Overview
Shah Alam Sewage Treatment Plant (SAM 024) is an operational facility serving the city of Shah Alam, Malaysia. It treats municipal wastewater before discharge into local waterways.
The Shah Alam Sewage Treatment Plant (SAM 024) is a key wastewater treatment facility located in Shah Alam, the capital city of Selangor state in Malaysia. It serves the urban population of this rapidly growing metropolitan area, which is part of the greater Kuala Lumpur conurbation. As an operational plant, it is subject to Malaysia's environmental regulations under the Department of Environment (DOE), which sets discharge standards for sewage treatment plants. For a plant of this scale in an urban setting, typical treatment includes secondary biological processes to meet national water quality standards. The treated effluent is discharged into local rivers that eventually flow into the Straits of Malacca, a vital shipping route and ecologically important marine environment. The plant plays a crucial role in protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant discharges into the Klang River basin, which flows through the heart of Shah Alam and Kuala Lumpur before emptying into the Straits of Malacca. This estuary and coastal zone support diverse marine life, including fisheries and mangrove ecosystems that are important for coastal protection and biodiversity.
