Abstract

The water supply system is one of the important hydraulic infrastructures in providing water to consumers. In Nepal, most of the water supply systems are managed by the water supply users’ committee (WSUC). In the present study, it is aimed to evaluate its institutional performance as the system reaches close to the end of design periods. Three water supply systems located in the three different wards are considered in the study. To gather relevant information as per methodology, water quality tests and field observations were carried out to collate primary data and various published field and research reports and related publications were reviewed for secondary data. Furthermore, the technical performance of the water supply system was analyzed based on water supply coverage, per capita consumption, water production for population, water quality test, and physical structure index. The analysis of the results indicates that 69.43% of the area is covered by piped water supply with per capita supply of 50.44 lpcd. The production of water was found as 0.13 m3/day/person. The quality of water at the source is found within National Drinking Water Quality Standards (NDWQS) limit and physical structure efficiency is worked out as 51%.
