Septic tanks and drainage in Cape Town
Cape Town has an extensive sewer, but off-sewer areas are many: Kommetjie, Noordhoek, Hout Bay's upper slopes, Philippi horticultural area, Joostenberg and the Atlantic coast farms rely on septic tanks and conservancy tanks. Sandy soils on the Cape Flats mean a high winter water table, so soakaways flood in the wet months and sealed tanks are common. Granite and shale on the mountain slopes can need rock breaking. Industrial areas such as Montague Gardens and Paarden Eiland use grease traps and conservancy tanks. Honey sucker operators serve the metro from Epping, Montague Gardens and the Cape Flats, and portable toilet hire is busy at events.

Typical biodigesters requests in the area come from:
- Houses: a compact digester that replaces an old septic tank at an off-sewer house
- Estates and complexes: a shared digester for a small cluster, with approval from the body corporate
- Restaurants, shops and offices: a small unit for a roadside shop or office that is far from a sewer
- Factories, mines, sites and events: a site unit for staff ablutions at a quarry, depot or remote works
- Smallholdings and plots: a larger digester with biogas for the kitchen and treated water for the garden
- Lodges, guesthouses and venues: a digester sized for seasonal guest numbers, paired with a filter bed
- Farms and game farms: digesters for worker housing, sometimes fed with manure to raise biogas output
- Schools, churches and clinics: a digester for a rural school or clinic where pump-out trucks are far away
