Septic tanks and drainage in Western Cape
The Western Cape has a mix of sewered suburbs and many properties on tanks. Winter rain and a high water table on the sandy Cape Flats, West Coast and Overberg make soakaways unreliable, so conservancy tanks and treatment plants are common. Wine and fruit farms around Stellenbosch, Paarl, Worcester and Ceres use septic tanks, french drains and plants that struggle during harvest season peaks. Garden Route homes and lodges in George, Knysna and Plettenberg Bay sit on wet, steep ground near estuaries and lagoons, where regulators watch discharge closely. Honey sucker operators and tank suppliers work from Montague Gardens, Bellville, Paarl and George.

Typical sewage treatment plants requests in the area come from:
- Farms and game farms: a plant for worker housing and a packhouse, with treated water for irrigation
- Houses: rarely used at a house; a septic tank or biodigester is normally enough
- Lodges, guesthouses and venues: a plant sized for peak guest numbers, reusing water on lawns in dry regions
- Estates and complexes: a package plant for a whole estate, with treated water used on common gardens
- Smallholdings and plots: a small plant for a large smallholding with several homes and heavy use
- 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
- Schools, churches and clinics: a plant for a boarding school, clinic or hospital with steady, large flows
