|Description||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 cubic meter (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 proposed financing modality is a Project loan.|
|Project Rationale and Linkage to Country/Regional Strategy||
Provision of water supply and sanitation in Metro Manila (Manila) is the responsibility of MWSS, a government-owned corporation. In 1997, it awarded two concession contracts to private firms for water distribution. MWSS retained responsibility for bulk water supply. The privatization of the distribution services brought about significant improvements in the delivery of water supply services. The serviced population has doubled since 1997, of which more than 90% have 24 hours access. The nonrevenue water level (NRW) of over 60% in 2002 currently ranges from 10 to 40%. MWSS's capacity to fulfill its responsibility of ensuring and securing the availability of raw water to the concessionaries needs to be strengthened by: (i) rehabilitation of the raw water transmission system; and (ii) adopting a comprehensive water safety, risk- and asset management system.
Rehabilitation works. Manila's main water supply source is the Angat reservoir, which provides about 97% of Manila's water supply. Water from the reservoir is conveyed through a system of tunnels and aqueducts to water treatment plants in Manila. The treated water is then distributed to households, businesses, and industries in Manila, and parts of Cavite and Rizal.
The demand on the Angat water source is about 4.48 million cubic meter per day (m3/day), and is slightly decreasing from 2010 to 2015, as a result from the very successful NRW reduction programs of the concessionaires. However, following 2015, the demand will increase rapidly due to expected water supply area expansion and population growth. The demand is expected to increase by 38% in 2025 to 6.16 million m3/day.
|Impact||The impact of the project is aligned with MWSS's strategy to provide sustained and secured water supply to Metro Manila from the Angat reservoir, through the Umiray Angat Ipo transmission system.|
|Description of Outcome||Tunnel from Ipo dam to Bigte settling basins operational|
|Progress Toward Outcome||Physical progress of tunnel construction is on schedule. The Tunnel Boring Machine is being constructed on site and works are expected to commence in February 2018. Consolidation works of the hill side are completed as well as retaining walls for the construction of an access road.|
