The Ilugin Sewage Treatment Plant (STP) is MWSS Regulatory Office’s STP of the Week.

Manila Water’s Ilugin STP is part of the North and South Pasig Sewerage System Project. It collects and treats the sewage flows of Pasig City, and portions of Mandaluyong City and Quezon City.

Wastewater from households and other establishments are collected and treated by STPs to remove contaminants before it is released back into the environment.

The treatment involves processes that change the physical, chemical or biological, and radiological composition of wastewater to reduce or prevent pollution.

The MWSS RO monitors the compliance of these STPs with the national standards on wastewater treatment to protect the health and safety of the public and the environment, especially our water resources.

Protect your health and the environment through sewage and septage management!
