Maynilad completes 2 sewage treatment plants in QC

West Zone concessionaire Maynilad Water Services Inc. (Maynilad) recently commissioned two new sewage treatment plants (STPs) on Legal and Grant Streets in Project 8, Quezon City.

The two facilities can treat up to 1,030 cubic meters per day of wastewater, which would benefit 1,685 households in the area.

These facilities—along with Maynilad’s STP at Congressional Avenue that was commissioned earlier this year—will improve sewerage services for more than 12,200 people in Quezon City and help clear the San Juan River Basin, which empties into the Manila Bay.

The wastewater generated by households and establishments in the area used to be treated by communal septic tanks, which were first constructed by the People’s Homesite and Housing Corp. in the 1950s. Maynilad invested over P91.7 million to upgrade these communal septic tanks into three new STPs.

With the help of a Sequencing Batch Reactor (SBR) technology, Maynilad was able to build an STP despite the small land area available for use in this densely populated area.

The SBR provides high-quality treatment to ensure that wastewater discharged conforms to environmental standards set by the Department of Environment and Natural Resources.

By 2013, Maynilad aims to construct a total of 15 STPs in the San Juan River Basin area with a combined capacity of around 72,000 CMD, benefiting more than 550,000 people. Five more STPs with a combined capacity of 410,000 CMD serving around 2 million people will also be built by 2016.
