Taman Tun Dr Ismail STP (KLR354 & KLR391) - Kuala Lumpur Wastewater Treatment Plant

Taman Tun Dr Ismail STP (KLR354 & KLR391) is an operational wastewater treatment plant located in the Taman Tun Dr Ismail suburb of Kuala Lumpur, Malaysia. The plant is part of the city's extensive sewerage network managed by Indah Water Konsortium, the national wastewater utility. It serves the local residential and commercial community, contributing to the sanitation needs of the greater Kuala Lumpur metropolitan area. The plant operates under Malaysia's regulatory framework for wastewater treatment, which is governed by the Department of Environment (DOE) under the Environmental Quality Act 1974. Treatment standards are aligned with the National Water Quality Standards for effluent discharge. For plants serving urban areas like Taman Tun Dr Ismail, secondary treatment is typically required to meet these standards. Treated effluent from the plant is discharged into the local drainage system, which eventually flows into the Klang River basin. The Klang River runs through Kuala Lumpur and empties into the Strait of Malacca. The plant plays a key role in protecting the Klang River from untreated sewage, supporting downstream aquatic life and water quality in the river and coastal waters.

The plant discharges treated effluent into the Klang River basin, which flows through Kuala Lumpur and into the Strait of Malacca. The Klang River is an ecologically important waterway that supports diverse aquatic life and provides water for various uses. Downstream, the river enters the coastal waters of the Strait of Malacca, a busy shipping channel that also supports mangrove ecosystems and fisheries. Proper treatment at this plant helps reduce nutrient and pathogen loads, protecting both freshwater and marine environments.
