West zone concessionaire Maynilad Water Services Inc. said Wednesday it earmarked P178 billion from 2023 to 2046 for its wastewater management program which aims to expand sewer coverage and manage pollution loading into bodies of water.
The water firm said in a statement the latest spending plan involves the construction of 18 new sewage treatment plants in different areas within its concession, installation of around 360 kilometers of new sewer lines that will catch and convey used water from households to STPs and the upgrade of 17 wastewater facilities to meet the revised effluent standards of the Department of Environment and Natural Resources.
“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,” said Maynilad chief operating officer Randolph Estrellado.
The company announced P3.2 billion in capital expenditure for the construction of four modular treatment plants that will serve customers in Cavite.
The four ModTPs in the cities of Bacoor and Imus in Cavite province will have a combined water output of 47 million liters per day—enough to supply the daily needs of some 200,000 customers in the area.
The investment will also cover the cost of pipelines that will distribute treated water to nearby areas. The plants are expected for completion by 2023 and 2024.
ModTPs are among the small-scale treatment plants that form part of Maynilad’s service enhancement program which aims to address water security challenges.
Maynilad is constructing new STPs and laying sewer conveyance systems in Valenzuela, Caloocan Las Piñas and Tunasan and Cupang in Muntinlupa. Combined treatment capacities of the plants are expected to reach 419 million liters of wastewater per day to serve 1.75 million residents in the area.
Then company will also construct a 140-MLD STP and new sewer lines in Manila.
Maynilad said that since 2007, it had spent P41.2 billion in capital expenditures for wastewater management projects, enabling it to add 20 STPs to the existing two and expand sanitation service with its construction of new septage treatment plants and purchase of new vacuum trucks for septic tank desludging activities.
