Evaluation and development planning for clean water supply system of Sanih Fountain in Buleleng regency

Abstract

Abstract The rising population and economic activity have induced an increase in the demand for clean water in Buleleng Regency, especially in Sawan, Kubutambahan, and Tejakula District, respectively. The distribution of clean water supply is carried out through house connections and public hydrant by the Water Supply Company of Buleleng Regency with service coverage only reaching 40.09% in 2018. So it is necessary to evaluate and develop plans for the existing clean water supply system to increase service coverage. The evaluation of the water supply system includes an analysis of the availability and demand of clean water based on the population, with a projection for the next 25 years. Analysis of the clean water supply system development plan considers the availability of water resources potential. The evaluation results show that the existing system has not met the water demands in the service area. The development plan carried out to fulfill the demand for clean water is by optimizing the discharge of the Sanih Fountain by 125 liters/second and the construction of the Bungkulan 2 well.
