The National Irrigation Administration (NIA) (Filipino: Pambansang Pangasiwaan ng Patubig) is a Philippine government-owned and controlled corporation primarily responsible for irrigation development and management in the country. NIA was created under Republic Act (RA) 3601 on June 22, 1963. Its charter was amended by Presidential Decree (PD) 552 on September 11, 1974, and PD 1702 on July 17, 1980. Both increased the capitalization and broadened the authority of the Agency. NIA's forerunner was the Irrigation Division of the defunct Bureau of Public Works. NIA was placed under the Office of the President (OP) upon its creation. It was attached to the Department of Public Works, Transportation, and Communication under PD No.1, dated September 23, 1972. The issuance also integrated all irrigation activities under the Agency. The Administrative Code of 1987, dated July 25, 1987, attached NIA to both the Department of Public Works and Highways (DPWH), and Department of Agriculture (DA). But NIA remained attached to DPWH. It was transferred to OP pursuant to Executive Order No. 22, dated September 14, 1992. Then, it was attached to DA under Administrative Order No. 17, dated October 14, 1992. More information...
