Tsakane WCW was initially designed with a treatment capacity of 10.8 Mℓ/d in 1975. A central inlet works, incorporating the process of screening and grit removal serves the works. HYBACS Technology (SMART UNITS) was added during 2017 to expand the capacity of the plant to 20 Ml/d ADWF.HYBACS comprises of two biological stages: a unique attached growth reactor referred to as a SMART TM unit, and a BNR activated sludge reactor.

The subsequent process is clarification (or another solids separation technique) and, crucially, some or all of the return activated sludge (RAS) is recycled to the SMART TM unit. After the BNR follows the final clarification stage. The final effluent is chlorinated before discharging into a tributary of the Blesbokspruit.
