Septic Tank Design in Johannesburg

Septic tank design in Johannesburg depends on soil, water table and municipal rules as much as household size. Tell us the number of bedrooms or users, the stand size and whether the ground is clay, sand or rock, so designers and contractors serving Johannesburg and the rest of Gauteng can propose a suitable layout.

Septic tanks and drainage in Johannesburg

Most of Johannesburg is on the municipal sewer, so septic and conservancy tanks turn up in pockets: older homes in the south, plots on the city edge such as Lanseria and Diepsloot, and commercial sites where connections never reached. Conservancy tanks serve some new developments waiting for bulk services, and tanker trips to the Goudkoppies and Olifantsvlei works are common. Rocky ridges and clay mean soakaways drain slowly in summer storms. Honey sucker operators work from the southern and western industrial areas and cover most suburbs the same day, though peak weeks after heavy rain run behind. Ask what size tank you have before booking.
