Taman Selayang Mulia Sewage Treatment Plant, Selayang, Malaysia

Taman Selayang Mulia Sewage treatment is an operational wastewater facility located in Selayang, a suburb in the Gombak district of Selangor, Malaysia. The plant serves the residential area of Taman Selayang Mulia and surrounding communities, contributing to the region's sanitation and environmental management. As a municipal sewage treatment plant in Malaysia, it operates under the national regulatory framework overseen by the Department of Environment (DOE) and the National Water Services Commission (SPAN). Malaysian wastewater treatment standards typically require secondary treatment for urban areas, with larger agglomerations subject to more stringent effluent quality requirements under the Environmental Quality Act 1974. The plant's treated effluent is discharged into local waterways that eventually flow into the Klang River basin, which drains into the Straits of Malacca. This river system is ecologically important, supporting diverse aquatic life and providing water resources for the densely populated Klang Valley region.

The plant discharges into the Klang River basin, a major watershed in Selangor that flows through Kuala Lumpur and empties into the Straits of Malacca. This coastal estuary supports mangrove ecosystems and serves as a critical habitat for fish and migratory birds. The receiving waters are ecologically sensitive due to urban runoff and industrial activities in the region.
