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 plastic septic tanks requests in the area come from:
- Houses: a 2,500 to 5,000 litre buried tank for a new or renovated off-sewer house
- Smallholdings and plots: a light tank that one truck can deliver to a remote building site
- Schools, churches and clinics: tanks for a rural school or clinic where installation must be quick
- Farms and game farms: tanks for worker housing and farmstalls, often delivered a long way from town
- Restaurants, shops and offices: small tanks behind a shop, restaurant or filling station, with a grease trap upstream
- Factories, mines, sites and events: tanks for site offices and ablutions on construction sites and small works
- Estates and complexes: a row of plastic tanks serving a few cottages or units on shared ground
