Overview
Manila Water - LKK Sewage Treatment Plant serves the Philippines capital region, treating municipal wastewater before discharge. The plant is operational and part of Manila Water's network.
Manila Water - LKK Sewage Treatment Plant is a municipal wastewater facility located in the Philippines, serving the greater Manila area. The plant is operated by Manila Water, the concessionaire for the East Zone of Metro Manila, and plays a key role in managing wastewater from one of the most densely populated urban regions in the world. As a plant under Philippine regulations, it is subject to the Clean Water Act of 2004 (Republic Act 9275), which mandates wastewater treatment standards and discharge permits through the Department of Environment and Natural Resources (DENR). For large metropolitan areas like Metro Manila, secondary treatment is typically required to protect receiving waters. The plant discharges treated effluent into the Pasig River system, which flows into Manila Bay, a critical water body supporting fisheries, transport, and biodiversity. Manila Bay is ecologically sensitive due to pollution loads from the metropolis, making proper wastewater treatment essential for water quality and public health.
Environmental context
The plant's treated effluent enters the Pasig River, which drains into Manila Bay, a semi-enclosed estuary connected to the South China Sea. Manila Bay supports diverse aquatic life and is an important fishing ground, but faces eutrophication and pollution pressures from urban runoff and untreated wastewater. Effective treatment at this plant helps reduce nutrient and pathogen loads, contributing to the bay's ecological recovery and safe recreational use.
