JAKARTA - The Ministry of Public Works and Public Housing (PUPR) continues to increase the number of water reservoirs in various regions in Indonesia to increase Indonesia's water storage ratio, from the current 50 m3 /capita/year to reach 120 m3 /capita/year by 2030. In North Sulawesi, the Ministry of PUPR is building two dams, Kuwil Kawangkoan Dam in North Minahasa Regency and Lolak Dam in Bolaang Mongondow Regency, which can accommodate a total of 39.47 million m3 of water.
