Future Projects

Water Sector Development Project III

The Kalu Ganga Water Supply System in Colombo District and the neighbouring Kalutara District has been improved in phases with assistance from Japan International Cooperation Agency. However, the increase in water demand caused by rapid population growth is outpacing the development of water supply facilities. it is estimated that the gap between water demand and water supply will increase to atleast 100,000m3/day in the area served by the Kalu Ganga Water Supply system by 2020. Many of the existing transmission mains and distribution networks were installed 50 to 100 years ago. Partly because of water leakage from these old, deteriorated pipelines, the percentage of non-revenue water (NRW) at around 40% exceeds the national average of 31%.

In order to meet the increasing water demands following tasks are regarded as urgent issues.

1) Augmentation of the capacity of Kalu Ganga Water Supply system

2) Improvement of water supply efficiency by replacement and repair of the old existing transmission

& distribution pipes

Against this background, the Government of Sri Lanka is planning to implement a Water sector Development Project III, for the extension of the existing Kalu Ganga Water Supply system in Colombo and Kalutara Districts where rapid urbanization is in progress and rehabilitation of transmission mains and distribution networks in Dehiwala and Moratuwa, where the ratio of NRW is particularly high in the area, with an ODA loan from Government of Japan.

The service area to be covered by KGWSP Phase II is Homagama, Kesbewa, Moratuwa, Ratmalana & Padukka DS Divisions in Colombo District and Bandaragama, Bulathsinghala, Horana, Ingiriya, Kaluthara, Madurawala, Milleniya & Panadura in Kaluthara District.

The projected population to be served under the Phase II of the project is 854,567 in 2020 and 1,544,232 in 2040 under the Phase III of the project.

The water treatment plant capacity will be 140,000 m3/day for the Phase II & 140,000 m3/day for the Phase III as well.
