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 french drain requests in the area come from:
- Houses: a trench for a septic tank at an older house, or a stormwater drain along a damp wall
- Restaurants, shops and offices: stormwater trenches for parking and retail frontages, and septic trenches for rural shops
- Estates and complexes: stormwater french drains around units and communal gardens, with septic trenches where off-sewer
- Factories, mines, sites and events: drains on yards, depots and building sites where runoff would otherwise pond
- Schools, churches and clinics: long trenches for school and church septic systems, and drains keeping playgrounds dry
- Smallholdings and plots: a longer septic trench on a smallholding, plus drains that carry runoff off the yard
