Metro Manila’s two water concessionaires are exploring a supply-sharing arrangement that could allow one company to augment the other’s resources during emergencies as the threat of a strong El Niño raises concerns over water security.
The Metropolitan Waterworks and Sewerage System Regulatory Office (MWSS-RO) confirmed that Manila Water and Maynilad Water Services Inc. are discussing a possible agreement to transfer supplies between their respective service areas when demand or shortages warrant intervention.
MWSS-RO chief regulator Patrick Lester Ty disclosed the negotiations during a Senate budget hearing on Monday, saying Manila Water’s excess capacity could help provide Maynilad with an additional supply buffer.
Manila Water corporate communications head Dittie Galang said protocols for cross-border transfers are already in place, citing previous arrangements that allowed either concessionaire to benefit when the other faced greater demand.
She emphasized that any agreement must not undermine Manila Water’s ability to serve its existing customers, particularly as the country prepares for the effects of a strong El Niño.
Maynilad, however, clarified that no finalized agreement was ready for announcement. The company said it would disclose developments when appropriate.
Both concessionaires rely heavily on Angat Dam, with Manila Water serving Metro Manila’s East Zone and Maynilad operating in the West Zone. Sharing resources across these service boundaries could provide an additional measure of protection when localized supply pressures arise.
Ty said regulators are also exploring similar arrangements involving water resources in Laguna and Bulacan. He cited an existing bulk water supply agreement serving several water districts in Rizal as an example of cooperation within Manila Water’s concession area.
The proposed deal remains under discussion, with the companies yet to announce a finalized agreement. Its implementation would depend on ensuring that transfers can be made without compromising service to their respective customers.
Both concessionaires have said they are strengthening their water resources in preparation for El Niño, as authorities and utilities seek measures to protect supply reliability during potential emergencies.
