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.
