Septic tanks and drainage in Welkom
Welkom is a goldfields town of wide streets and traffic circles, with most of the suburbs, such as Riebeeckstad and Bedelia, on the sewer. As mines have closed, ageing pipes and pumping stations cause blockages and spills, and some areas depend on septic or conservancy tanks. Smallholdings and farms toward Odendaalsrus, Virginia, Hennenman and Allanridge use septic tanks. The flat landscape has shallow pans, and the ground holds water after summer storms. Sandy loam and clay layers vary from plot to plot, so soakaway tests are worthwhile. Honey sucker operators work from Welkom and Odendaalsrus, and mine and school sites need regular scheduled service.

Typical sewage treatment plants requests in the area come from:
- Houses: rarely used at a house; a septic tank or biodigester is normally enough
- Smallholdings and plots: a small plant for a large smallholding with several homes and heavy use
- Schools, churches and clinics: a plant for a boarding school, clinic or hospital with steady, large flows
- Farms and game farms: a plant for worker housing and a packhouse, with treated water for irrigation
- Restaurants, shops and offices: a plant for a mall, hotel or filling station away from the sewer network
- Factories, mines, sites and events: a plant for a mine camp or factory, with sampling and waste records
- Estates and complexes: a package plant for a whole estate, with treated water used on common gardens
