Manghwazi WWTW bio disc - Secondary Wastewater Treatment in Bushbuckridge, Mpumalanga

Manghwazi WWTW bio disc is a wastewater treatment plant located in Ward 9, Bushbuckridge, within the Ehlanzeni District of Mpumalanga, South Africa. The plant serves a small population of 444 residents, reflecting its role in a rural or peri-urban community. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. In South Africa, wastewater treatment works are regulated under the National Water Act (Act 36 of 1998) and the Water Services Act (Act 108 of 1997), which set effluent quality standards. For small plants like this, secondary treatment is typically sufficient to meet discharge requirements. The treated effluent is discharged into local watercourses that eventually drain into the Olifants River system, a major tributary of the Limpopo River. The Olifants River flows through the Kruger National Park and into Mozambique, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream.

The plant discharges into the Olifants River catchment, which flows through the Kruger National Park and into the Limpopo River basin. This watershed supports a variety of aquatic life, including fish species such as tigerfish and tilapia, and provides water for irrigation and domestic use. The downstream environment is ecologically sensitive, with seasonal wetlands and floodplains that rely on consistent water quality.
