Development of New Water Sources Development of Replacement Source for Irrigation

Development of New Water Sources: Development of New Water Sources:

Angat Dam - the only present source of water supply for the MWSS service area serving a total of 13 million population out of the total service population of 15 million, or only 87% total service coverage. Angat Dam provides a supply volume of 4,000 million liters per day (4,000 mld) out of the present demand of 4,395 mld, or a deficit of 395 mld. By 2015, the projected demand is expected to reach 5,054 mld, thus requiring the development

water to address the increasing demand.

Development of New Water Sources: Development of New Water Sources:

Based on the Supply-Demand Projection, potential new water sources were identified to fill the gap starting 2015 (these are enumerated in the succeeding slides) MWSS will hire consultant:

• to validate water demand study,
• to

undertake the necessary updating, comparative evaluation and prioritization of the various new water sources identified, in order to come up with a new road map;

• to prepare the first priority project biddable by 2012.

Development of Replacement Source Development of Replacement Source for Irrigation: for Irrigation:

Angat Dam is a multi-purpose facility serving domestic water supply, power supply and irrigation water. MWSS’ present water allocation in the Angat Reservoir:

Original Allocation = 22.0 cms Conditional Allocation from Irrigation water rights = 15.0 cms Umiray-Angat Transbasin Tunnel = 9.0 cms TOTAL = 46.0 cms

cms cms = cubic meters per second = cubic meters per second mld mld = million liters per day = million liters per day

Development of Replacement Source Development of Replacement Source for Irrigation: for Irrigation:

In 1988, the National Water Resources Board (NWRB) granted a conditional allocation of 15 cubic meter per second (15cms) to MWSS

the unutilized allocation of the National Irrigation Administration (NIA) irrigation requirement; MWSS is proposing to develop an alternative source to replace/substitute the 15cms of NIA’s allocation from Angat Reservoir.

Development of Replacement Source Development of Replacement Source for Irrigation: for Irrigation:

Technical Working Group (TWG) composed of MWSS, NIA and the Concessionaires (Maynilad and Manila Water) is preparing a Memorandum of Understanding (MOU) for the joint undertaking of the Project (re: 15 CMS Water Source Development Project); The TWG will hire consultant:

• to

evaluate the most viable and best alternative replacement source;

• to prepare the selected source biddable by 2012.
