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 septic tank design requests in the area come from:
- Houses: sizing a tank by bedrooms for a new house or an extension that adds bathrooms
- Estates and complexes: a design for shared tanks or one tank per unit, to meet the estate rules
- Restaurants, shops and offices: layouts for kitchens and staff toilets that add fat and a heavier load
- Factories, mines, sites and events: temporary or permanent tank layouts for site offices, camps and workshops
- Smallholdings and plots: a larger tank and field layout for a smallholding with several buildings
- Lodges, guesthouses and venues: sizing for peak guest numbers and laundry, often with a treatment plant
- Farms and game farms: separate designs for the farmhouse and worker housing with different loads
- Schools, churches and clinics: large multi-chamber tanks for schools and clinics, with signed drawings
Local tips for Cape Town
Most work in Cape Town is done by teams based in operators in Epping, Montague Gardens and across the Cape Flats, and the usual setup is conservancy tanks on the Cape Flats, septic tanks with soakaways on mountain slopes. When you ask for quotes, ask for a pump-out before winter if your tank sits in low-lying sandy ground.
Septic Tank Design usually means size by load, split into 2 or 3 chambers, for 2,500 to 10,000 L for homes and small sites, design once, before the tank is bought. Ground in the area: sandy Cape Flats with a high winter water table: soakaways flood.
What to include in your request
- Number of bedrooms and people who use the system
- Any guest rooms, staff housing or business use
- Stand size and where the house drain leaves the building
- Soil type, slope and whether the water table is high
- Whether you need drawings for municipal approval
