Kathmandu Valley Water Supply Improvement Project (KVWSIP) 2776 NEP SF

The Kathmandu Valley Water Supply Improvement Project is envisaged to support the ongoing efforts of the Government of Nepal towards improving the water supply services and waste water management system in Kathmandu Valley. The project will invest in bulk water transmission and distribution network improvement systems, and will complement past and ongoing Asian Development Bank (ADB) projects. The resultant synergy is expected to lead to increased efficiencies, greater improvement in service delivery, and higher impact on health outcomes and quality of life in Kathmandu Valley.

The project which is under implementation since September 2012, aims to create an efficient water distribution system by improving upon the water supply services and situation in Kathmandu Valley. Construction of large Service Reservoir Tanks (SRT) at several locations of Valley, Bulk Distribution System (BDS), and Distribution Network Improvement (DNI) are major works that are being carried out under the project with the objective of achieving equitable distribution of Melamchi water to households in Kathmandu Valley. Construction works of the Bulk Distribution and the Service Reservoirs (BDS-SRT) will be completed under five separate packages. Nine large Reservoir Tanks, with a combined water holding capacity of 65000 Cum will be constructed in Arubari, Mahankalchaur, Bansbari, Balaju, Panipokhari, and Kirtipur in Kathmandu, Khumaltar in Lalitpur and Katunje and Tigni in Bhaktapur districts. Construction of 78Kms of Bulk Distribution Pipelineaand 700Kms of distribution pipe laying works will be laid in the valley.

Distribution Network Improvement (DNI) is taken up in three packages to cover eleven service areas. The DNI works are District Metering Areas (DMA) concept which is further subdivided into at least two Sub-DMAs. The Sub-DMA is the smallest service area unit in the distribution network improvement activity, by which performance and functioning of the distribution network may be monitored and evaluated.

Feasibility Study: March, 2010 
Contract agreement with ADB: November, 2011
Budget: 130 Million US Dollar

Objectives

The objectives of the project are as follows: Improve water supply services by constructing, rehabilitating and expanding service reservoirs, BDS and DNI Equitable and continuous distribution of water to the residents of Kathmandu Valley Reduction of NRW by limiting it to less than 15% Improve health outcomes and quality of life for the residents of Kathmandu Valley

Scope of Works

The scopes of services of Kathmandu Valley Water Supply Improvement Project are as follows: A. Rehabilitation and expansion of water supply system Rehabilitate and expand BDS,DNI and service reservoir Provide individual connections to the residents of Kathmandu Valley, especially to the poor and female headed households. Provide 24-hour water supply to at least 10% of service area and Provide bulk and individual meters; reduce NRW and reduce energy losses in electro-mechanical machinery. B. Support for operational and financial improvements and capacity building. Provide capacity building and improve the governance of KVWSMB, KUKL and WSTFC; Implement the KUKL business plan, the NRW assessment and reduction plan, the asset management plan and the gender equality and social inclusion action plan; Update water supply and sewerage GIS database; Strengthen KUKL in community participation and public education for health, hygiene and behaviour change in water conservation, good water management practices including 3 R’s (Reduce, Reuse and Recycle) and rainwater harvesting; Strengthen KUKL in monitoring and evaluation activities; and Strengthen KUKL in managing the Project.

Progress Status:


  • Construction work of 6 large Service Reservoirs in Arubari, Mahankalchaur, Bansbari, Balaju, Panipokhari and Khumaltar has recently started. Other Service Reservoirs in Kirtipur, Katunje and Tigni will be constructed soon.
  • Laying of transmission lines in and around Ring Road have begun: 1348 m BDS pipes have been laid in Balaju-Sorhakhutte and Lainchaur areas.
  • About 246 Kms of distribution pipe laying works have been completed in Koteshwor, Maitidevi, Old Baneshwor, Narephat, Babarmahal, Bagbazar, Sinamangal, Banasthali, Shova Bhagawati, Chamati, Sanepa and surrounding areas.
  • Construction of three tube-wells have come to the end stage and drilling works have started in other three wells under the third phase of tube-well installation program, which targets to install further 20 tube-wells in different locations inside Kathmandu Valley.

Bulk Distribution System and Service Reservoir

Phase 1:

The drinkable water from Sundarijal Treatment Plant to various service reservoirs will be conveyed through Ductile Iron (DI) pipes ranging from 1400mm to 400mm which is about 78Kms. The ninereservoirs at Arubari, Mahankalchaur, Bansbari, Balaju, Panipokhari of Kathmandu district andKhumaltar of Lalitpur, Tigni and Katunje of Bhaktapur districts and Kirtipur with combined capacity of about 65,000cum. In addition, construction of pipe lines in Kirtipur andTigeni and Katunje of Bhaktapur Districts.

Phase II:

Another pipeline having 1600mm diameter will be laid from Sundarijal Treatment Plant to Chabahil Chowk (about 11 km). Similarly, large capacity reservoir at MahankalChaur, Balaju and Khumaltar of aggregate capacity 28000 cum are envisage whereas in Kirtipur reservoir of 6000cum will be constructed .

There are four contract packages in Bulk distribution system and service reservoir in phase I under the loan 2776. The package I includes 10,242cum pipes and total 3 reservoir with the combined capacity of 26,000 cum. The package II includes 24,837m pipes and total of 2 reservoirs having the capacity of 17,000 cum. Package III includes 15, 408m pipes and total of 1 reservoir with the capacity of 7000 cum. The package IV includes pipeline about 15 km and total of 3 reservoirs with the combined capacity of 15000cum. Detailed engineering design regarding this is under process.

Distribution Network Improvement Works for Efficient NRW Management Works

Three contract packages of Distribution Network Improvement Works for Efficient NRW Management Works are on board for the implementation.

During the implementation of the DNI contracts, co-ordination with all concerned authorities, i.e. DOR, KMC, LSMC, NEA and Telecom is required. Permission is required from DOR, KMC and other Agencies for road cutting. In addition, a detail traffic management plan is needed which includes co-ordination with area traffic police if/when there are road closure, an alternate route for diversion plan need to be developed using all advance warning/ information and direction signs. Information required regarding the installation of underground HT line in all major roads by NEA. The information is required regarding installation of underground optical fibre by NTC and NCELL.
