West Zone concessionaire Maynilad Water Services Inc. is planning to spend approximately P178 billion until 2046 to fund its wastewater management program to help manage water pollution.

The Pangilinan-led company said the allocation will cover the construction of 18 new Sewage Treatment Plants across its concession area.

Likewise, it will finance the installation of around 360 kilometers of new sewer lines that will catch and convey used water from households to STPs as well as the upgrade of 17 existing wastewater facilities.

“Besides improving the distribution of drinking water supply, our investment program also includes the laying of essential infrastructure to collect and treat the wastewater generated by households so we can ensure environmental sustainability,” Maynilad chief operating officer Randolph T. Estrellado.

Revised effluent standards

Maynilad, thus, committed to meeting the revised effluent standards of the Department of Environment and Natural Resources in implementing all its wastewater-related projects.

Currently, Maynilad is constructing new STPs and laying sewer conveyance systems in Valenzuela, Caloocan, Las Piñas and Muntinlupa.

Once operational, the combined capacities of these new facilities can treat 419 million liters of wastewater per day — serving around 1.75 million residents.
