The WSD Project seeks to reduce pathogens in piped and stored water and groundwater through a catalytic infrastructure investment that will introduce the country’s first central wastewater system, make related improvements to the drainage network, and build a plant to produce disinfectant chemical that will be used to treat the city water supply across the capital city of Dili and four nearby municipalities. The project will also support key policy and institutional reforms to support long-term sustainability of the infrastructure and social and behavior change efforts to improve household water management and hygiene practices.
