While Maynilad operates year-round, inspections and declogging efforts are heightened during the wet months to help prevent sewer overflows and support flood mitigation. As of June 2025, Maynilad has cleaned over 285 kilometers of sewer lines and cleared more than 3,500 sewer manholes to ensure the smooth flow of wastewater to treatment facilities.

West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) is ramping up its wastewater operations this rainy season to prevent sewer overflows and support flood mitigation, while continuing its year-round efforts to maintain a clean and efficient sewer network.

While Maynilad’s wastewater operations run year-round, the company deploys additional teams and intensifies sewer inspections and declogging activities during the rainy season to address increased risks of blockages and overflows.

These activities are especially critical in areas with combined or hybrid sewer systems, where stormwater mixes with wastewater, often bringing in trash and debris that can clog interceptor boxes, manholes, and sewer lines. Interceptor boxes are installed at the end of drainage lines to catch combined flows and divert wastewater to Maynilad’s sewer network for proper treatment.

As of June 2025, Maynilad has cleaned over 285 kilometers of sewer lines and cleared more than 3,500 sewer manholes. Preventive maintenance ensures that wastewater is conveyed properly to treatment plants and prevents sewer overflows that may worsen during heavy rains.

“Interceptor boxes are installed at the end of drainage lines to catch combined flows and divert wastewater to our sewer network for proper treatment,” explained Maynilad Wastewater Management Head Engr. Zmel D. Grabillo. “Unfortunately, these systems can get blocked by trash that’s swept into drainages during floods.”

Maynilad has prioritized combined-sewer areas such as Quezon City, Pasay, Parañaque, and Valenzuela, where more frequent maintenance is needed during the wet season.

Although Maynilad does not clean storm drains—which fall under the jurisdiction of local government units—its work in maintaining the sewer network helps ease pressure on drainage systems, indirectly contributing to flood prevention.

The company continues to coordinate with LGUs and other stakeholders to protect sewer infrastructure and ensure public health and environmental safety.

“We ask the public to be responsible with waste disposal,” added Engr. Grabillo. “Even small acts like properly segregating trash can help prevent blockages that cause flooding.”

Maynilad is the largest private water concessionaire of Metropolitan Waterworks and Sewerage System (MWSS) in the Philippines in terms of customer base. Its service area includes the cities of Manila (all but portions of San Andres and Sta. Ana), Quezon City (west of San Juan River, West Avenue, EDSA, Congressional, Mindanao Avenue, the northern part starting from the Districts of Holy Spirit and Batasan Hills), Makati (west of South Super Highway), Caloocan, Pasay, Parañaque, Las Piñas, Muntinlupa, Valenzuela, Navotas, and Malabon, all in Metro Manila; and the cities of Cavite, Bacoor, and Imus, and the municipalities of Kawit, Noveleta, and Rosario, all in the province of Cavite.

West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) now delivers piped-in water to around 10.5 million people as of the first quarter of 2025, marking continued gains in service coverage, availability, and water pressure across its concession area.

As of March 2025, the company had 1,556,603 active water service connections, covering 94.7% of the West Zone. This is up from 77.8% coverage in 2006, when Maynilad came under new management.

Water service availability and pressure have also improved significantly. Around 96.8% of customers now receive 24-hour water supply, compared to 32% in 2006. Likewise, 96.8% of customers get water at an average pressure of at least seven pounds per square inch (psi)—the minimum required to push water up to the second floor of a structure—up from 45% in 2006.

Since its re-privatization in 2007, Maynilad has replaced 3,293 kilometers of aging pipelines—equivalent to approximately 72% of its inherited pipe network—to help minimize losses and improve network reliability.

“We remain focused on expanding access and sustaining service levels as demand rises,” said Maynilad President and CEO Ramoncito S. Fernandez. “It’s a long-term commitment that supports both water security and the well-being of the communities we serve.”

Maynilad is the largest private water concessionaire in the Philippines in terms of customer base. It is the concessionaire of the Metropolitan Waterworks and Sewerage System (MWSS) for the West Zone of the Greater Manila Area, which is composed of the cities of Manila (certain portions), Quezon City (certain portions), Makati (west of South Super Highway), Caloocan, Pasay, Parañaque, Las Piñas, Muntinlupa, Valenzuela, Navotas and Malabon all in Metro Manila; the cities of Cavite, Bacoor and Imus, and the municipalities of Kawit, Noveleta and Rosario, all in Cavite Province.

This initiative is part of the company’s ongoing partnership with government efforts to improve learning environments.

Espiritu. “By helping to create safe and welcoming school environments, we hope to empower more Filipino children to grow and thrive.”
