Human life is inseparable from the need for water. Water is needed to meet various needs, especially clean water or drinking water which is needed to ensure human survival. One of the efforts made by the community in Teiraplu District to meet their needs for clean water is to use the Yegorker River and collect rainwater. Until now, residents are still fulfilling the need for clean water in the Teirapu District by collecting rainwater so that the need for clean water in the Teirapu District cannot be fulfilled in terms of quality, quantity and continuity. This study aims to study the feasibility of the Yegorker river water source and analyze the water demand in the Teiraplu District, Gunung Bintang Regency. The population in this study were all people in Teiraplu District, Gunung Bintang Regency with an area of 1,469 km2 divided into 10 villages with a population of 1,486 people. The analysis used to answer the problem is to project the population using the Geometric Analysis Method, while the analysis of water quality by taking samples in the study area and analyzed at the Jayapura Health Laboratory Center. The results of the study show that the total available discharge in the Yegorker river is in the lowest condition of 60 liters/second. Based on the analysis of the calculation results, it is known that the total amount of discharge is able to serve 100% of the population's needs of 7.33 liters/second for the Teiraplu District service area, Gunung Bintang district.
