Abstract

Water loss is a severe problem in the drinking water supply system as it disrupts the continuity of the drinking water supply. The largest proportion of water losses is usually found in distribution systems. This study was located in the Beber water supply system, PDAM Tirta Jati Cirebon Regency. The study aimed to evaluate the hydraulic condition and give improvement recommendations for the Beber piping network system distribution. This research performed the International Wafer Association (IWA) water balance concept through water production and water usage data. Furthermore, the hydraulic condition is evaluated using water usage, ground-level elevation, wafer usage pattern, and the existing distribution network's technical data. The evaluation was conducted by simulation using EPANET 2.0 from the Environmental Protection Agency (EPA), which then compared to the design criteria listed in Permen PUPR No. 27 2016. The results show a 44.38% percentage of water loss due to a pipe leak. Simulation results showed a segment of pipe having velocity less than 0.3 m/s (43.31%), and all nodes had pressure below 12.4 MPa. The simulation results also showed some nodes had pressure greater than 100 mKa and exceeded the HOPE SDR 17 pipe's maximum capacity. This condition causes many pipe leaks that occur in the system, so it is recommended to install a Pressure Reducing Valve (PRV) and change of pipe diameter. The study also suggests establishing a District Meter Area (DMA) to detect pipe leak points. Keywords: water loss, distribution network, pipe leakage, DMA, EPANET 2.0.
