The Waterval wastewater care works is the biggest works operated by ERWAT and is situated in the DD6 area at the Klip River.

The first 25 Mℓ/d Module at Waterval WCW was commissioned in 1979 and subsequently modified to treat 30 Mℓ/d. Upgrades in 1989 and 1993 each added further 35 Mℓ/d capacity modules.  An upgrade during 2000/2001 included for a new inlet works comprising screens, vortex degritters, stormflow and sub-standard effluent containment measures.

The plant was originally built to serve parts of Germiston, Alberton, Kathlehong, Vosloorus and Boksburg. Due to continued and rapid growth in the southern area of Ekurhuleni, it became crucial to make provision for additional capacity at this regional wastewater treatment works.

Further extensions involved the building of a fourth activated sludge module at a cost of R170 million. The module was commissioned in 2008. The existing plant consists of a modern preliminary treatment facility, four parallel liquid biological treatment modules and tertiary disinfection before the final effluent is discharged into the Klip River.

The total design capacity of the Waterval wastewater care works is now 155 Mℓ/d.

Capacity : 155.00 Mℓ/d
