Evaluation of community-based water supply system in Krembung, Sidoarjo

Based on the National Medium Term Development Plan (RPJMN), access to drinking water is expected to reach 100%. However, PDAM Delta Tirta Sidoarjo has only been able to serve the drinking water by 37%. In concern to this fact, the Sidoarjo's Government launched Penyediaan Air Minum Berbasis Masyarakat (PAMSIMAS) in Krembung Sub-district. Therefore, to determine the condition and implementation of the PAMSIMAS program, an evaluation through technical and non-technical aspects is needed to provide solutions and recommendations on improving PAMSIMAS' performance. The data collection was conducted by doing surveys, water quality analysis in the laboratory, measuring water pressure using a pressure gauge manometer, and giving out questionnaires. The distribution system is continuous for 24 hours and serves 1.458 house connections. At its farthest point, the water pressure ranges from 4,80 - 7,50 mH2O. The water quality analysis showed that turbidity, color, iron, manganese, and total coliform did not meet the quality standard. About 47% of the respondents are interested in becoming customers. Factors that influenced the interest in becoming customers are water quality and limitations of the network. The solution and recommendations that can be applied are built a water treatment plant and developing new piping systems.
