PDAM Kupang Regency has experienced losses in recent years. This is due the current distribution system can not meet customer needs and highly operational and maintenance costs. Meanwhile, on the one hand, there are two potential water resource as alternative raw water resource of PDAM Kupang regency, i.e., Tilong Reservoir and Baumata Springs. Therefore, it required a utilization review on its technical and economic side of both potential sources of water. A review was conducted by comparing the existing and the planning condition. The existing conditions and new network planning modeling was analyzed by Waternet Software version 2.1, of total water demand is based estimated population in 2025 with a target service level of 50%. The economic feasibility Analysis of the new network was based on BCR value (bennefit cost ratio) by bennefit components were selling water to the new network and losses of existing condition, while the cost components were initial construction and operating costs and maintenance of new network. Modeling results indicate that alternative networks capable of distributing water to customers without rotation. Economically, new network planning is eligible to be built of design life over than 11 years. Assuming banking interest rate of 15%, new network planning gives BCR 1.1 on 11th year.
