  • 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.

  • Preliminary Project Information Memorandum
    PRELIMINARY PROJECT INFORMATION MEMORANDUM Project Objective The project concerns structuring and transacting turbines 4 & 5 of the Angat HEPP facility potentially on a PPP basis. The primary objective of Metropolitan Waterworks & Sewerage System (MWSS) is to select a private partner under PPP framework for Rehabilitation, Operation and Maintenance of the units. Project Overview The Angat dam is a multipurpose reservoir with benefits of irrigation, water supply flood control and hydro power. The reservoir supplies about 90 percent of raw water requirements for Metro Manila through the facilities of the Metropolitan Waterworks and Sewerage System (MWSS). It irrigates about 28,000 hectares of farmlands in the provinces of Bulacan and Pampanga under the service area of Angat Maasim River Irrigation System (AMRIS) of the National Irrigation Administration (NIA). During the rainy season, the dam serves as a flood control facility where the reservoir serves as a buffer for the increased water inflow in the watershed catch basin. The Plant is located at San Lorenzo, Norzagaray, Bulacan to the west of the Sierra Madre mountains. Angat Reservoir Angat Powerhouse The integrated Powerhouse complex of the project consists of 2 Power station namely the main and auxiliary. The main power station is installed with 4 Nos. 50 MW hydro electric generation capacity and the auxiliary power station is installed with 3 Nos.6 MW, 1 No. 10 MW and 1 No. 18 MW hydro electric generation capacity. Water that passes through the main turbines exits through a tailrace tunnel 1,800 meter in length and joins the Angat River downstream of Ipo dam.

She is a prominent personality in international environmental law and has received numerous awards and citations for her work. ; The Administrator’s Story on Water Security... ater Security has a soul. It is neither a concept nor a W slogan. It is a call to solid action. Just as it is infrastructure, so too is it policy. But more, much more than all that, it is passion to keep balance an intergenerational resource basic to man. MWSS is central to Water Security in Mega Manila. It desperately tries to keep that balance, that delicate life- equilibrium that can only be achieved with heart. Agencies must not only understand but also embrace the basic truth that such imbalance fundamentally “widens the gap even more between the rich and the poor, the developed and the underdeveloped.” Core to Water Security is environment; the reality of climate change; the impact of MWSS’ implementation or non- implementation of infrastructure; in-depth review and updating of policies and simulations used for decades; technology and methods; the synergy of agencies, both private and public.
