Angat Water Transmission Improvement Project Metro Manila, the Philippines
Angat Water Transmission Improvement Project Metro Manila, The Philippines i Summary Metro Manila also called the National Capital Region (NCR) is situated in the south eastern part of the Philippines. Serving as the main economic culture and educational center, the region is a densely populated metropolitan area. The Angat Water Transmission Improvement Project (AWTIP) was designed to ensure secured and sufficient raw water supply to meet the current and future demands of the rapidly growing population of Metro Manila. The project focuses on the construction of a new 6.3 km tunnel (no. 4), intake structures at the Ipo dam and connecting structures of the transition basins, new aqueduct (no. 6)., rehabilitating and retrofitting of existing tunnels and aqueducts. The project is expected to restore the water transmission capacity of the Angat transmission system which currently operates about the 30% below its design capacity. Given the rapidly growing population of a highly populated Metro Manila, the project would ensure that a maximum capacity of 4.65 million m3/d of raw water is transmitted from the Angat dam at maximum efficiency. In addition, the execution of the project is expected to build the technical capacity of the staffs of the Metropolitan Waterworks and Sewerage System (MWSS), who are the primary administrators of the project. The project features social and economic aspects that are targeted towards improving the livelihood and health conditions of source community’s programs and indigenous people. The project also has in place environmental safeguards that aim at reducing and mitigating direct and indirect impacts on the biotic and abiotic parts of the environment.

Angat Water Transmission Improvement Project (Additional Financing) (RRP PHI 46362-004)
Angat Water Transmission Improvement Project (Additional Financing) (RRP PHI 46362-004) FINANCIAL MANAGEMENT ASSESSMENT A. Introduction 1. A Financial Management Assessment (FMA) has been prepared in accordance with Asian Development Bank’s (ADB’s) Guidelines for the Financial Management and Analysis of Projects (2005) and Financial Due Diligence A Methodology Note (2009) and the Financial Management Technical Guidance Note (2015). 2. The FMA considered the capacity of Executing Agency, the Metropolitan Waterworks and Sewerage System (MWSS), focusing on fund flows, staffing, accounting policies and procedures, internal controls, financial reporting and monitoring and internal and external audits. 3. MWSS was created by virtue of Republic Act 6234 passed on 29 June 19711. Its mandate is to ensure an uninterrupted and adequate supply and distribution of potable water for domestic and other purposes at just and equitable rates. In the same year when Republic Act 8041 (known as “The Water Crisis Act”) was passed in 1997, MWSS entered into a 25-year Concession Agreement with two private operators. This effectively transferred the operational responsibilities to Manila Water Company and Maynilad Water Services. Under Article 2 of the Concession Agreement,2 “MWSS grants to the Concessionaires, as contractor, to perform certain functions and as agent, the sole right to manage, operate, repair, decommission and refurbish the Facilities in the Service Area, including the right to bill and collect for water and sewerage services supplied in the service area (the “Concession).” MWSS-Corporate Office (CO) retained the management of Umiray-Angat Trans-basin Project3, monitoring, reporting and administering loans and other related functions while the MWSS Regulatory Office (RO) implements the provision of the Concession Agreement.

Philippines: Typhoon Koppu Situation Report No. 1 (as of 18 October 2015) This report is produced by OCHA Philippines in collaboration with humanitarian partners. It was issued by OCHA Philippines. It covers the period from 17 to 18 October 2015. The next report will be issued on or around 19 October. Highlights Typhoon Koppu makes landfall in Casiguran town in Aurora province on 18 October, weakening from a Category 3 to Category 1 strength. This slow-moving typhoon will bring heavy to intense rainfall along its path as it moves north over the Luzon island and heads out to sea around 21 October. There are no confirmed deaths and injuries so far. Some 14,300 people have evacuated to 108 evacuation centres. Communication is down in parts of the affected area and the full extent of damage is unclear. The Government has not called for international humanitarian assistance so far but asked the Philippines Humanitarian Country Team to be on standby to augment national relief efforts if needed. 14,300 108 200-300 People evacuated Evacuation centres mm accumulated rainfall in a day Source: NDRRMC, PAGASA Situation Overview Typhoon Koppu (known locally as Lando) made landfall over the town of Casiguran in Aurora province in Central Luzon (Region III) as a Category 3 typhoon on 18 October, 1 a.m. local time. It remained almost stationary for more than four hours, according to the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA). The typhoon was near Pantabangan municipality, Nueva Ecija province in Central Luzon at 10 a.m. It slowed down significantly from 12 kph to 3 kph upon landfall and weakened to a Category 1 strength, packing maximum sustained winds of 150 kph near the center and gusts of up to 185 kph.

A CASE of ANGAT DAM,PHILIPPINES Patricia Ann JARANILLA-SANCHEZ1, Yoshi SHIBUO1 and Toshio KOIKE1 University of Tokyo1
OPTIMIZATION OF DAM OPERATION FOR MAXIMIZING WATER USE AND FLOOD PREVENTION: A CASE OF ANGAT DAM,PHILIPPINES Patricia Ann JARANILLA-SANCHEZ1, Yoshi SHIBUO1 and Toshio KOIKE1 University of Tokyo1 ABSTRACT: Angat dam is the main domestic water resource for metropolitan Manila. Optimal dam operation is very important in avoiding possible conflicts between different stakeholders who utilize water from the dam. There are 3 main functions of the dam: 1.) for irrigation purposes in the surrounding provinces of Angat (Bulacan and Pampanga province); 2.) for hydropower generation and 3.) for domestic water use in Metro Manila. Conflicts between stakeholders for these three functions are rampant. This study aims to minimize some of the water-related non-political issues that usually arise between stakeholders. There are two main priorities of the dam optimization for Angat: 1.) To maximize water use and 2.) to prevent flood. This study explores different cases of 3 typhoons from 2011 (Pedring, Quiel and Ramon) by utilizing 50% priority on preventing downstream flooding and 50% priority on water use. In addition, the effects of changing the weights of the objective function in the dam optimization for each priority is also determined to identify how the error is minimized in the optimization system. This system can be a useful tool in utilizing ensemble forecasts to minimize the effects of floods in the downstream side while maximizing the storage capacity of upstream reservoirs during dam operation. KEYWORDS: dam optimization, flood prevention, water use 1. INTRODUCTION and use water effectively. Appropriate dam operation can reduce flood peaks Local residents of Metro Manila rely on Angat dam and water storage can be done more efficiently.

New Water Sources Projects of the Metropolitan Waterworks and Sewerage System (MWSS)
New Water Sources Projects of the Metropolitan Waterworks and Sewerage System (MWSS) Mr. Ramon B. Alikpala Chairman, Board Of Trustees Metropolitan Waterworks and Sewerage System (MWSS) MWSS Priorities For The Next Six (6) Years Development of New Water Sources Development of Replacement Source for Irrigation 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.
