Decision scope
Questions answered
How does Manila Water finance its infrastructure programme?
Manila Water funds capital expenditure through internally generated cash, long-term debt, available credit facilities, and financing from local and international institutions. Long-lived water and wastewater assets are matched with longer-term funding, while approved investment recovery operates through the concession's tariff and rate-rebasing mechanisms.
How does the concession framework support long-term investment?
The concession establishes service obligations, performance standards, regulatory review processes, and mechanisms for recovering prudent expenditure. The approved extension of the Revised Concession Agreement to January 2047 provides a longer investment horizon for source-development, network, and wastewater projects with multi-decade asset lives.
How does Manila Water maintain low non-revenue water?
The company combines district metering, network balancing, pressure management, leak detection, pipe rehabilitation, flow monitoring, and active maintenance. These measures kept East Zone non-revenue water below 14 percent at the end of 2025 while supporting continuous service across a dense metropolitan network.
Why is wastewater infrastructure a major capital priority?
Wastewater investment is required to expand sanitation coverage, meet concession commitments, and comply with environmental standards. Delivery therefore depends on coordinated investment in treatment capacity, sewer and interceptor networks, pumping facilities, land access, permitting, and connections to densely developed communities.
