MWSS Priorities MWSS Priorities For The Next Six (6) Years For The Next Six (6) Years 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 of supplementary sources of water to address the increasing demand.
Supply – Supply – Demand Projection Demand Projection Supply Demand Deficit Year Supply Source (mld) (mld) (mld) 2009 4,000 Angat Dam = 4000mld 2010 4,100 4,395 295 + Laguna Lake = 100mld 2011 4,250 4,532 282 + Laguna Lake = 150mld + Laguna Lake = 150mld 2012 4,600 4,605 5 + Sumag River = 200mld 2015 5,054 454 4,600 2020 5,680 1,080 4,600 NOTE: Laguna Lake and NOTE: Laguna Lake and Sumag Sumag River will be implemented by the MWSS’ Concessionaires River will be implemented by the MWSS’ Concessionaires
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 or 4,000 mld 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 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. cms cms = cubic meters per second = cubic meters per second
Alternative Sources Alternative Sources To Replace The 15 CMS Conditional Allocation To Replace The 15 CMS Conditional Allocation Project Potential Project Description Supply Cost Volume (Estimate) 1) Apalit-Pampanga River Construction of a diversion/intake structures US$ 110 M to utilize the irrigation return flows and the 20 CMS normal flow available from the Pampanga (PhP 5 B) River Location: Apalit, Pampanga 2) Pampanga River Diversion Construction of a diversion/intake structures US$ 110 M 20 CMS to utilize the normal flow available from the (PhP 5 B) Bagabag River Location: Calumpit, Bulacan CMS = cubic meters per second , US$1.00 = PhP45.00 CMS = cubic meters per second , US$1.00 = PhP45.00

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. - CMS = cubic meters per second CMS = cubic meters per second
