Clean water is essential for human life, yet not all residents have access to this basic necessity. In Sumbermanjing District, many residents still lack proper access to clean water, even though many water sources are available in this district, one of which is Kali Jaruman. To distribute water from Kali Jaruman to Sumbermanjing District, a pipe network is essential. This research proposes seven pipe materials available in factory. Pipe materials proposed are HDPE PN 16, HDPE PN 12.5, HDPE PN 10, PVC PN 12.5, PVC PN 10, Black pipe SCH 40, Galvanized SCH 40. To determine the ranking of pipe material alternatives, the Analytic Hierarchy Process (AHP) method was used, using three criteria: pressure, lifespan, and construction cost. Based on the AHP analysis, Black Pipe SCH 40 ranks highest, while PVC PN 12.5 ranks lowest.
