The Upper Wawa pumping station features a 65-meter deep shaft, a one-kilometer tunnel, and a conveyance pipeline capable of delivering 518 million liters of raw water per day. The facility will deliver water to the Manila Water treatment plant for distribution across Metro Manila.
The system is designed to trap floating waste—particularly plastic—before it flows into the ocean. It is expected to divert around 97,000 kilograms of waste per year, including over 13,000 kilograms of plastic.
Prime Infrastructure Capital Inc. of billionaire Enrique Razon Jr. has partnered with global construction consultancy Mace to establish a project management office for its two large-scale pumped storage hydroelectric power projects—the 600-megawatt (MW) Wawa and 1,400-MW Pakil facilities.
Both plants are now supplying clean energy to the power grid, with Prime Solar holding a 50-megawatt, 20-year power supply agreement with Meralco and delivering the surplus to the grid.
It aims to integrate afforestation, reforestation, and revegetation with sustainable livelihoods, biodiversity conservation, and climate change adaptation. The project also seeks to generate nature-based credits, aligning environmental goals with economic opportunities.
The infrastructure firm of billionaire Enrique Razon Jr. said the initiative aims to address long-standing water supply challenges, improving access to clean water essential for health, hygiene, and sanitation.
The preemptive release of water from Wawa Dam in Rizal at the height of Super Typhoon Carina last week helped mitigate flooding in the low-lying areas of the province and easter Metro Manila, the company that manages the joint venture project said over the weekend.
Prime Infra said its 64-megawatt solar power plant in Maragondon, Cavite will boost the output of another facility in Tanauan, Batangas to collectively supply 128 MW of clean energy.
