Dimbaza Wastewater Treatment Plant, Eastern Cape, South Africa

Dimbaza wastewater treatment plant is located in the Buffalo City Metropolitan Municipality, Eastern Cape, South Africa, serving a population of about 48,279. The plant is situated inland, more than 50 km from the coast, and plays a key role in managing municipal wastewater for the Dimbaza area. As a medium-sized agglomeration, the plant is expected to meet South Africa's national water quality standards under the National Water Act (Act 36 of 1998) and the Water Services Act (Act 108 of 1997). These regulations require appropriate treatment to protect water resources, typically secondary treatment or better for inland plants discharging to freshwater systems. The treated effluent from Dimbaza plant ultimately flows into the Buffalo River catchment, which drains into the Indian Ocean via the Buffalo River estuary near East London. The river supports diverse aquatic life and is important for local communities and agriculture downstream.

The plant discharges into the Buffalo River catchment, which flows through the Eastern Cape and reaches the Indian Ocean at the Buffalo River estuary near East London. This watershed supports a variety of freshwater species and provides water for irrigation and domestic use. Protecting water quality in this system is critical for maintaining ecological balance and public health in the region.
