After 3 years of rehabilitation, the Angat Afterbay Regulator Dam or mostly known as Bustos Dam, a run of the river type of dam, located in Tibagan, Bustos, Bulacan is at 98.66% completed where the major scheme of work is the replacement of rubber gates in seven (7) pier measuring 79 meters each laid above a concrete ogee dam measuring at 76.9 meter each pier. The remaining work so far is the installation of sprinkler in the rubber gates.

The removal of the old and brittle rubber gates took a bit too long due to a continuous flow of water from the upstream coming from the Angat Dam in Norzagaray, Bulacan which is allocating irrigation water amounting to 32.5 cubic meter per second to store 9 million cubic meter in its reservoir, aside from prioritization to complete first the Dam’s downstream apron which is also part of the rehabs major component.

The rehabilitation project wash being pushed forward to keep safe the dam itself and the whole community lying in the downstream portion which will be adversely affected once it burst out and disbursed millions of gallons of waters per second. The collapse of the dam may cause for multiple casualties and loss of millions worth of properties

The overall objective of the project is to rehabilitate the AARD and its appurtenant facilities to prevent from further damage; to improve irrigation water delivery and cropping intensity of AMRIS Service Area in support to the agricultural development program of the government; and to serve as flood control during rainy season to prevent flash floods at the downstream of Angat River.

The project construction aimed to serve 23,708 farmer beneficiaries and irrigate 31,485 hectares of farmlands covered by 16 municipalities of Bulacan and 4 municipalities of Pampanga whose main crop is palay.

The budget for the rehabilitation was sourced out to the Manila Waterworks and Sewerage System as stipulated in a Memorandum of Agreement by and between the MWSS and the NIA in the amount of 1Billion Pesos.
