History[edit]

Built in 1926, 50 kilometers upstream from the Bustos Dam as a fixed type river weir without gates, the AARD, Angat Afterbay Regulator Dam (commonly known as Bustos Dam) is the longest rubber dam in Asia at 79 meters and the second largest in the world.[2] It has coordinates of 14°57'25"N 120°57'15"E serving nearby cities: Real, Quezon, Rodriguez (Montalban), Rizal, Antipolo City, Rizal.

In 1967, steel sector gates were installed on top of the regulator dam for the purpose of generating irrigation water, power supply and domestic water supply.

Rehabilitation[edit]

With its construction, the Bustos Dam's height was increased by 2.5 meters and later renamed Angat Afterbay Regulator Dam, increasing the service area of the Angat-Maasim Rivers Irrigation System (AMRIS), which operates the AARD from 25,000 hectares in 1927 to 31,485 hectares in 20 towns in Bulacan and Pampanga benefitting 20,562 farmers.

The series of typhoons from 1968 to the early part of 1980 was damaging to the dam whose Bay 1 sector gate finally gave way in September 1990 after typhoon "Iriang" carried away the structure 250 meters downstream from its original post. The agency has undertaken temporary rehab works in the dam using their own budget and through funding assistance from the World Bank.
