DURIANGKANG WATER PROCESSING, PENGELOLAAN AIR WADUK DURIANGKANG DENGAN PERMEABLE REACTIVE BARRIER SEBAGAI UPAYA MENGURANGI KRISIS AIR BERSIH DI KOTA BATAM

Abstract

Clean water is water that has good quality for use in daily life. According to PT Adya Tirta Batam (2020), Batam City has been experiencing a clean water crisis since 2018 because the amount of clean water in existing reservoirs has decreased. The main reservoir in Batam City is Duriangkang Reservoir. In providing water, 80 percent or 228,900 citizens there depend on this reservoir. The benefit of this paper is to take advantage of the existing regional potential. The method that can be used for water remediation is the Permeable Reactive Barrier (PRB). The application of PRB is to treat acid mine drainage (AMD). The research method that the author uses is a literature review, by looking for research on the problem of water availability, and the condition of reservoirs in Indonesia and then looking for solutions to these problems. Water management efforts use a Permeable Reactive Barrier (PRB), namely by flowing reservoir water into a smaller stream and installing PRB at the end of the stream to remove pollutants carried by reservoir water. PRB contains limestone, carbon, phosphate, aquifer material, ZVI that can remediate water. However, this water cannot be used as consumption water. Therefore, it is also necessary to sterilize water using electricity by utilizing the potential energy from the water itself. After the author's ideas are applied, it is hoped that the w ater in Duriangkang Reservoir can be utilized optimally and can become a clean water solution in Batam City.
