EVALUASI DAN PENGEMBANGAN SISTEM DISTRIBUSI AIR BERSIH KECAMATAN GEDANGAN KABUPATEN SIDOARJO

The level of clean water service in Gedangan District at the end of 2021 is still 36%. High population growth makes the need for water increase. So the researchers concluded for the need for clean water at the study site and planned the development of a clean water distribution network system in Gedangan District. Projection of the selected population is using the Geometric method. In analyzing the clean water distribution network, the EPANET 2.2 program is used. From the results of the analysis, it is found that the water demand in 2021 at peak hours will reach 186 liters/second, the maximum daily water needs will be 108 liters/second, and the average water needs will be 98 liters/second, while in 2037 the population will reach 147,014 people. at peak hours of 559 liters/second, the maximum daily water requirement is 323 liters/second, and the average water demand is 294 liters/second. The results of the EPANET program analysis show that the 2021 network on the clean water pipeline has a minimum pressure of 11,70 m and a maximum pressure of 22,27 m. As for the development network in 2037, the clean water pipeline has a minimum pressure of 15,37 m and a maximum pressure of 47,18 m
