Based on BKBP in 2019 Perumda Tirta Raharja only serves 10% of the area of Bandung Regency, RISPAM was made in Kabupten Bandung which is divided into several regional development one of which is Soreang Subdistrict. Soreang district has an area of 25 km2 with a population in 2018 is 120,848 people. In the service of drinking water Kab. Bandung is served by Perumda Tirta Raharja, based on BKBP in 2019 Perumda Tirta Raharja only serves 10% of the area of Bandung Regency At the beginning of 2021, for the Soreang area the number of served home connections amounted to 7251 SR or as many as 36250 people equivalent to 30% of the population of Soreang, so it is necessary to increase access to drinking water services around the Soreang area.. Soreang region water services are currently sourced from Sadu WTP operating in 2019, and Sukamaju with each in 2021 Non Revenue Water respectively is 22%.and 31% which is still above the tolerance limit of NRW of Permen PU No.20 / PRT / M / 2006 .Distribution network planning is designed for the next 15 years through 3 alternatives, namely grid system, combine system and branch system using PE-PN 10 pipe, then running modeling using EPANET 2.0 software. The best alternative is determined using the SAW assessment method with the prerequisite of meeting the technical criteria of SNI 7509: 2011, obtained the results of the assessment with the highest value, namely the alternative Grid system with the formation of 8 DMA. The result of the calculation of reservoir capacity was obtained by 4232 m3
