Abstract

Percentage of drinking water accessability is indicator for measuring the fulfillment of sustainable drinking water needs. PDAM Way Rilau is provider of drinking water need in East Teluk Betung which serve 335 house connection, equivalent to 1.340 people (only 2,48% of the population). For increasing this percentage to ensure sustainable drinking water access, Consumer-level evaluation is needed to assess aspects that need improvement, especially in technical terms regarding the drinking water distribution network. The results of this evaluation can be used as a basis for developing access to drinking water services. This research aims to assess the technical performance of the PDAM Way Rilau distribution network and formulate alternative solutions for technical parameters such as flow rate, flow speed, and pressure that do not meet technical criteria. Based on a survey of 57% of respondents, it was found that the water distribution is not functioning well. An evaluation conducted using the Epanet 2.2 numerical model showed that at peak hours, several points have negative flow rates, pressures below 10 m, and speeds below 0.3 m/s. The chosen alternative to address these issues is to change the pipe dimensions and install valves at several junctions
