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.

Typical soakaway requests in the area come from:
- Houses: a new or rebuilt soakaway for an older house whose pit has clogged or flooded
- Restaurants, shops and offices: pits for rural shops, filling stations and restaurants that are not on a sewer
- Estates and complexes: sizing pits for shared tanks on a complex, with a test report for the body corporate
- Factories, mines, sites and events: pits for site offices, depots and ablutions, sized for the number of workers
- Schools, churches and clinics: large pits for schools, clinics and churches, designed for heavy daytime use
- Smallholdings and plots: a larger pit or two linked pits on a smallholding with space but heavy clay soil
