Conclusions: Water availability was good mostly got water from Municipal Corporation supplied piped connection with problems of leakages owed to old infrastructures and poor maintenance which needs a planned solution Water scarcity in summers with reluctancy in saving and reusing water still prevails. Water storage and household drinking water treatment practices were good with problem of withdrawing water by dipping glass in the containers and hand touching the water surface. Extensive IEC activities are needed to increase people’s awareness about water saving reuse and water withdrawing practices.
