The community-based drinking water and sanitation provision program is a government initiative that aims to increase infrastructure development to meet the community's drinking water and sanitation needs. In 2018, the implementation of a community-based drinking water supply scheme called Pamsimas resulted in the construction of clean water facilities. So that the Pamsimas program can be managed effectively and sustainably, a Drinking Water Users Association (HIPPAM) was formed. The above program has been implemented in Prayungan Village for five years and an evaluation needs to be carried out to determine the program's achievements in terms of cost, effectiveness, adequacy and achievement of objectives. In addition, it is important to assess community perceptions and reactions to management-oriented drinking water supply schemes. Therefore, the main objective of this research is to assess the effectiveness of the drinking water scheme implemented in Prayungan Village. This research uses a qualitative descriptive approach using purposive sampling techniques to select participants and conducting interviews as the main method of data collection. This study focuses on evaluating
effectiveness, efficiency, adequacy, consistency, responsiveness, and accuracy. The findings show that the assessment of community- managed drinking water supply projects is in line with the expected results. However, there are several challenges that are still being faced, including problems related to the efficiency of clean water distribution, salinity in water quality, and delays in water delivery to residents. When considering efficiency, it is important to address potential barriers that may arise in the adequacy of water pipes. In addition, water distribution may not be accessible to all residents due to the presence of existing wells. In addition, there may be a delay in response in handling complaints. However, it is important to consider the various benefits that individuals gain from this initiative, especially meeting their clean water needs. Several recommendations can be proposed to overcome the above problems. This includes conducting outreach efforts to the community, implementing penalties for late surrender, building additional water storage facilities, using distillation techniques to reduce salt water problems, and increasing the efficiency of rapid response services
