Angat Water Transmission Improvement Project

Closed

The Project will secure raw water supply to the 13 million inhabitants of Metropolitan Waterworks and Sewerage System (MWSS) service area, through the rehabilitation of the Angat transmission line. It is estimated that currently each day about 800,000 m3 or 20% of the total potential capacity of raw water is lost , due to leakage of the aqueducts . The main components of the Angat transmission line are as old as 50 years, in poor condition, and not in compliance with structural and seismic requirements, risking the partial interruption of Metro Manila's water supply. The impact of the Project is sustained and secured water supply from the Angat reservoir. The outcome is the sustained operation of the aqueducts, to be achieved by (i) retrofitting, rehabilitating and/or re-construction of the aqueducts; and (ii) operationalization of an integrated water safety, risk- and asset management plan.The Project will finance the (i) rehabilitation and/or reconstruction of the aqueducts, and (ii) technical assistance to (a) assess structural and seismic integrity of the transmission system; (b) prepare water safety, risk- and asset management plans, covering the optimization of the system; (c) prepare designs of structural and non-structural measures to support the implementation of these plans; and (d) prepare subsequent investments. These investments may include rehabilitation and retrofitting of intakes, stilling basins and the remaining aqueducts.
