Manila Water continues to deliver steady round-the-clock water service to its customers, supported by three major water systems: the Angat-La Mesa Water System, the Laguna Lake Water System, and the Antipolo Water System. Long-term investments in these sources have strengthened supply reliability even as the utility faces pressures from the strong El Niño phenomenon, dropping water levels at Angat Dam, and rising demand across its coverage area.
“As we experience the full effects of a strong El Niño and the pressures it places on traditional water sources, our diversified supply systems provide greater resilience and flexibility in meeting the needs of our customers. These strategic investments help ensure that communities across the East Zone continue to have access to safe and dependable water services today and in the years ahead,” said Dittie Galang, the company’s Corporate Communications Group head.
The Angat-La Mesa system remains a key source for Metro Manila. Working with the Metropolitan Waterworks and Sewerage System, Manila Water has backed projects to secure enough water flow into Angat Reservoir, such as the Sumag River Diversion Project and the rehabilitation of the Umiray-Angat Transbasin Project.
Laguna Lake serves as a vital supplementary source under the Laguna Lake Water System. The 100-million-liter-per-day Cardona Water Treatment Plant draws water from the lake’s central section, supplying some 800,000 people in Rizal and nearby localities. The 16.5-billion-peso East Bay Water Supply Project is also in progress along the lake’s eastern shore. Its first phase, a 50-million-liter-per-day facility, already serves parts of eastern Rizal and will eventually cover up to 390,000 residents. The 200-million-liter-per-day second phase, set to open within the year, will benefit roughly two million people in Pasig, Pateros, Taguig, and other parts of Rizal.
The Antipolo Water System meanwhile caters to Rizal’s growing demand through the Wawa-Calawis network, anchored on the recently acquired Upper Wawa Dam with a capacity of 710 million liters daily. The 80-million-liter-per-day Calawis Water Treatment Plant currently serves around 900,000 people in Antipolo City and surrounding areas. The upcoming 220-million-liter-per-day Kaysakat Water Treatment Plant, drawing water from Upper Wawa Dam, will be finished later this year and supply an additional one million residents in Antipolo and neighboring towns.
Combined, these three systems form a robust and varied supply network that allows Manila Water to consistently provide safe, reliable, and sustainable water services to over 7.9 million customers across the East Zone.
