EXECUTIVE SUMMARY A. Introduction 1. The Water Supply Sector Project (WSSP) aims to work with the DWS in establishing a sector performance benchmarking program, which can be used to continually monitor and improve operations and services. The Project will also strengthen the capacity of DWS and participating Nam Papas (PNPs) in corporate governance, O&M, and service delivery. The access to safe water will be improved by construction of new and rehabilitation of existing piped water supply facilities. The project is consistent with the Government’s urban water supply and sanitation sector policy and investment plan and supports the country’s targets for piped water supply for urban population.
