Waters bills in areas served by Maynilad Water Servicrs Inc. are set for a modest uptick in 2026.
Effective January 1, Maynilad will implement a 2.85 percent Rate Adjustment Limit (RAL) on its existing basic charge, following the recommendation of the MWSS Regulatory Office and the approval of the MWSS Board of Trustees.
Maynilad, the country’s largest private water concessionaire by customer base, has over 1.5 million connections serving more than 10 million people, primarily in Metro Manila. It operates the West Zone of the Greater Manila Area—covering most of Manila, large portions of Quezon City and Makati, all of Caloocan, Las Piñas, Malabon, Muntinlupa, Navotas, Parañaque, Pasay, and Valenzuela, as well as Cavite City, Bacoor, Imus, and the towns of Kawit, Noveleta and Rosario. The concessionaire runs 10 business area offices across the zone.
Aside from the basic charge adjustment, customers will continue to pay an environmental charge equivalent to 25 percent of their water charge, which applies to all Maynilad customers.
On the upside, the Foreign Currency Differential Adjustment (FCDA) for the first quarter of 2026 will be set at a negative 0.42 percent of the water charge, providing a slight offset to overall billing. The FCDA reflects fluctuations in foreign exchange rates and is subject to periodic review and adjustment. Low-income lifeline customers consuming 20 cubic meters or less per month will be exempt from the FCDA.
Sewerage charges will also remain in place for customers connected to Maynilad’s sewer lines. Residential and semi-business customers will pay a sewerage charge equivalent to 20 percent of their water charge, while Business Group I and II customers will be charged 20 percent as well.
Regulators said the approved rate adjustment is intended to balance consumer protection with the need to sustain water service operations, infrastructure investments, and long-term system reliability in one of the country’s most densely populated regions.
For millions of households and businesses in the West Zone, the 2026 adjustment signals slightly higher bills—but also continued funding for water and wastewater services critical to urban growth. Maynilad has a water concession agreement with the government until 2047.
