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 forthe 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 of

supplementary sources of 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, comparativeevaluation and prioritization of the various new watersources identified, in order to come up with a new road map;

- to prepare the first priority project biddable by 2012.

Development of Replacement SourceDevelopment of Replacement Sourcefor 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

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 out of 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.

Technical Working Group (TWG) composed of MWSS, NIAand the Concessionaires (Maynilad and Manila Water) ispreparing a Memorandum of Understanding (MOU) for thejoint undertaking of the Project (re: 15 CMS Water SourceDevelopment Project);

The TWG will hire consultant:

- to evaluate the most viable and best alternativereplacement source;

- to prepare the selected source biddable by 2012.
