Twee Riviere Wastewater Treatment Plant, Kou-Kamma Local Municipality, Eastern Cape

Twee Riviere is a wastewater treatment plant situated in the Kou-Kamma Local Municipality, within the Sarah Baartman District Municipality of South Africa's Eastern Cape province. The plant serves the local community of Joubertina and surrounding areas, operating as part of the region's municipal wastewater infrastructure. The plant employs secondary treatment, which is the standard biological treatment process required for municipal wastewater in South Africa. Under the National Water Act and relevant regulations, treatment plants of this scale are expected to meet effluent quality standards before discharge. The plant's capacity and population served are consistent with a medium-sized agglomeration typical of rural towns in the Eastern Cape. The treated effluent from Twee Riviere likely discharges into a local watercourse within the Gamtoos River catchment, which flows southward to the Indian Ocean. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's rivers and estuaries.

Twee Riviere is located inland in the Eastern Cape, within the Gamtoos River basin. The treated wastewater likely enters a tributary of the Gamtoos River, which flows into the Gamtoos Estuary and ultimately the Indian Ocean. The estuary supports diverse aquatic life and is an important habitat for migratory birds. The plant's secondary treatment helps reduce nutrient loading and protect downstream water quality.
