The TRMP’s main objective is to provide Tumauini farmers with adequate and timely water supply for crop irrigation for a potential service area of 8,200 hectares. The major structures of the TRMP will consist of a high dam, an afterbay dam, and a long siphon. EDCOP was engaged by the National Irrigation Administration Region II to undertake the 3rd party review on the DED of the TRMP.
