Colombo Wastewater

Activity Objectives: 

The Swedish International Development Cooperation Agency (Sida), is financing the Ratmalana/Moratuwa and Ja-Ela/Ekala Wastewater Disposal Project in Sri Lanka through a concessional loan agreement with the Sri Lankan government. The implementing agency is the National Water Supply and Drainage Board (NWS&DB). The project is comprised of a gravity and pressurized sewerage network (90km), pumping stations (7 no.), a tertiary wastewater treatment plant (extended aeration and sludge treatment) and a marine outfall. The scope of the project does not include individual household connections, but provides pipe work to the property boundary (interceptor manhole). GPOBA has been approached by Sida and NWS&DB to provide subsidy funds for the connection of individual households to the sewer network that they are funding in the Ratmalana/Moratuwa area.

Development Impact: 

This project aims to bring access to new sewer services to approximately 76,375 people.

GPOBA's role: 

GPOBA will design and fund an output-based aid (OBA) scheme that will provide a subsidy to the NWS&DB for each new working sewer connection to a household in the Ratmalana/Moratuwa area.
