Perencanaan Sistem Jaringan Distribusi Air Minum di Kawasan Industri Kuala Tanjung dan Sekitarnya, Kabupaten Batu Bara

Abstract

Providing clean water is an effort to meet people's needs for a healthy, clean and productive life. However, in reality access to clean water is still limited, especially in the Batu Bara Regency area. This study aims to obtain clean water needs in 6 villages in Batu Bara Regency, namely, Kuala Tanjung Village, Pematang Kuing Village, Mandarsah Village, Lalang Village, Tanjung Harapan Village, and Tanjung Kubah Village, for the next 10 years and obtain a water distribution network plan the best clean by PU Ministerial Regulation No. 27 of 2016 from a review of water pressure and velocity with the help of the EPANET 2.0 program. The water source will be used from the Tanjung River with a watershed area of 1.542 km2 and a 90% reliable discharge of 17,97 m3 /second. The population projection results for 2033 using the exponential method are 32.539 people, the total need for clean water at peak hours is 176,4 liters/second. Using a 20" HDPE pipe. From the pipe hydraulics simulation using EPANET 2.0 results, it was obtained that the pressure was 35,3 m, and the flow velocity in the pipe was 1,21 m/s. The highest headloss on the pipe was 5.97 m/km.
