Moorreesburg Wastewater Treatment Plant, Swartland Local Municipality, Western Cape

Moorreesburg wastewater treatment plant is located in the town of Moorreesburg, within the Swartland Local Municipality of the Western Cape province, South Africa. The facility serves a population of approximately 11,100 people, classifying it as a medium-sized municipal treatment plant in the region. As a South African wastewater facility, the plant operates under the national Water Services Act and the National Water Act, which set standards for effluent quality and environmental protection. For a plant of this scale, secondary treatment is typically required to meet general discharge limits, ensuring adequate removal of organic matter and suspended solids before release. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Berg River catchment, which flows into the Atlantic Ocean at Velddrif. The Berg River supports diverse aquatic life and is an important water resource for agriculture and ecosystems in the Western Cape. The plant's operation is critical for protecting downstream water quality in this semi-arid region.

The plant discharges into the Berg River catchment, which flows westward to the Atlantic Ocean near Velddrif. The Berg River supports a variety of fish and bird species and is used for irrigation and drinking water supply downstream. The Western Cape's Mediterranean climate with seasonal rainfall means that maintaining consistent treatment quality is important for protecting the river's ecological health during dry summer months.
