PDAM Jayapura utilizes raw water from surface water or upstream river. This study aims to plan the development of drinking water supply system of Jayapura City in order to be able to meet water service criteria that is quantity, quality, continuity, and affordability. The results showed that the quantity of raw water can be fulfilled by adding from Lake Sentani (scenario I) or existing source from the Jayapura sub watershed that is Kujabu watershed (scenario II). The need for drinking water for up to 20 years is 1.04 m3/sec with a possible service coverage rate of 92%. The selection of Jayapura City SPAM development scenario is based on the feasibility of technical criteria, investment cost, operational and maintenance cost, depreciation cost, and economical drinking tariff based on full cost recovery (FCR). The scenario of water supply system development in Jayapura City, scenario I and II, meets the technical criteria and provides economical rates. However, the selected scenario is scenario II. This scenario is a combination of existing system optimization and addition of production capacity through existing raw water source that is Kujabu watershed. Scenario II provides investment costs, operational and maintenance costs, depreciation fees, low tariffs, and the most economical base rate. The water supply system development provide results, investment costs of Rp. 384.855.764.004,00, operational and maintenance cost of Rp. Rp. 1,827.00/m3, depreciation cost of Rp. 22.962.559.215,00/year, the basic rate (FCR tariff) is Rp. 2.558,00/m3, low tariff of Rp. 1.534,00/m3, and full tarif of 4.324,00/m3. Water supply system services can be done optimally and meet the water service criteria that is quantity, quality, continuity, and affordability.
