A multimillion rand wastewater treatment facility augmentation is 98% complete. The upgrading and augmentation of the Johannesburg Water’s Olifantsvlei Wastewater Treatment Works Module-3 in southern part of the City of Johannesburg is finally nearing completion. The augmentation from the current capacity of 180 megalitres per day by 50 megalitres per day is intended to cater for increased growth in demand from population, higher densification, and will service an additional 50 000 new housing units as well as meet the stringent treated effluent compliance standards to mitigate contamination of streams and rivers in the catchment area. The cost of the upgrading is in order of R170 million and consists of an activated sludge reactor, mixers aerators, recycling pumps, a flow divider, three clarifiers, a pump station, three electrical rooms, a monitoring building, inter-connecting pipework, paved roads, storm water drains and cable trenches.
