Tabanan Regency is one of the regencies in Bali, where the topographical conditions of the existing villages are mostly in remote areas, so they often experience difficulties with clean water distribution problems. For the current condition, the provision of clean water in Tabanan Regency is provided by PDAM (Local Water Company) through the use of springs, ground water and river water, in addition to several areas the water supply is carried out through Pamsimas (Community-Based Drinking Water and Sanitation Provision). Currently Pamsimas Tabanan Regency is divided into 9 service coverage areas for people in rural areas. In general, the condition of drinking water services presents the main problem, namely that not all areas are accessed by adequate water services. This problem is mainly caused by various obstacles such as limited water resources, limited infrastructure and topographical conditions.
