Septic tanks and drainage in Stellenbosch
Stellenbosch town and Technopark are sewered, but wine estates, smallholdings along the Helderberg slopes, Jonkershoek and the Franschhoek road rely on septic tanks and conservancy tanks. Soils range from Table Mountain sandstone and granite on the slopes to heavier clay in the valley, so drainage field design varies widely. Winter rain raises the water table in low-lying wine blocks, and tasting rooms and weddings create peaks that overload small tanks. Student housing and guesthouses in town also need regular servicing. Honey sucker operators work from Stellenbosch, Somerset West and Bellville, and estates often keep a contract. Always check the disposal destination.

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
- Lodges, guesthouses and venues: a plant sized for peak guest numbers, reusing water on lawns in dry regions
- 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
- 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
- Schools, churches and clinics: a plant for a boarding school, clinic or hospital with steady, large flows
