West zone concessionaire Maynilad Water Services, Inc. is undertaking a major sewerage expansion in Parañaque City, laying 4.8 kilometers of new lines to serve over 35,000 residents in Barangays La Huerta and San Dionisio.
The P695-million initiative, extending along NIA Ave., Radial Road and Sucat Ave., will transport wastewater to Maynilad’s Parañaque Water Reclamation Facility for proper treatment, ensuring safe discharge into the Kayboboy River following environmental standards.
“Sewerage projects are highly complex and take time, as new sewer lines must be laid deeper than water pipelines—sometimes as deep as 14 meters below ground. This requires precise engineering and careful excavation,” said Maynilad wastewater management head Zmel Grabillo.
The project, which started in 2021, is expected to be completed by the third quarter of 2025.
Maynilad is using trenchless technology to minimize disruptions, reducing surface digging and thus minimizing traffic and community impact.
Construction is limited to nighttime hours, with trenches safely covered during the day to maintain road access.
Maynilad is also expanding its sewer network across Manila, Muntinlupa, Valenzuela, Bacoor, Las Piñas, Caloocan, and Quezon City.
Backed by a P19 billion budget from 2023 to 2027, Maynilad plans to install 121 kilometers of new sewer lines across its service areas, strengthening its 651-kilometer sewer network and enhancing its 684-million-liters-per-day treatment capacity.
