Water security projects top Manila Water’s 2025 Capex program

MANILA, Philippines — Manila Water Company Inc. rolled out a robust capital expenditure program in 2025, focusing on securing new and additional water sources and reinforcing critical infrastructure to ensure 24/7 water service across its East Zone service area amid rising demand, especially during the summer months.

The company said its 2025 capital expenditure program reflected its focus on service reliability and long-term water security across its concession.

A key objective of the investment rollout was to diversify water supply sources and help ease pressure on Angat Dam by developing alternative and complementary raw water facilities for communities in the farthest and most elevated areas of the East Zone.

A significant portion of the 2025 capital outlay was allocated to the development and expansion of raw water sources. Manila Water said investments in water source projects totaled more than P12.4 billion, covering treatment facilities and upstream developments designed to strengthen supply availability, particularly during peak consumption periods.

Among the key initiatives were the continued development of the Wawa water supply system, including the Wawa Kaysakat facilities, Kaliwa-Wawa common facilities, and Phase 1 of the Wawa Pasig treatment plant.

The company said these projects accounted for a substantial share of its water source investments and were positioned to support long-term supply requirements in Metro Manila and nearby areas while providing additional capacity that would reduce dependence on a single source.

Allocations for other source-related facilities such as East Bay and Calawis also supported Manila Water’s strategy of diversifying and reinforcing its water supply portfolio.

The company said these projects would strengthen its ability to manage seasonal demand shifts and maintain reliable water service during the dry months.

Taken together, Manila Water said its 2025 capital expenditure program reflected a focused investment approach centered on water security and infrastructure resilience.

By advancing major source developments, the company said it was strengthening its capacity to respond to increasing demand from the 7.8 million population it now serves, mitigate supply risks amid climate change, and support the long-term needs of communities, especially with expanding urbanization in Rizal province.

Aside from Angat Dam, Manila Water currently gets additional raw water supply from Laguna Lake through its Cardona Water Supply System and East Bay Phase 1 Water Supply System.

The Calawis Water Treatment Plant also provides at least 80 million liters per day. Manila Water also recently began taking over the operations of Upper Wawa Dam, which can supply an additional 710 million liters per day to Rizal province and help lessen dependence on Angat Dam. /mr
