Abstract

Clean water must be met in terms of quality, quantity and continuity. Clean water quality that has not been met according to quality standards will harm people’s health. Rural communities often face the problem of unmet quality of clean water. The Ngudi Tirto Rural Drinking Water Supply System serves the clean water needs of the Kebonromo hamlet community. Water sampling is needed to determine its quality level. Sampling was carried out at several points to determine the distribution of quality levels. The quality levels taken are pH, Fe, KMnO4 and DO. The distribution of water quality levels was analysed using ArcGIS software with the IDW method. Clean water quality standards are based on Minister of Health Regulation no. 32 of 2017. Based on the results of water quality levels, it shows that the pH value is between 6.9 and 7.8. Fe quality levels obtained values between 0.1 mg/l and 0.3 mg/l. The quality level of KMnO4 obtained values between 6.162 mg/l and 15.01 mg/l. And the DO quality level obtained a value between 1.15 mg/l and 2.7 mg/l. The distribution of clean water quality levels along the distribution network is as follows, for pH levels of 100% which meet quality standards, Fe levels of 100% which meet quality standards, KMnO4 levels of 87.5% which meet quality standards and DO levels which do not meet quality standards.
