch of urban buzz. Situating only 115 km inland from the capital, climatically it is one of the most suitable places to live. Kandy has now grown out to encompass Peradeniya, from southern direction to the University of Peradeniya and the Botanical Gardens, Katugastota, to the north, and east to Kundasale, Tennekumbura and Gurudeniya. Akurana, Harispattuwa, Pujapitiya, Thumpane and Pathadumbara are the adjacent Divisional Secretariats that lie in the north and northwestern parts of Kandy. Proposed Kandy North water supply scheme covers the northern part of Kandy District which includes six (6) DS divisions viz. Pathadumbara, Pujapitiya, Akurana, Harispattuwa and Sections of Gangawata Korale & Thumpane. These Divisional Secretariats considered as remote and rural areas about 2-3 decades ago. With the rapid expansion of population associated with rural industries and other economic activities along with saturation of settlements in Kandy City and suburbs, these areas have become residential. The forest cover, the extent of home gardens and plantations are gradually diminishing and the resource bases for the most essential commodities, especially water, in the area are becoming scarce. Most of the shallow wells which existed for many decades in Pathadumbara area have run dry as a consequence of construction of Polgolla Tunnel under Mahaweli Development Project. Furthermore, village expansion programmes implemented by successive governments as a measure of poverty alleviation and in order to compensate the inundated lands in Mahaweli Development Plan, have been extended to higher elevated areas due to lack of lands with reasonable facilities. Meanwhile, the people who have settled down under such schemes encounterd many hardships in finding drinking water since there is no source of water in these hilly terrains. Pathadumbara lies east to the Kandy Municipality which includes small towns of Polgolla, Madawala and Wattegama. Many prominent Government Institutions namely, Provincial Center of the Open University of Sri Lanka, Faculty of the Rajarata University, Teachers’ Training School, Cooperative Training School and other industrial organizations are established in this area. It is evident that the population density in the project area would rapidly increase with the implementation of Katuagastota - Kurunegala main road and the proposed Colombo - Kandy new highway tracing through the northern boundary of the project area. Adequate water supply and good sanitation practices are of vital important in leading a healthy life and to perform the day to day activities timely and efficiently. Many water borne deceases prevail in the society are due to lack of safe drinking water and good sanitation practices.

6.1.2 Determination of Served Area Service reservoirs were identified on suitable high grounds in order to cater the maximum possible population in the area, giving due attention to the following basic criteria.
i) Maximum pressure head of a service reservoir is 60 m ii) Economical transmission cost iii) Economical distribution cost iv) Economical energy cost v) Minimum O & M cost
Extents of the service zones were determined according to the Grama Niladhari Divisions which can be served under the service reservoir. Some service zones were extended beyond the maximum pressure head of 60m due to non availability of nearby reservoirs or towards low elevated locations by means of pressure reducing valves. 6.1.3 Assessment of Growth Rates Following data were used in predicting future population supposed to be served. • Population data from Census of Population and Housing – 2001 and 2012 • Population data collected by the survey carried out by the Greater Kandy Water Supply Project based
on Grama Niladhari Divisions. • Statistics of Elections Department - Number of registered voters on electoral division basis. • Population data collected from Divisional Secretariats. a) Current Population 2010 Grama Niladari population data were used as the base population in this planning process and the information given by the Elections Department and 2001 and 2012 Census Data were utilized to determine the population growth rate. This is compared with the projection given in JICA study team based on the estimation given for DS areas.
b) Annual Growth Rate To predict the growth rate of each DS division, the present and future development trends were studied in each area together with migration trends (ex:- Kandy Colombo highway) etc. The available data sources such as statistics of the registered voters in electoral divisions and the population density of the G.N. divisions were also used to identify the growth pattern of the population. c) Growth rate justification According to the population densities of the D.S. divisions of the Kandy District, it is observed that the D.S. divisions falling under the command area of the Kandy North project area has a higher population density than the rest (refer Table 6.1 and Table 6.2)

Nsg 27
Table 6.1 - Population density of the Kandy North Project Area.
Table 6.2 - Population density of the other DS divisions in Kandy district
As per the new government education policy which is still in review stage it is proposed that the primary sections of all leading schools in cities will be shifted to suburbs of the cities. In case this takes effect, migration of population will be increased in suburbs cities near to Kandy city. Further it is justified that the above assumption are realistic, based on the growth pattern of the registered voters of the D.S. divisions. Average growth rate of voters according to the electoral divisions relevant to D.S. divisions considering the statistics available for the period of 1998 - 2009 are given in Table 6.3.

Table 6.3 - (b) Average Growth Rate in the Project area
Source: Census 2011 and 2001-Census Department According to the Table 6.3 (a) and (b) growth rates of some DS divisions are slightly deferent. Future growth rates are predicted based on above two table and current and future trends of each DS division. Growth justification of each D.S division is discussed below. a. Akurana
Akurana is the D.S. division having the highest population density in the Harispattuwa electorate. It is located along the Kandy - Jaffna road and is the most developed and urbanized area of the Harispattuwa electorate. Also there is an existing water supply scheme operated and maintained under NWS&DB. Presently there are large number applicants in waiting list for water supply but unable to cater from the existing system. According to the current development pattern, especially as a commercial city, there is a trend for migration inwards. Current population growth rate of Akurana is about 1.34% as per the early updated 2011 census data. High growth rate and migration trend can be expected after receiving water to Akurana area as per the previous experience of Phase I Stage I of Greater Kandy Water Supply Project. Therefore, 1.3% initial growth rate up to 2015 and then growth rate decreases to meet the national figures. Refer Table 6.3

Nsg 29
b. Harispattuwa
Harispattuwa D.S. division has a considerable population density when compared with the other D.S. divisions of the district. This area consists with a good road network. Also the proposed Colombo - Kandy Highway mark out across the Harispattuwa D.S. division. Triangle of minor cities namely Gohagoda, Katugastota and Barigama are enclosed by three main roads. Therefore, the area will be attracted by the migrants as a suburban area of the Kandy city and a continuous economical and social development of the area can be expected. Current population growth rate for the area as per census data is 1.08%. However, considering the topography and other land limitations in the area a flat growth rate of 1.05% used for this division up to 2015. Then that growth rate further reduced. Refer Table 6.5. c. Poojapitiya Pujapitiya Divisional secretariat is having a low growth rate compared to adjacent Harispattuwa and Akurana, D.S. divisions. It can be assumed that Pujapitiya also would get the same trend in development as a residential area by replicating the migration pattern of Harispattuwa and Akurana. This development can be further influenced by the implementation of the water supply project. The small towns in the area namely Madawala, Poojapitiya and Bokkawala will be developed in future. According to the Census data 2011, current population growth rate is 0.6%. However considering the geographical location (hilly terrain) of this area and its remoteness may not attract migrating population and therefore a larger population settlement cannot be expected in this division. Hence low growth rate was adopted. Refer Table 6.5 d. Pathadumbara In Pathadumbara D.S division, population density is considerably high and there are no sufficient water supply facilities available in the area. Percentage of served population with available water facilities according to the total demand indicates a lower value of about 25%. Current population growth rate according to the census data is 0.9%. However Pathadumbara is one of adjacent area of Kandy Municipality consisting small towns Polgolla, Madawala and Wattegama urban areas. Also it has convenient access to Kandy through Wattegama- Matale road. Wattegama is an old town council bordering the railway station and supports a large population with many economic activities. There are many government institutions located in the area namely, Provincial centers of the Open University of Sri Lanka, Faculty of Rajarata University, Teachers’ Training school, Cooperative Training school and many other industrial organizations. Therefore it is envisaged a possibility of further increase of growth rate with the new water supply facility as there is a significantly high demand for water. This growth rate can be reached to a saturated level with the increase of the population density. Considering the above facts, growth rate of 0.9 % assumed up to year 2015 and 0.8 % flat growth rate is adopted after 2025. Refer Table 6.5

Nsg 30
e. Kandy Four Gravets
The administrative area of the Kandy Four Gravets covers the Kandy Municipality area and urbanized suburb areas. At present, D.S. division of Kandy Four Gravets indicates the highest population density within the Kandy District. As the second biggest city of Sri Lanka having a great historical value, a higher development can be expected in the Kandy City and suburbs. There are lands available in higher elevations of the city which is attracted by the migrants and investors due to the panoramic view. But most of those areas do not have adequate water supply facilities. Considering the topography and migration in the area of flat growth rate of 1.3% is used. However, southern part of this division especially the adjoining area of the KMC, like Heerassagala and Hantana, there is high potential for migrants. A special approach is adopted to project the population of this area as follows. The computation was done by selecting a cluster of Grama Niladhari Divisions from the heart of Kandy City having a higher population density. The new projected population and demand of 7 Nos. reservoirs were computed and given below.

6.1.4 Coverage Factor
Coverage factor shows the percentage of houses that will take house connections from total available houses in an area. Generally coverage factor is found from social economic surveys which are carried out during the design stage of new water supply projects. Here also coverage factor was obtained through 2nd socio economic survey (Gramaniladari survey) and following coverage factors are calculated. Practically coverage factor cannot be calculated only through the Demographics Surveys. Coverage factor depends on willingness to pay for water, ability to pay for water (income and water tariff), the quality / quantity and easy access of the existing water sources etc.
Table 6.6 - Coverage Factor 6.1.5 NRW percentage Kandy North Water Supply Project area is covered with number of existing water supply schemes. Some schemes are having with high NRW percentage. NWSDB is already implemented various NRW reduction programme to reduce the NRW percentage to reasonable level. Under Kandy North Project considerable amount of funds are allocated to above programme. Therefore, following NRW percentage are assumed in future for water demand projection.

6.2.2 Ground Water Sources In the area covered by the Kandy North proposal, the cover of overburden is relatively thin and therefore there is a good prospect of finding groundwater resources in rock masses, which are joined, fractured and possibly weathered. Such rock masses comprising of quartzite, limestone and calc-gneiss bands provide a very good yield. However, the current data on the groundwater availability at various locations in the Kandy district is very sketchy, and therefore it is not possible to qualify the capacity, and the corresponding sustainable yield of aquifers. Fifteen water supply schemes in Harispattuwa, Akurana and Pujapitiya DS Divisions are fed by ground water from boreholes only, and two more are fed by combination of boreholes and surface water sources. These were originally built as rural systems to serve small communities in certain specific localities, where ground water could be found in adequate quantities after early investigations. Most of these schemes are currently malfunctioning due to the wells having low yield-less than 1000 m3/d, and some are even worse with several hundred cubic meters per day, whilst some are yielding hard water exceeding the maximum desirable level of 500 mg/l (though below the maximum permissible level of 600 mg/l). Some of these wells contain a high iron content rendering the water unsuitable for drinking and washing (refer Annex 2.3 of annexes report, water quality of existing borehole systems). Furthermore, yield of many of these wells is unreliable as it depletes during demand. The mismatching of the well design and pump specifications at low yields further aggravates this situation. Due to the wells extracting ground water from aquifers above the bedrock layer they become vulnerable during the dry seasons. Such factors will produce a low service level. At places like Ampitiya and Gohagoda, the boreholes cause the lowering of the ground water table in the nearby area, affecting the paddy fields and shallow wells. Boreholes are not suitable to incorporate into a large water supply system, because there will be a necessity to have a multitude of boreholes at different locations to feed a large area. Furthermore, the unit production cost of borehole systems is also much more than a surface water scheme. The topography of selected project area is mostly continuous steep small mountains with shallow bedrock, and flat lands are seen in limited areas. Therefore, potential areas for groundwater development are limited and unevenly distributed. Notwithstanding, it is prudent to pursue in this endeavor, as this is the most feasible alternative for remote areas to provide limited supplies. This is because such systems are more economical than to utilize centralized surface water sources with complicated and expensive treatment systems. But most of CWSSP schemes are also not functioning properly due to yield and water quality problems. 6.2.3 Mahaweli River This is the largest river in Greater Kandy area with a total catchment area of 91,292 km2 (3,118 km2 at Polgolla and 1,109 km2 at Nanu Oya mouth), and a daily average flow rate of 5.5 million m3/d, and annual average rate of flow of 2 billion m3/d, which has a host of major tributaries namely Kotmale Oya, Atabage Oya, Nillambe Oya, Pinga Oya, Hulu Ganga, Maha Oya, Hasalaka Oya and Heen Ganga and a few other minor ones within the district. The Mahaweli River is the major source of water supply to prescribed Kandy North area and the existing greater Kandy feeding area as discussed in the previous section. In crosses this area from southwest direction to northeast direction up to the centre of Kandy, and then flows nothewords. The lowest land elevations in the Kandy North project area is along the Mahaweli valley. The flow of Mahaweli river in the project area under consideration is regulated by the operation of Kotmale Dam at upstream end, and Polgolla Dam at downstream end. River flow is monitored daily at Peradeniya Gauging Station by the Irrigation Department, and inflows to Polgolla dam is estimated based
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 66
on downstream release and flow for power generation. NWS&DB also install new computerized gauge station at Meewathura water treatment plant to get daily flow rates at Mahaweli river. According to information obtained from the Irrigation Department for the Mahaweli River flow from October 1989 to September 1999 measured at Peradeniya was determined to be 213.68 m3/d or 2,046,000 m3/d, and for 7 day average median flow was 24.57 m3/s or 2,122,900 m3/d. Storage volume of Polgolla Reservoir is 4.1 MCM at normal operating level (at 440.74 m AMSL, surface area 1.2 km2) and the minimum storage volume is 2.0 MCM at 438.90 m AMSL (surface area 0.75 km2). Average retention time in Pogolla Reservoir is around two days based on the median flow at Peradeniya. However, due to accumulation of silt periodically the actual retention time may become much lower than two days, from time to time. The Normal Operating Level at Polgolla reservoir has been set at 440.74 m AMSL. However, under normal circumstances when there is no rain or a threat of floods, it has now been the established a policy not to open the gates to discharge any excess flow up to 10:00 p.m. of the day, due to safety concerns of the people using the river downstream. As a consequence, at times the water level would rise up to about 441 m AMSL during daytime according to the Polgolla Headwork’s management. With this rise the discharge downstream will increase considerably, which will amply alert the downstream users to be cautions, and if the level continues to rise further, the gates will be opened irrespective of the time of the day. The Low Water Level is set at 438.30 m AMSL, and any further drop in this level will cause the power generation at Ukuwela Power Station to be shutdown. The lowest water level recorded during silt removal was 434.34 m AMSL. Under flood conditions the gates will be kept open to control the reservoir level, as designed. According to the historical data on the maximum discharge in the river, it is evident that there is no possibility for the flood water level to rise above 441 m AMSL even under worst possible flood conditions. Table 6.10 summarizes a historical record of the 39 worst floods of the river in the past 58 years from 1943, and the high flood levels reached on each occasion. The table has been prepared on the decreasing order of the intensity of the floods. Polgolla Dam was commissioned in 1976 and the highest flood recorded after this date was in 1978, with the level reaching 440.2 m AMSL at Polgolla. In August 1985, Kotmale Reservoir was also commissioned, which was located upstream of Polgolla Dam. This has facilitated the control of floodwaters in a more effective manner. Thus, the risk of raising the flood water level above 440.70 m AMSL is extremely remote, with the proper regulation of the sluice gates of Kotmale Reservoir, Polgolla Dam and the downstream Victoria Reservoir, which was commissioned in April, 1985. Mahaweli Authority has also evaluated data in respect of worst flood discharges up to return period of 500 years as shown in the following Table.

The Mahaweli Authority has set the minimum flow of the river at 180,000 m3/d except for extremely dry weather conditions. However, it is recorded that in 1992 a serious drought took place causing the rainfall in January to fall to about 40% of its normal average monthly rainfall level with February and March having no rainfall. The river flows also reflected this reduction of rainfall by dropping down the flow to 166,600 m3/d. The number of days recording the flows below 180,000 m3/d was eight in 1992, two in 1993 and there in 1997. The maximum daily demand of Greater Kandy existing feeding area and proposed Kandy North project area in year 2017 is assessed to be 182,500 m3/d of which the existing systems (KMC, Nilambe Oya, Hulu Ganga, Udu / Yatinuwara etc.) will continue to supply 65,040 m3/d from year 2005 to 2015. Hence, the required abstraction from Mahaweli River is 102,000 m3/d in 2035. (Say 110,000 m3/d), and according to the past flow records of the river this appears to be realistic. Nevertheless, the possibility of arising abnormally high dry periods in future cannot be ruled out, and in such situations restricting the supply will become inevitable. This underscores the need to preserve the existing groundwater sources for possible standby utilization in such a situation. As already mentioned the source of supply for KMC system and a few other systems is the Mahaweli River. The proposed Kandy North Water Supply System is also based on the same source, as there is no other alternative surface water or ground water source, which can provide a bulk volume of 110,000 m3/d with a suitable raw water quality. NWS&DB has already secured the water rights from the Mahaweli Authority for the utilization of 180,000 m3/d from the river, which includes the existing systems utilizing Mahaweli River as the source such as KMC system (33,400 m3/d). Hence there is still a certain surplus remaining for further extraction from the river elsewhere, if the need arises (agreement between NWS&DB and MASL is attached in Annex 6.2). 6.2.4 Water Quality The Mahweli River is the largest river in Sri Lanka and flows around the Kandy City and provides drinking facilities to around 700,000 of people in Kandy district by constructing 8 Nos. of water intakes along the Mahaweli river. Therefore, testing of river water quality is important for sustainable and reliable drinking water supply system of NWS&DB. The water quality parameter of Mahaweli River is testing since 2001. At the moment, as per the test results, raw water quality is not contaminated and physical treatment and chemical (cl2 addition) treatments are sufficient to purely the water up to SLS standards. Water quality data and analyzed reports are attached in Annex 6.1 in treatment plants, aerators, flocculater and sedimentation tanks and slow sand filters are the typical water treatment plant arrangements. Mada Ela is one of the tabutaries of Mahaweli River which flows through the Kandy city area starting from Kandy Lake. According to the test results water of Mada Ela is highly polluted even through this water flows to Mahaweli river. Kandy Municipal Council and NWS&DB have implemented a new sewerage project to prevent discharging of sewerage and other waste to Mada ela. 6.2.5 Treatment facilities As mentioned in early chapters existing Katugastota plant will be phase out to match with the demand of the area. Intake was constructed in Phase I Stage I of Greater Kandy WSP to meet daily demand of 115,000 m3/day. Raw water main, distribution chamber, one unit of flocculation & sedimentation basin, 04 no. of filters, clear water pump house, one clear water reservoir, chemical building & administration building also constructed under this Phase I Stage II. 4 no. of filters and new clear water reservoir & chemical improvements to the treatment process will be constructed in the water treatment plant under Kandy North project proposal.

6.3 Design Aspect and Water Supply Proposal - Kandy North Project Water Supply to Harispattuwa Division Harispattuwa DS division is one of the growing demand centers in Kandy North area covering 84 numbers of GN divisions. Total area of the division is 50.25 km2. The intake and water treatment plant is located in Gohagoda and Katugastota areas respectively and belongs to Harispattuwa D S division. Kandy North Water Supply Project is designed in order to cover the entire Harispattuwa division by expanding water supply facilities to other areas. Kurudugahamada (elevation 675 m MSL), Barigama (600 m MSL), Yahalatenna (625 m MSL) and Uduwawala (510 m MSL) are the reservoirs that will be constructed under Kandy North proposal. These new reservoirs will be fed from Yatiwawala booster pump station and intermediate pump stations. The 800mmdia trunk line from A4 pumps of WTP at Katugastota to cater the Harispattuwa and Poojapitiya divisions was laid up to Yatiwawala intermediate elevated reservoir under Phase I Stage II of the Greater Kandy Project. The pumping main of Pujapitiya was laid up to Rajapihilla under the Phase I Stage II of the same project and this line will be extended to Madawala under phase I Stage III of the Greater Kandy Project. Harispattuwa was one of the highly water shortage area during 1980s and Finida project was implemented to solve this problem. These existing water supply areas were augmented by Phase I Stage I & II of Greater Kandy water supply project. Refer line diagram 1. Water Supply to Pujapitiya D S Division Pujapitiya DS division has 67 GN divisions and total area is 58.60 km2. Pujapitiya is the high water shortage division in Kandy district and 85% of division will be covered by Kandy North Water Supply Project. Transmission main to feed Pujapitiya will be laid along Madewela Pujapitiya road. Pujapitiya 1 and 2, Bokkawala, Godahena and Galinna are the new reservoirs which will be constructed under this project. Water supply will be extended upto Ankumbura existing scheme under KNWSP. Refer line diagram 1I. Water Supply to Akurana Division Akurana DS division has 35 GN divisions and total area is 30.40 km2. Akurana, Kahawatta, Kurugoda were the newly constructed service reservoirs of Phase I Stage I and Thelambugahawatta is Phase I Stage II reservoir under Greater Kandy Water Supply Project. Dippitiya, Rambukeelagama, Vilana Udagama, Balakaduwa and Heepitiya are the new reservoirs under the Kandy North Project and Vilana and Owissa existing reservoirs are also fed from the system. Dunuwila will be catered from Pathadumbara transmission under the Kandy North Proposal. Refer line diagram 1II.

Water Supply to Pathadumbara Division Pathadumbara DS division has 52 GN divisions and total area is 50 km2. Pathadumbara division, considered as an area of priority in Kandy North Project. It is said that most of shallo wells in this division are dried up after constructing Ukuwela tunnel in 1975. New service reservoirs, Jambugahapitiya, Udathalavinna, Pitiyegedara, Wattegama, Doragamuwa will be constructed under this project and Akurana - Dunuwila new reservoir also will be covered from Pathadumbara transmission. Provision is already available to cater the Pathadumbara from two water treatment plants at Polgolla and Katugastota. According to the new master plan, existing reservoirs such as Polgolla, Bangalawatta, Pihilladeniya, Napana, Uyanwatta will be covered from Polgolla plant and new reservoirs will be catered from Kandy North Water Supply project through Akurana (North - A3 Pumps) transmission of Katugastota plant. New reservoirs adjoining to existing reservoirs Bangalawatta, Pihilladeniya, Napana, Polgolla, Uyanwatta will be constructed to improve the service level under Kandy North Water Supply Project. 600 mm diameter transmission is already laid to match the Kandy North Water Supply Project demand in future from Pingaoya junction to Doragamuwa junction. In future Bodigala existing reservoir in Kundasale division will be fed from Polgolla water treatment plant and pumping main construction will be implemented under Kandy North Water Supply Project. Refer line diagram 1V. Water Supply to Kandy Four Gravets Division Kandy Four Gravets DS division has 62 GN divisions and total area is 58.95 km2. Both Kandy Municipal area and Gangawata Korale Pradeshiya Sabha areas are in Kandy Four Gravets DS division. Kandy Municipal area is already 100% covered with drinking water supply from Katugastota, Meewathura and KMC plants. New reservoirs Heeressagala Low, Middle, Bahirawakanda, Uplands and Dangolla were to be constructed early which were deleted from phase I stage II of Greater Kandy Water Supply project. Hanthana call link, Thalwatta and Radagaspanawatta new reservoirs will be constructed under Kandy North Water Supply Project. The drinking water problem will be completely solved in Kandy Four gravets after the implementation of Kandy North Water Supply Project. NWS&DB and KMC are sharing the water in order to cater the Kandy Four Gravet division. NWS&DB supply water to KMC Asgiriya and Upland reservoirs from Katugastota Plant. In Phase I Stage II, NWS&DB will supply 17,000m3/day to KMC and extract 4,000m3/day to Ampitiya area from R3 reservoir and 2,000m3/day to Thennekumbura and 1000m3/day to Hanthana areas from R2 reservoirs. Currenty KMC plant operates its maximum capacity and in future, Asgiriya supply from Katugastota plant will be increased to match the increasing demand of KMC and other NWS&DB water supply areas (Ampitiya, Hantana, Heerassagala & Thannekumbura) which are feeding from KMC plant. Refer line diagram V. Water Supply to Thumpane Division Thumpane DS division has 67 GN divisions. The part of the Thumpane division such as Kopiwatta, Girihagama, Arambekade, Niyangoda areas etc. are covered under Phase I Stage II of Greater Kandy Water Supply Project.

CHAPTER 7
7.0 ECONOMIC AND FINANCIAL ASPECTS
7.1 Financial Aspects
Cost Estimation
The based year for the financial analysis is year 2012.
The following works are proposed to be accomplished under Kandy North Water Supply Project.
i. Construction of 2nd Filtration unit for Water Treatment Plant
ii. Construction of Clear Water Reservoir for Water Treatment Plant (3rd Unit)
iii. Improvements of water treatment plant (Supply and installation chemical pumps and Clear
water pumps)
iv. Construction of Service Reservoirs - 28 Nos.
v. Construction of Pumping Stations - 17 Nos.
vi. Installation of Transmission Pipelines - 86 km
vii. Installation of Distribution Pipelines - 411 km
viii. Construction of Quarters for NWS&DB staff
ix. NRW reduction and rehabilitation programme
7.2 Basis for the Costing and Assumptions
In general, most of the rates are based on the NWS&DB rate book 2012. 27% overhead and profit were added to the basic rates. Greater Kandy Water Supply Project Phase I Stage II MAGA Engineering rates (2009 January - ICB contract) with inflations were used when the rates are not available in the NWSDB rate book. I. Transmission and Distribution Pipes
There are about 86 km of transmission lines and 411 km of distribution lines to be laid under Kandy North Water Supply Project.
Cost estimation was done for laying of transmission and distribution pipelines according to specification 2 (i.e. backfilling with quarry dust and imported earth). Estimates are mainly based on 2012 NWS&DB rate book. The supplying and laying cost for DI pipes, PVC pipes and fittings are separately estimated. For this estimate it was assumed;
• 40 thrust blocks per km.
• 01 sluice valve per km with fittings and chamber.
• 02 air valves per km with fittings and chamber.
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 74
• 06 culverts per km (03 with washout and 03 without washout).
Laying cost covers the excavation with earth work support and dewatering if necessary, installation of pipes with fittings, sand bedding, backfilling with surrounding material (quarry dust / sand) and imported soil with compaction (95% - 100%) etc. In addition provisions have been made for temporary reinstatement of pipe laying trenches. The detailed estimates are given in Annex 7.1.2.2, Annex 7.1.2.3, Annex 7.1.3.2, Annex 7.1.3.3, Annex 7.1.4.2, Annex 7.1.4.3, Annex 7.1.5.2, Annex 7.1.5.3, Annex 7.1.6.2 & Annex 7.1.6.3. II. Road Reinstatement Estimate
The permanent reinstatement cost was estimated based on actual road categories such as RDA, PRDA and PS. For RDA roads, 5% supervision charge was considered and reinstatement will be done by the contractor.
For PRDA and PS roads, rates are based on PRDA and PS submitted rates for 2010. For 2010 rates 10% inflation was considered for 2012. The detailed estimates are given in Annex 7.1.2.8, Annex 7.1.3.8, Annex 7.1.4.8, Annex 7.1.5.8, and Annex 7.1.6.8.
III. Service Reservoirs
Proposed service reservoirs under Kandy North Water Supply Project will be constructed in 5 DS divisions in Greater Kandy area. 28 Nos. of new service reservoirs with a total capacity of 7,650 m3 are to be built to facilitate the distribution system. Some new reservoirs will be constructed adjoining to the existing NWS&DB reservoirs to improve the service level of existing consumers. Other reservoirs will be erected in high elevated areas. Therefore, reservoir cost includes the cost of access road if necessary, tentative bulk excavation, fencing and landscaping etc. Most of the unit rates are based on NWS&DB 2012 rate book. The detailed estimates are given in Annex 7.1.2.1, Annex 7.1.3.1, Annex 7.1.4.1, Annex 7.1.5.1 & Annex 7.1.6.1. IV. Pump Stations – Civil, Mechanical & Electrical Estimates There are 17 Nos. of pump stations to be built in the transmission system in Kandy North Water Supply Project and 50 Nos. of pumps are to be installed. The estimate for civil cost is based on Greater Kandy Water Supply Project Phase I Stage II Sierra company rates (2009 January) for ICB contract (Contract No. : RSC-C/Gr.Kandy/ Civil/2008/03A) in year 2010 with 10% inflation. For the M & E cost, rates are based on MAGA company rates which were submitted for ICB contract in year 2010 with 10% inflation. The detailed estimates are given in Annex 7.1.2.6, Annex 7.1.3.6, Annex 7.1.4.6, Annex 7.1.5.6 & Annex 7.1.6.6.

Nsg 75
V. Water Treatment Plant Mainly a filtration unit and a clear water reservoir are to be constructed under Kandy North Water Supply Project at Katugastota WTP. Supply and installation of 5 sets of pumps and 2000 KVA electrical substation will be installed clear water pumping stations under Kandy North Water Supply Project. Further, a clear water pump house of 100 m2 area is to be added to satisfy the additional space requirement of Kandy North Water Supply Project pumps. The details of estimates are given in Annex 7.1.1.3. VI. NRW Reduction and Rehabilitation This investment is timely requirement for sustainable water supply and the NWS&DB is planning to decrease the NRW to 25% in year 2025 in all schemes. Rehabilitation need and NRW reduction programmes are under preparation. VII. Land Acquisition
Actual market values of lands obtained by interviewing land owners and villagers are used for estimating land acquisition cost. Total estimated cost for Kandy North water supply project is Rs. 9,746 Million (Nine thousand seven hundred and fourty six Million Rupees). Estiamte is given in Table 7.1. VIII. Estimation of Priority Areas As per the PAC comments, this report is revised based on priority areas (DS division wise) but people are highly demanding drinking water equally in all five DS divisions (Pathdumbara, Akurana, Harispattuwa, Pujapitiya, and Kandy four gravets). Therefore it is difficult to prepare priority order but prepared the estimate for DS division wise. Refer table 7.1.1

7.2.2 Calculation FIRR
Objectives and Scope of Analysis
The objective of this financial analysis is to calculate the Financial Internal Rate of Return (FIRR) of the project. Calculation of the FIRR is based on the revenue & expenditure of Kandy North Water Supply Project with proposed inflation.
The financial analysis should ensure that the project is financially viable, meaning that it generates revenues sufficient to cover capital and operating costs. Revenues include those derived from water tariffs and other related charges that are directly attributable to the project. This rate of return is expressed as the Financial Internal Rate of Return (FIRR).
The FIRR is defined as the discount rate, or rate of return, which equalizes the present value of incremental project costs to the present value of incremental revenues. Therefore, the project is considered to be financially viable if the FIRR is equal to, or greater than, the actual cost of project funding.
In order to identify those factors posing the greatest risk to the financial viability of the project, an analysis of the sensitivity of the FIRR to adverse changes in selected key variables is also undertaken.
Major Assumptions
The major assumptions employed in the financial analysis are as follows:
Scope
The financial analysis presented in this section considers the cost of rehabilitating the existing scheme and the incremental revenues and costs directly associated with the total Greater Kandy Water Supply Project Phase I & II.
Forecast Period
The FIRR is calculated over the 45 year period, from 2012 to 2057, which incorporates the preparation, construction and operating periods of the project.
Price Basis
All revenues and costs are expressed in LKR on an incremental basis and the base year is taken as 2010. Increment of O & M cost is considered as 2% per annum, tariff is as 25% for every 5 years, connection fees is as 25% for every 10 years, O/H for personal (Head office/RSC/Manager O&M) is as 10% for every 5 years.
Incremental Costs
The FIRR is calculated on the basis of the incremental capital costs, incremental operating and maintenance costs and incremental revenues of the project.
Non-Revenue Water (NRW)
30% of the water produced is considered non revenue up to 2025 and thereafter 25% is considered as non revenue.
Incremental Revenues
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 81
The FIRR is calculated on the basis of the projected incremental revenues attributable to the project. This is calculated as the projected incremental volume of water sold multiplied by the proposed water tariff plus new connection charges.
Water Production and Sales
Total water production is calculated according to the water demand and improvements of water treatment plant.
No. of connections are calculated assuming monthly water consumption as 14m3 for a family and that is 0.6 m3/day for a connection. The determination of the demand and the production quantities are dealt with in more detail in chapter 5 of this report.
Sale of water to the KMC is priced at Rs 16.00 per CUM (current national bulk rate) while that to the others is priced at Rs 24.00 per CuM for Domestic consumers and at Rs. 37.00 per CuM for Non domestic consumers.
Capital Costs Capital costs are described in the Kandy North Water Supply Project estimate. The expected construction is estimated to be completed on 2018. Specific replacement costs have been provided over the evaluation period for the rehabilitation and or replacement of mechanical and electrical equipment.
NWSDB receives the funds required to implement the proposals from the treasury and 15 % of the total funds to be repayable from NWS&DB within 20 years after a grace period of 06 years, at 10 % interest rate as per the subsidiary loan agreement (balance 75% of loan to be paid by treasury from taxes).
Operating Costs
Incremental operating costs are based on the expected incremental costs of additional water production and sales. The cost of operation and maintenance for the project is computed by calculating year 2008, 2009 & 2010 O&M costs for the Greater Kandy Plant and its two distribution zones Akurana and Harispattuwa.
The O&M cost of GKWSP plant and distribution zone can be categorized as follows. 1) Personal cost for head works which includes personal salaries, overtime etc. 2) Electric / Energy cost. 3) Chemical cost (including chlorine, alum, lime and bleaching powder etc.). 4) Repair and maintenance cost which includes the cost of leak repair, new connection and
extension of distribution system etc. 5) Establishment cost - This include the telephone bills, vehicle cost maintaining of office
equipments, security and rental etc. 6) Overhead (head office, RSC and Manager (O&M) Kandy North office). This was assumed as
Rs. 50/- per connection per month.
When calculating the O&M cost, personal expenses, energy cost, chemical cost, repairs and maintenance cost of transmission and distribution and establishment costs are taken and considering the total water production of those years (Year 2010, 2009 & 2008), above costs are calculated as a cost in Rs. per m3.
Annual extension and new connection costs are taken and considering the no. of new connections given in those years, cost per connection is calculated.
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 82
Details of O&M costs are given in Table 7.2.
Revenue
Revenue is calculated from the income from water selling to KMC and other consumers and the income from new connections. The actual selling quantities and selling prices for the year 2010 was considered and increment of tariff is considered as 25% for every 05 years and the increment of connection fees is considered as 25% for every 10 years. The economical analysis (referred to NWSDB) for the Kandy North project investment and returns is carried out based on the above. The IRR is found to be 10.2%, indicating that the investment is economically viable. The details are given in Table 7.2.1. Total O & M. cost and revenue details are attached in Annex 7.2.

CHAPTER 8
8.0 Conclusion and Recommendation 8.1 Conclusion A complete master plan review of water supply up to the planning horizon of 2035 for the Greater Kandy area is carried out in this exercise and the study reveals that in years 2013 and 2017 additional major augmentation is required to meet the demand. The augmentation required in year 2013 is identified as the priority project as the Kandy North Water Supply Project and the project proposals are prepared for seeking funds. However, water demand in the project area continues to increase gradually and the need for the next Phase of the project is clear in 2015. This may be reviewed again in the future and appropriate decisions could be taken depending on the performance of the already completed project components. The following conclusions are arrived based on the facts discussed in the preceding chapters by implementing the Kandy North Water Supply Project.
1. The majority of the existing borehole water supply schemes have their own limitations in production and quality of water, and there is an urgent need for rehabilitation of augmentation from Kandy North Water Supply Project. The need has been proven through the high demand and beneficiary interest as shown in the socio-economic surveys and the consultation made with the relevant authorities including NWSDB, Divisional Secretaries, health authorities, private sector agencies etc.
2. Scarcity of reliable and safe water sources in there, especially during the dry spells of the year, has
made the problem acute.
3. Capacity building of the O&M authorities by providing physical facilities, actively involving the O&M staff in project functions, making them aware of the importance of consumer relations etc. need to be done. Expansion of resources and their functions at the NRW unit Kandy is an absolute need.
4. It is recommended to undertake public hearing as an ongoing process of the proposed project for
its overall success. 5. It will be possible to improve the service level of nearly 450,000 of existing consumers and to
provide service facilities to new Beneficiary population of nearly 250,000 with an improved coverage of 85 %.
6. Rapid expansion of population associated with rural industries and other economic activities;
suburbs of the Kandy North area, has become highly inhabited and will continue to be more inhabited in the future.
7. A larger portion of the people (62 %) in the Kandy North area do not access to safe drinking
water and suffer for want of water. Further the situation is aggravated by the recent development works carried out in the area and the hamlet expansion.
8. Large number of applicants (more than 42,000) for supply connection in the waiting list is a solid
commitment to the fact that they are determined to get water as they undergo untold hardships for want of water.
^tÇwç aÉÜà{ jtàxÜ fâÑÑÄç cÜÉ}xvà
Nsg 84
9. People are willing to get the service connection since the average monthly water bill value for a rural family is less than Rs 355.00 for nearly 80 % of the consumers in the Kandy region. Also about 80 % of the household in the project area pay more than SLRs 640.00 and about 60 % pay more than RS 440.00 as the monthly electricity bills. This is a positive indicator that majority of the households will get the supply connections.
10. The O & M cost is Rs 21.00 per m3 of water and the domestic billing rate is Rs 24.00 per m3 for
other existing consumers. Therefore continuous and formulated tariff revision is required for smooth functioning of Kandy North Project and to meet the Mahinda Chinthana goals.
11. Once the project is implemented it will cover an area of 340sq. km. This is a tremendous
achievement in terms of infrastructure development with pipe borne water, which will create a greater development potential impact in the rural economy paving way for more and more investment in the area.
12. Water service available means that good sanitation practices which leads to healthy life of the
inhabitants in the area leading to improved health conditions which means a saving medical expenses amounting to about Rs 500.00 Mn a year.
8.2 Recommendation

According to the data depicted in the table 8.3, the Project is operationally as well as financially viable without 75% Capital Cost Recovering.
The construction activities of Kandy North Water Supply Project should be implemented comply with CEA regulations, NBRO regulation and RDA traffic regulations with close supervision of NWS&DB and other utilization organizations. The incremental cost (Refer Table 7.1.2) of this Kandy North water supply project is very law compared with other water supply projects due to most of facilities such as intake, water treatment plant at Katugastota and transmission main are already constructed under phase I stage I and II of Greater Kandy water supply project to meet the final demand. (year 2035). After implementation, Kandy North water supply project will be benifited total of 450,000 people in Kandy city and suburbs 6 DS divisions. The project is technically feasible, economically viable, and socially acceptable with no adverse environmental degradation. Since a major portion of the spade work for the Kandy North Water supply project is already accomplished by already constructed GKWSP intake facility to match with the year 2030 demand and lands are already acquired for improvement of water treatment plant. It is strongly recommended to consider the Kandy North Water Supply Project proposals favorably and make necessary arrangements to seek suitable funding agency to implement the Kandy North Water Supply Project in order to provide the anticipated facilities. According to the activity programme constructions will be completed during year 2016 if funding agencies are finalized end of 2012.
