Abstract

Reservoir operation and maintenance costs consist of the water service fee from the beneficial water users, and the subsidy from the government. Sustainable operation and maintenance should keep the government subsidy at the minimum level while at the same time considering the willingness to pay from the water users. These two parameters of subsidy and water service fee form an interdependent feedback loop in determining operation and maintenance costs, that belong to the system dynamics phenomenon. This paper calculates the level of government subsidy and the water services fee in order to reach optimal water resources management using a system dynamics approach, in the Jatigede multipurpose reservoir in West Java – Indonesia. Jatigede Reservoir with a volume of 877 million m3 irrigates almost 90 thousand hectares of rice field, providing a public water supply of 3.5 m3/s, and a targeted energy generation of 110 MW. The methodology of using the system dynamics approach is starting with the identification of the interrelated parameters into a causal loop diagram, conversion into stock and flow diagram, and programming using Powersim. It is concluded that the system dynamics approach can reveal the optimal solution, a combination of minimum government subsidy and water services fee within the range of willingness to pay, that minimize the additional maintenance costs in the long term
