Sanitation is specifically discussed in the 6 SDGs goals, including by 2030, achieving universal, adequate, safe and affordable access to drinking water for all and implementing integrated water resource management at all levels. This research aims to evaluate the quality of water before and after processing by PDAM (Water Supply Company) Wonosari Unit and examine the effectiveness of PDAM Wonosari Unit water treatment so that it can be used optimally as a source of raw water for community drinking water. The Paguyaman River is one of the large rivers in the Gorontalo Province region which is the geographical boundary between two districts, namely Gorontalo Regency and Boalemo Regency. The Paguyaman River is that it is used as a raw water source for PDAM Wonosari Unit drinking water The location of this research was in Bongo 2 Village, Wonosari District. There were 2 sampling locations, namely 1 location in the Paguyaman River water before the PDAM intake and the 2nd location in the PDAM reservoir after the processing process. The data required in this research were primary data including physical parameters including temperature, Total Dissolve Solid (TDS), turbidity, and color; Chemical parameters included iron, pH, and manganese. Bacteriological parameters covered total coliform bacteria and escherichia coli. Data collection in the field was carried out 3 times. Secondary data included data on PDAM water users, the population. Chemical parameter samples were analyzed at LPPT UGM. Physical and microbiological samples were tested at the Gorontalo District Health Laboratory. Analysis of river water quality data compared to its suitability based on Government Regulation Number 22 of 2021 attachment VI and for PDAM water compared with PERMENKES No. 2 of 2023. The results of the analysis show that Paguyaman River water meets the requirements as raw drinking water. Evaluation of PDAM water quality, for microbiological parameters, does not meet the requirements because the Wonosari Unit PDAM water treatment system sometimes experiences major problems with the water pump sometimes shutting down so that the disinfection treatment process does not work optimally. © 2025 Author(s).
