The availability and functionality of an improved water supply system among the population are basic human rights and imperative to prevent numerous viral/infectious diseases. The provision of safe drinking water, improved sanitation, and hygiene plays a central role in individual and communal health, but unfortunately, the situation is strikingly poor among nations, especially in developing countries like Pakistan. To understand the existing situation and the impacts of community participation on the sustainability of the water supply system, this study was conducted in the district of Lahore, Pakistan. The prime objective was to find out the participation of the community in planning, execution, operation and maintenance, evaluation process, and the management approaches and techniques with a view of seeing how best community participation level contributed to the sustainability of the water supply program. For this purpose, a simple random sampling procedure was applied to draw the sample from the population. A semi-structured questionnaire was used as a tool for data collection and validated through pilot testing. Results showed that participatory approaches in water supply program planning, execution, operation, maintenance, and evaluation led to community satisfaction and program sustainability.
