Project Objectives/Outcomes:

In Timor-Leste, the presence of poor water quality and widespread faecal bacterial contamination in water sources and the environment poses a significant threat to the health of both children and adults. This contamination often leads to frequent and prolonged episodes of diarrheal diseases, and in some cases, even fatalities. Currently, the wastewater generated in Dili is disposed of directly into the surface aquifer or is channelled into the ocean through the city’s drainage canals without proper disinfection. These practices have resulted in the contamination of both private and public drinking water wells with faecal matter. The primary goal of the WSD Project is to mitigate faecal contamination in the environment and enhance the quality of drinking water, thereby reducing the burden of diarrheal diseases in Dili. The project involves building a brand-new sewerage system from scratch that will benefit around 300,000 people. By doing this, we aim to reduce this contamination and improve the quality of drinking water in Dili, ultimately preventing people from getting sick.
