The plant is part of the Manila Water concession, which provides water and wastewater services to the eastern part of Metro Manila. As a sewage treatment plant in the Philippines, it operates under the national Clean Water Act (Republic Act 9275), which mandates wastewater treatment for all sources.

Environmental context
The plant discharges into the Pasig River, which flows through Metro Manila and empties into Manila Bay. Manila Bay is a semi-enclosed estuary that supports diverse aquatic life, including mangroves, seagrasses, and fisheries. The bay is ecologically sensitive due to high nutrient loads from urban runoff and untreated wastewater, making advanced treatment crucial for preventing eutrophication and protecting marine biodiversity.
