ABOUT NIA

The National Irrigation Administration (NIA) is a government-owned and controlled corporation (GOCC) primarily responsible for irrigation development in the Philippines. It was created under Republic Act (RA) 3601 on 22 June 1963. Its charter was later amended by Presidential Decree (PD) 552 on 11 September 1974 and PD 1702 on 17 July 1980, both increasing its capitalization and broadening its authority. Its forerunner was the Irrigation Division of the defunct Bureau of Public Works. PD No.1, dated 23 September 1972, integrated all irrigation activities under NIA.
