EVALUASI KINERJA JARINGAN DISTRIBUSI AIR BERSIH DI KECAMATAN MOJOAGUNG KABUPATEN JOMBANG

The residents of Mojoagung Subdistrict need clean water for their survival and their daily activities from washing clothes, bathing and drinking. Over time, the population growth rate affects the quantity of clean water in the area. From these conditions it is necessary to evaluate in order to optimize the distribution of clean water to serve consumers as a whole. The purpose of this study is to calculate the water demand at the study site and to plan the development of a clean water distribution network system in Mojoagung District. For the pipeline network planning process, a software device, namely Waternet, is used. The average need for clean water in 2021 will reach 4.93 lt/sec and 7.40 lt/sec at peak hours with a total source water capacity of 17 lt/sec. Meanwhile, for the period of development, the average water demand is 10.69 lt/sec and the peak hour requirement is 16.04 lt/sec. The results of the simulation and evaluation for the performance of the distribution network in 2021 get the relative energy results between 16.14 m – 20.10 m. Then in the planning year (2031) the results obtained Relative Energy of 16.14 m - 20.10 m and experienced additional nodes to reach new consumer areas, namely the Mojotrisno and Miagan areas as many as 9 nodes and 9 pipelines with a total length of 1289 m with a diameter of 2.5 inches
