We intend to increase the number of improved sanitation systems and services through an output-based approach among low income households in Greater Colombo. Improved access to sanitation services should result in improved health and environmental conditions for the population living in targeted areas, by ensuring that domestic wastewater is effectively managed and appropriately disposed of. This will be accomplished through new connections to networked centralized or decentralized sewerage, and improved on-site sanitation in partnership with municipalities as well. The effort will be taken by the National Water Supply and Drainage Board (NWSDB), with the vision to be the most prestigious utility supplier in Sri Lanka.

Our objective extends to pilot OBA (Output Based Aid) as an efficient mechanism for delivery of improved sanitation services to low income households.
