Septic tanks and drainage in Sandton
Sandton is largely on the sewer, so septic work here is specific: older Bryanston and Sunninghill homes, large properties in Hyde Park and Dainfern's fringe that still use conservancy tanks, and offices or restaurants that need grease trap and drain service. Some newer estates in Fourways and Lonehill use their own treatment plants with scheduled maintenance. Water tables rise after heavy rain, and tree roots are a frequent cause of blocked drain lines on mature properties. Honey sucker and drain-cleaning operators are based in Wynberg, Marlboro and Midrand and reach most suburbs the same day. Always ask for a service report that notes tank size and condition.

Typical sewage treatment plants requests in the area come from:
- Houses: rarely used at a house; a septic tank or biodigester is normally enough
- Estates and complexes: a package plant for a whole estate, with treated water used on common gardens
- Restaurants, shops and offices: a plant for a mall, hotel or filling station away from the sewer network
- Lodges, guesthouses and venues: a plant sized for peak guest numbers, reusing water on lawns in dry regions
- Schools, churches and clinics: a plant for a boarding school, clinic or hospital with steady, large flows
- Factories, mines, sites and events: a plant for a mine camp or factory, with sampling and waste records
