Reason Required
During 2008 heavy floods due to Tropical Depression 16 destroyed the suspension bridge located on the Benque River. The bridge used to support a 6 inch PVC pipe to supply water to the Benque community from a spring located on the other side of the river.</p> <p>Presently, Benque community is fed by two ground water wells. The dynamic levels of these wells keep falling. Therefore, the pumps need to be lowered almost every dry season. Rebuilding the existing suspension bridge will allow us to connect back the spring with our system providing extra capacity for the water supply system.
