“…The perpetual increase in water demand due to population growth requires a properly modelled WDN applying the computing technologies, including hydraulic modelling (Ramesh et al, 2012;Sonaje & Joshi, 2015). Significant reviews are done in public domain models like EPANET, Branch and Loop; and commercial models like Aquis, WaterGEMS and WaterCAD.…”

High Non-Revenue Water (NRW) and unreliable water supply services are major challenges in operations of the water networks in most of the fast-growing cities in developing countries. The present study aims at investigating the extent that the existing distribution network contributes to the prevailing high percentage of the NRW; and explore optimization scenarios focusing on water loss reduction and system improvement in the unplanned network. The measured system flow and pressure were used for water balance assessment, calibration and modelling to simulate different scenarios in order to improve system performance. The results showed 52% of the junctions in the system had high pressure above recommended which contributed to 87% of real loss and 83% of pipes had low velocities below the set thresholds. These indicate that uneven distribution of pressures and velocities are driven by improper topology of both pipe sizing and supply directions in the unplanned network. About 50% of NRW was detected in the study area while the entire network had 37%, thus small areas assessment and pressure management are required. The pressure reduction by optimizing installation of pressure reducing valves and change network topology reduced NRW by 46%. In addition, regular nodal hydraulic analysis and flow modifications performed well when integrated with stochastic town growth for system capacity torelance. The study provides ways for sustainably improving the poorly performing water networks in fast-growing towns. It also recommends methods of integrating pressure management, network topology change and resilient to future demand for attaining a better system performance.

Municipal Waterworks Tirta Musi manages and supplies clean water to Palembang city. The distribution network system of Municipal Waterworks Tirta Musi is expected to distribute water sufficiently to all customers in the 18 districts this Municipal Waterworks serves. However, it was found that in Alang-alang Lebar service unit water was not delivered sufficiently. Moreover, Alang-alang Lebar service unit plans to improve the service so that the system will serve increasing customers until the next 20 years. This study aims to analyze the water distribution system to find the cause of insufficient water in Alang-Alang Lebar; predicting the number of customers in the next 20 years, and propose some improvements in the distribution system. A computer program EPANET was used to conduct the simulations on pipe networks. Data required for hydraulic analysis using EPANET was obtained from Municipal Waterworks Tirta Musi. The result shows that head pressure was the main problem in Alang-Alang Lebar. Adding discharge of pump reservoir, enlarging pipe diameters in some parts will improve the distribution performance. The proposed design of the distribution system will be able to deliver water for the next 20 years with an increasing number of the customer.
