The Jan Smuts WCW is situated in Brakpan and falls within the DD4 drainage district. It was built in 1938 and upgraded and extended on several occasions over a period of time. The design capacity of the works is 6.1 Mℓ/d for effluent from the Brakpan, Dalview, Dalpark and Vulcania areas. Conventional biological filtration is employed as the main treatment process.

A central inlet works incorporating the processes of screening and grit removal serves the works. The biological filtration process includes primary sedimentation, biological filtration and humus clarification. The effluent from the biological trickling filters is treated chemically to remove ortho-phosphate through the humus tanks and the humus tank effluent is filtered through the mechanical disc filtration unit (Tertiary Filtration Unit – TFU). The final effluent is chlorinated before discharging it into the Jan Smuts Dam. The outflow of the dam flows into the Blesbokspruit.
