The Asian Development Bank (ADB) has invested USD145 million in Maynilad Water Services Incorporation to expand water supply capacity and improve wastewater services across Metro Manila. The commitment—made as part of Maynilad’s IPO on the Philippine Stock Exchange—positions ADB as one of the two lead cornerstone investors in the listing.
The investment will support major upgrades to the capital region’s water infrastructure, including new treatment capacity, network modernisation, and loss-reduction measures. Funds will also strengthen sewerage and sanitation services by adding sewer lines, lift and pump stations, and interceptor systems, alongside facility upgrades and technology improvements. These measures aim to increase coverage, enhance climate resilience, and address long-standing service gaps in rapidly growing and densely populated parts of the West Zone.
ADB noted that the initiative will improve reliability, public health standards, and economic productivity for communities across Maynilad’s service area, which spans parts of 11 Metro Manila cities and several localities in Cavite with a combined population of about 10.5 million. The investment draws USD100 million from ADB’s ordinary capital resources and USD45 million from the LEAP 2 fund, which supports sustainable private-sector infrastructure projects across Asia.
