Manila Water is carrying out maintenance work at its Marikina North sewage and terminal pumping station to ensure service reliability and strict compliance with the environmental standards set by the Department of Environment and Natural Resources.
Part of the project involves the installation of additional sewage submersible pumps, nominal diameter pipes, and a full-bore electro-magnetic flow meter which will boost redundancy and increase plant capacity, ensuring continuous wastewater treatment even during peak flow periods.
Electrical upgrades were also implemented, including the installation of an auxiliary supply and control transformer, a motor isolator and disconnect switch, and the integration of new soft starters with the existing Supervisory Control and Data Acquisition (SCADA) system.
The project is scheduled for completion by October this year.
“Manila Water believes these improvements in our wastewater services will not just be beneficial for our customers but also to our waterways. Upgrading the efficiency of our wastewater treatment plants will ensure our effluent water will not harm the health of our rivers,” Corporate Communication Affairs Group director Jeric Sevilla.
In June, Manila Water’s 26 wastewater facilities all achieved a 100% score in wastewater effluent quality compliance to MWSS Regulatory Office’s scorecard relative to the applicable General Effluent Standards set in the issued Wastewater Discharge Permits to the treatment facilities by either Environmental Management Bureau of the Department of Environment and Natural Resources (EMB-DENR) or the Laguna Lake Development Authority (LLDA). This exceeds the 95% target for this indicator.
The company’s wastewater treatment plants produce “Class C” effluent with eliminated bio-nutrients. This is deemed safe for water recycling for non-contact purposes such as toilet flushing, cleaning, and irrigation, as well as safe for discharge to water bodies and marine life.
