Maynilad Water Services Inc, the country’s largest water concessionaire, has budgeted P3 billion for the construction of 18 new sewage treatment plants (STP) and upgrade 17 more existing STPs over the next five years.
Its upgrade program means adding treatment processes in its aging water treatment plants to boost their nutrient-removal capacity as compliance to revised effluent standards set by the Department of Environment and Natural Resources (DENR).
Maynilad officials said that by 2027, all 22 existing STPs with a combined capacity of 684,707 cubic meters of wastewater a day will have been compliant to upgraded effluent standard.
According to Maynilad, its Paranaque STP, also its biggest, is already DENR compliant.
Maynilad’s 17-STP upgrade plan will eventually require the utility company to spend P178 billion between now and 2046 to make its wastewater treatment plants compliant.
By then, it will have built 360 kilometers of new sewer lines that will catch and transport waste water from households to STPs before these are discharged to receiving bodies of water as the Manila Bay.
Maynilad’s customer base serve the cities of Manila, Quezon City, Makati, Caloocan, Pasay, Parañaque, Las Piñas, Muntinlupa, Valenzuela, Navotas and Malabon, Cavite, Bacoor and Imus, and the towns of Kawit, Noveleta and Rosario in Cavite Province.
