Maynilad Water Services Inc. is installing 4.8 kilometers of new sewer lines in Parañaque City to expand its sewerage services in the area.
The project is slated for completion by the third quarter of 2025.
The company said in a statement on Monday the P695-million project involves the laying of sewer lines along portions of NIA avenue, Radial road and Sucat avenue, which will collect wastewater from over 35,000 residents of barangays La Huerta and San Dionisio.
Maynilad said the wastewater will then be conveyed to Maynilad’s Parañaque water reclamation facility for proper treatment before being safely discharged into the Kayboboy River, in compliance with environmental standards.
The company said the project was started in 2021.
“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. These require precise engineering and careful excavation,” said Zmel Grabillo, Maynilad wastewater management head.
To minimize disruption, Maynilad uses trenchless technology which allows the insertion of sewer pipes without the need for extensive surface digging.
“This method reduces traffic congestion and disturbance to the community, as pipe-laying works can be done through small insertion points,” Grabillo said.
Maynilad restricted the construction to nighttime hours between 10 p.m. and 4 a.m. with all trenches safely covered during the day to keep roads accessible to motorists and pedestrians.
Beyond Parañaque, Maynilad continues to lay its sewerage network in key cities such as Manila, Muntinlupa, Valenzuela, Bacoor, Las Piñas, Caloocan and Quezon City.
As part of its ongoing wastewater infrastructure development, the company has allotted P19 billion from 2023 to 2027 for the installation of 121 kilometers of new sewer lines across its service area.
Currently, Maynilad operates and maintains a sewer network spanning 651 kilometers and 23 wastewater facilities, with a combined treatment capacity of 684 million liters per day that form part of the company’s commitment to protecting water bodies and improving sewerage and sanitation services for its customers.
