Rondebult Wastewater Treatment Plant, City of Ekurhuleni, Gauteng, South Africa

Rondebult is a wastewater treatment plant located in the City of Ekurhuleni Metropolitan Municipality, Gauteng, South Africa. The facility serves a population of about 24,295, placing it in the medium-agglomeration category under South African water management frameworks. As a plant in South Africa, Rondebult operates under the national regulatory framework governed by the Department of Water and Sanitation. Plants of this scale are typically required to meet secondary treatment standards to protect water resources. The plant discharges into the local watershed, which is part of the Vaal River system. The Vaal River is a major tributary of the Orange River, ultimately draining into the Atlantic Ocean. The surrounding region is urban and industrial, making effective wastewater treatment critical for downstream water quality and ecosystem health.

Rondebult's treated effluent enters the local drainage network, which flows into the Vaal River, a key water source for the region. The Vaal River supports diverse aquatic life and is used for irrigation, industry, and drinking water downstream. The plant's location in a densely populated metropolitan area means its discharge quality directly affects the ecological health of the Vaal system and the broader Orange River basin.
