Optimization of Hydraulic Pressures in Kabacan Water District Pipe Network using h-Newton-Raphson Technique

Abstract

The purpose of this study is to optimize the hydraulic pressures of a real-world water distribution network to protect the system with sustained adequate water supply. This novel approach is different from other published works in the sense that this study is intended to improve the water system of the Kabacan Water District (KWD) in Cotabato, Philippines. Yet, there are no previous scholarly efforts done with the KWD water system; thus, this study. The method used here is a modification of the methods used by references [4] and [14]. This optimization approach includes determination of control valve placement in the network to control the hydraulic pressures within the system. The proposed numerical model, with the EPANET Toolkit interface, resulted in a simpler and more accurate algorithm, which converges easily in all the 48 network models used in this study where the convergence is achieved from 9 to 74 iterations. This is an efficient and easy-to-use optimization solver for analyzing looped pipe networks even in large scale networks.
