Bandar Rimbayu STP (GKL239) - Wastewater Treatment Plant in Selangor, Malaysia

Bandar Rimbayu STP (GKL239) is an operational wastewater treatment plant located in Bandar Rimbayu, a township in Selangor, Malaysia. The plant is part of the national wastewater infrastructure managed by Indah Water Konsortium, the primary sewerage operator in Malaysia. It serves the residential and commercial areas of Bandar Rimbayu, a developing satellite township within the Greater Kuala Lumpur conurbation. As a plant in Malaysia, Bandar Rimbayu STP operates under the Environmental Quality Act 1974 and the Sewerage Services Act 1993, which set effluent discharge standards for wastewater treatment. The plant is expected to provide at least secondary treatment, as mandated for urban areas in Malaysia. The plant is designed to meet the regulatory requirements for its service area. The treated effluent from Bandar Rimbayu STP is discharged into local waterways that eventually flow into the Strait of Malacca, a major shipping route and ecologically important marine environment. The plant plays a key role in protecting the water quality of rivers in the region and reducing pollution loads to the coastal ecosystem.

The plant's treated effluent enters local drainage systems that feed into the Klang River basin, which flows through Kuala Lumpur and empties into the Strait of Malacca. The Klang River is a vital waterway for the region, supporting diverse aquatic life and providing water for various uses. The downstream environment includes mangrove forests and coastal habitats that are sensitive to pollution, making effective wastewater treatment essential for maintaining ecological balance.
