Maynilad funnels P695 million for sewer line expansion

MANILA, Philippines — West Zone concessionaire Maynilad Water Services Inc. is investing P695 million for the expansion of sewerage services in Parañaque City.

Maynilad said it is currently installing 4.8 kilometers of new sewer lines along the portions of NIA Avenue, Radial Road and Sucat Avenue to improve wastewater collection from over 35,000 residents of Barangays La Huerta and San Dionisio.

“The wastewater will 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, which began in 2021, is expected to be completed by the third quarter of next year, the firm said.

“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 Zmel Grabillo, Maynilad’s Wastewater Management head.

To minimize disruption, Maynilad said it is utilizing trenchless technology that allows the insertion of durable 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 explained, adding that the construction is being done only between 10 p.m. and 4 a.m.

Maynilad has earmarked P19 billion from 2023 until 2027 for the installation of 121 kilometers of new sewer lines across its service area.

Currently, the water utility firm operates and maintains a sewer network spanning 651 kilometers and 23 wastewater facilities, with a combined treatment capacity of 684 million liters per day.

Maynilad is the largest private water concessionaire in the country in terms of customer base. It serves as the concessionaire of the Metropolitan Waterworks and Sewerage System for the West Zone of the Greater Manila Area.
