This document summarizes a study on the impact of service reservoir staging height on the installation cost of a water supply scheme in Kamayakoundanpatty, India. The study used various methods to optimize the pumping main, service reservoir, and distribution system costs for staging heights ranging from 10-20 meters. Topographic surveys, population projections, and demand estimates were conducted for the area. Pumping main costs were analyzed using software to determine the optimal pipe size. Distribution systems were optimized in software considering different reservoir heights. The staging height that provided the lowest total installation cost was found to be 12 meters for this project.
