Evaluasi Jaringan Perpipaan Distribusi Air Bersih di Kecamatan Stabat Kabupaten Langkat Menggunakan Aplikasi Epanet 2.2

Abstract

Drinking water is water that has gone through a processing process or without a processing process that meets health requirements and can be drunk directly. The availability of drinking water is one of the determinants of improving people's welfare, which is expected to increase the degree of public health with the availability of drinking water. The need for the provision and service of drinking water is increasing from time to time, which is sometimes not matched by the ability of the service. PDAM services cannot be separated from the distribution system which is a pipeline network, so it is necessary to evaluate the distribution system of PDAM Tirta Wampu Unit Stabat. Things that need to be evaluated are pressure, speed, and headloss. To evaluate the clean water distribution system in Stabat District, the method used is the Epanet 2.2 program. Based on the calculation results, the average customer usage in PDAM Tirta Wampu Unit Stabat is 132,7 liters/person/day with a water loss percentage of 32,35%, which is 42,9 liters/person/day. Prior to evaluation, out of 26 junctions, 6 were found to have pressure values below 10 m, so they did not meet the design criteria. So repairs were made by adding pipe diameter and adding a new pump. After repairs were made, the highest headloss value was obtained in the distribution pipeline network at the Stabat Unit PDAM which was 2,98 m/km, this figure was still in accordance with Minister of Public Works Regulation No.27 of 2016, due to the maximum required headloss of 10 m/km
