However, in terms of quantity and quality, these water sources have not been able to meet the needs of the population. Rendu Butowe village has the potential of the Terenapu spring which has not been utilized optimally and has only been used by some residents. The purpose of this study is to determine the potential of the Terenapu spring in terms of quantity and quality of water, to determine the population's clean water needs, and to evaluate the potential of the springs for the needs of the population. The survey method used in the research includes measurement of discharge, analysis of water quality, and interviews of residents' water needs. The results obtained are: the discharge of the Terenapu spring is 1,098,357 liters/day.
