Indah Water Konsortium (Unit Klang) Wastewater Treatment Plant, Klang, Malaysia

Indah Water Konsortium (Unit Klang) is a wastewater treatment plant located in Klang, Selangor, Malaysia. As part of the national sewerage system, it serves the urban and industrial areas of Klang, one of the country's major cities. The plant is operated by Indah Water Konsortium, the national sewerage company responsible for wastewater management in Malaysia. However, as a facility under Malaysia's national sewerage system, it is expected to comply with the Environmental Quality Act 1974 and the Sewerage Services Act 1993. Treatment levels typically include secondary or tertiary processes depending on the discharge standards set by the Department of Environment (DOE). The treated effluent is discharged into local waterways that drain into the Klang River, which flows through the Klang Valley and ultimately into the Strait of Malacca. The Klang River basin supports diverse aquatic life and is an important ecological corridor, though it faces pressures from urbanization and industrial activities.

The plant discharges into the Klang River basin, which flows through the Klang Valley and empties into the Strait of Malacca. This coastal estuary supports mangrove ecosystems and serves as a nursery for marine species. The river is ecologically sensitive due to urban runoff and industrial discharges, making proper wastewater treatment critical for downstream water quality and biodiversity.
