Kolbano Village is a semi-urban village located in the 3T area with water quality that is not suitable for consumption. As a sample, it was found that the water from the three springs in the study area, namely the Oemakine, Oenais and Nunbesi springs, contained total dissolved solids, coliforms and iron content that exceeded quality standards. Not only that, due to climatological and geographical conditions and the lack of adequate springs, the quantity of water accessible in Kolbano Village is limited and not prevalent. Therefore, planning will be carried out for a clean water supply system fit for consumption for the entirty of Kolbano Village For planning the Clean Water Supply System (SPAB), one route was chosen which will be applied directly to the planning with a dead-end system using HDPE pipes flowed by gravity. Meanwhile, for Water Treatment Plants (WTP), there are three alternatives which were selected using the Analytical Hierarchy Process (AHP) method. The total population that will be served by this system is 2,490 people. The planning sub-system planning is carried out in one stage directly to serve 100% of the total production capacity of each water source. The selected unit configuration consists of single media slow sand filtration which will filter suspended particles, turbidity, iron and manganese, and total coliform, then the processed water will go through an ion exchange unit to reduce the TDS.
