Evaluation of Clean Water Distribution Pipeline Network in Sei Rampah Subdistrict Using Epanet 2.2

Abstract

The population growth and increasing demand for clean water in Sei Rampah District require the optimal performance of the Regency Capital Drinking Water Supply System (SPAM IKK). However, the clean water distribution network still faces technical challenges. This study aims to evaluate the existing performance of the SPAM IKK Sei Rampah pipeline network based on pressure, flow velocity, and headloss parameters in accordance with the Ministry of Public Works Regulation No. 27 of 2016. The research employs a quantitative approach with a descriptive-evaluative method through the collection of primary data (field observations and operator interviews) and secondary data (customer database, pump specifications, reservoir capacity, and network maps). Data analysis was conducted using EPANET 2.2 software to simulate the hydraulic conditions of the existing network. The results show that the pressure at all nodes meets the required standards (27.98–66.43 m), but 80 pipes have flow velocities below the standard, and 4 pipes exhibit headloss values exceeding 10 m/km. The study concludes that although pressure conditions meet the standards, distribution efficiency is still affected by velocity and headloss issues. The findings imply that this evaluation can serve as a basis for improving the water distribution system and as a reference for future network development.
