MWSS admits only 22% of Maynilad, Manila Water service areas have sewerage
The state of wastewater treatment in Metro Manila.
In a message see Metro Manila Water Works and Sewerage System (MWSS) on Wednesday welcomed the Senate?s move to conduct an inquiry on thnt to the Philippine News Agency (PNA), MWSS Administrator Rey V. Velasco reaffirmed the agency?s commitment to carry out its mandate and responsibilities as stipulated in Republic Act No. 9275, or the Philippine Clean Water Act, following the filing of Senate Resolution 747 by Senate committee on environment and natural resources chairperson, Senator Cynthia A. Villar, to conduct an inquiry on the state of wastewater treatment in Metro Manila.
Velasco assured that MWSS was ?continuously working with our concessionaires — Manila Water and Maynilad — to find ways to speed up the establishment of additional sewerage treatment plants in Metro Manila.?
Velasco admitted that Maynilad and Manil Water only covered 22 percent of their concession area.
Velsaco said both have committed to achieve full coverage within the duration of their respective concession agreements.
Velasco was confident the probe would put to rest allegations that ?there is failure of implementation and enforcement of laws with respect to the provision of adequate sanitation, drainage and sewer facilities in Metro Manila.
MWSS recently unveiled a wastewater management facility of Maynilad in Pasay City that can process up to 46.6 million liters of wastewater per day.
With this new facility, Metro Manila now has 58 wastewater treatment facilities.
Velasco said that Maynilad, which covers Metro Manila’s West Zone, maintains and operates 17 sewage treatment plants (STPs), two combined sewage and septage treatment plants and one septage treatment plant that process wastewater and sludge collected from customers.
Nineteen of its STPs in Muntinlupa, Caloocan, Manila and Quezon City earned for the company ISO certifications in quality, environment, and safety and health management.
For Manila Water, its water sewerage service includes the operation and maintenance of networks of sewer pipelines that collect and convey sewage to sewage treatment plants.
Its sanitation service likewise involves the operation and maintenance of vacuum trucks that clean or de-sludge household septic tanks, and septage treatment plants that receive and treat the hauled septage before disposing of the treated byproducts (treated wastewater and bio-solids) through environment-safe means.
For Manila Water’s concession area that is not connected to a sewerage system, wastewater is disposed into septic tanks.
Because septic tanks provide only primary treatment, they eventually leak out pollution into the groundwater or into municipal drainage systems, eventually finding its way into the rivers. (PNA)
