| Abstract | Optimal design period, investment cost and o/m cost model equation, and imputed water supply benefit are presented to evaluate and to improve rural water supply in West Java. Those critical evaluations are needed, since the Indonesian Government through Directorate of Cipta Karya under Department of Public Works has decided to render a new inception phase,
according to the new selection and design/planning criteria, and since the money is one of the three major constraints. LAURIA (1972) discovered that for design periods which are less or greater than optimal design
period, the present value cost increases. Considering 12%, 15% and 18% rate of interest, the optimal design periods in West Java are 13 years,
10 years, and 9 years respectively.
To get investment cost model which can improve the construction of rural water supply, the samples were selected utilizing existing successful constructions in West Java. The investment cost for water system without any treatment plant and distributed by gravity, covering transmission lengths up to 4,000 m and 4,000-9,000 mare around US$30,000 and US$50,000 for one 1ps respectively.
O/M cost models were established in a similar manner as in the development of investment cost model. Around 6-7 c/m3 for one 1ps average capacity is needed to maintain and operate rural water supply in West Java. The imputed water supply benefit method is the tool to evaluate timing of implementation of water supply projects or to make decisions regarding the timing of new projects in the absence of budget constraints by comparing the value of water that would be assigned by constructing now with the true value of water inferred from the imputed water supply benefit. In west Java, by using this tool, the implicitly assigned value cannot exceed 13.00 c/m3 for implementation to be currently acceptable. |
