Upper Kerayong Centralised Sewerage Treatment Plant (C-STP) Taman Maluri C, Kuala Lumpur

Upper Kerayong Centralised Sewerage Treatment Plant (C-STP) Taman Maluri C is a municipal wastewater treatment facility located in Kuala Lumpur, Malaysia. It serves the Taman Maluri area, a densely populated urban suburb within the greater Klang Valley region. The plant is part of Malaysia's centralized sewerage system managed under the national Sewerage Services Act 1993. As an operational plant, it is subject to Malaysia's Environmental Quality Act 1974 and the Sewerage Services Act, which mandate treatment standards for municipal wastewater. For urban agglomerations like Taman Maluri, secondary treatment is typically required, with possible nutrient removal in sensitive catchments. The plant's design and operation align with national guidelines for population equivalents in the medium-to-large range. The treated effluent from the plant is discharged into the Kerayong River, a tributary of the Klang River system. The Klang River flows through Kuala Lumpur and ultimately drains into the Strait of Malacca. This river system supports diverse aquatic life and is a critical water resource for the region, though it faces pressures from urbanization and industrial activities.

The plant discharges into the Kerayong River, a tributary of the Klang River basin. The Klang River flows through Kuala Lumpur and empties into the Strait of Malacca, a vital marine corridor. The watershed supports diverse aquatic ecosystems and is important for local fisheries and biodiversity. Urban runoff and industrial discharges in the Klang Valley pose challenges to water quality, making effective wastewater treatment essential for protecting downstream environments.
