Septic Tank Design in Pretoria

Septic tanks and drainage in Pretoria

Pretoria spreads over a lot of ground the sewer network never reached. Smallholdings around Mooikloof, Zwavelpoort, the east and the north towards Roodeplaat rely on septic tanks and soakaways, while older homes in Tshwane suburbs may still have conservancy tanks. The east has expansive clay that holds water around a soakaway, and the Magaliesberg foothills are shallow and rocky. Parts of the south sit on dolomite, where leaking tanks can cause problems below the surface. Honey sucker operators and drain contractors work from Silverton, Waltloo and Pretoria West and reach most plots the same day, though long hose runs on big holdings may add time.
