Klawer Wastewater Treatment Plant, Matzikama Local Municipality, Western Cape

Klawer wastewater treatment plant is located in the town of Klawer, within the Matzikama Local Municipality in the Western Cape province of South Africa. The plant serves a population of approximately 4,810 residents, making it a small-scale municipal facility in the West Coast District Municipality area. The plant operates with secondary treatment, which is the standard biological treatment level required for municipal wastewater in South Africa under the National Water Act (Act 36 of 1998) and the Water Services Act (Act 108 of 1997). For small agglomerations like Klawer, secondary treatment is typically sufficient to meet effluent quality standards before discharge. The treated effluent from the plant is discharged into the local environment, likely into a nearby river or stream that drains into the Atlantic Ocean via the Olifants River system. The Western Cape region is known for its water scarcity and sensitive aquatic ecosystems, making proper wastewater treatment crucial for protecting downstream water quality and biodiversity.

The plant discharges into the Olifants River catchment, which flows through the semi-arid Western Cape region before reaching the Atlantic Ocean near Lutzville. The Olifants River supports diverse aquatic life and is an important water source for agriculture and communities. Downstream ecosystems include estuarine habitats at the river mouth, which are ecologically sensitive and rely on adequate water quality from upstream sources.
