Analisis Kapasitas Tampungan dan Keandalan Embung Wukirsari 1

Abstract

The research on the analysis of the storage capacity and reliability of the Wukirsari 1 Small Dam is motivated by the needs of the community in meeting the needs of raw water. This study aims to determine the amount of reservoir capacity that can be built, as well as the level of reliability of the reservoir after it is used. The reservoir capacity is obtained from a capacity analysis based on water availability, based on water demand, and based on topography. The availability of water in this study was calculated by the F.J Mock method. The reliability of the reservoir is carried out by simulating the reservoir water balance and the reliability level of the reservoir in meeting the community's water needs. The reservoir capacity of the reservoir is 32.407,25 m3 with a live reservoir of 28.506,62 m3 and a dead reservoir of 3.900,63 m3. The projected population for 15 years is 68.384 people with a total raw water requirement of 953.956,8 m3. The reliability level is divided into 3 conditions, the first with a population of 68.384 people, the reliability level is 31,50% and the lowest is 24,07%. Second, with a population of 20.000 people, the reliability level was 100% in February and decreased the following month. Third, with a population of 19.000 people, the level of reliability is 100% every month and can meet existing outflows.
