Bunus Regional Sewage Treatment Plant (KLR347) - Klang Valley, Malaysia Wastewater Facility

Bunus Regional Sewage Treatment Plant (KLR347) is a key wastewater treatment facility located in the Klang Valley, Malaysia, one of the country's most urbanized and populous regions. The plant plays a critical role in managing sewage from residential, commercial, and industrial sources in the greater Kuala Lumpur area. As a regional plant, it is expected to provide at least secondary treatment under Malaysian environmental regulations, which align with international standards for water quality protection. The plant's scale suggests it serves a large agglomeration, likely exceeding 150,000 population equivalent, requiring robust treatment processes to handle high volumes of wastewater. The treated effluent is discharged into local waterways that eventually flow into the Klang River and then to the Strait of Malacca. This discharge point is ecologically significant as the strait supports diverse marine life and is a vital shipping route. Proper treatment helps protect downstream ecosystems and coastal water quality.

The plant discharges into the Klang River basin, which flows through Kuala Lumpur and empties into the Strait of Malacca. This coastal environment supports mangrove forests, fish nurseries, and migratory bird species. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain the ecological health of the strait, which is also a major fishing ground.
