PERENCANAAN JARINGAN AIR BERSIH DESA NGENEP KACAMATAN KARANGPLOSO

The provision of clean water in Ngenep Village, Karangploso District, Malang Regency has become an essential need in line with population growth, thus requiring a sustainable distribution system planning up to the design year. This study aims to design a clean water distribution network through the analysis of water demand, pipeline network planning, reservoir design, and pump selection, with water sources originating from the Umbulan and Nyolo springs. The methods employed include population projection, water demand calculation, and network simulation using WaterCAD to obtain optimal flow and pressure conditions. The results indicate that the peak hour water demand reaches 42.497 liters per second, with a distribution system utilizing HDPE pipes with a main diameter of 141 mm, a reservoir capacity of 120 m³, and a centrifugal pump with a total head of 80 m. The total estimated project cost is IDR 4,212,636,909.85, with an implementation period of 117 working days. Therefore, the system is expected to meet the community’s water needs effectively, efficiently, and sustainably.
