Septic tanks and drainage in KwaZulu-Natal
KwaZulu-Natal has a humid, wet climate, steep hills and a high water table near the coast, all of which strain septic systems. Outside Durban and Pietermaritzburg's sewered areas, rural homesteads, smallholdings in the Midlands and Hillcrest area, and lodges along the Drakensberg and the North and South Coasts use septic tanks, conservancy tanks and package plants. Coastal sand floods soakaways in heavy summer rain, so many properties use sealed conservancy tanks instead. Sugar cane and timber farms add worker housing tanks, and industrial sites around Durban and Richards Bay need bulk removal. Honey sucker operators and tank suppliers work from greater Durban, Pietermaritzburg and Richards Bay.

Typical sewage treatment plants requests in the area come from:
- 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
- Smallholdings and plots: a small plant for a large smallholding with several homes and heavy use
- Estates and complexes: a package plant for a whole estate, with treated water used on common gardens
- Farms and game farms: a plant for worker housing and a packhouse, with treated water for irrigation
- 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
Local tips for KwaZulu-Natal
In KwaZulu-Natal, the most common systems are sealed conservancy tanks on the coast, septic tanks with soakaways in the Midlands. Operators and suppliers mostly work from operators based in greater Durban, Pietermaritzburg and Richards Bay. A useful tip: ask for a vacuum tanker with a licensed tipping point, not a roadside dump.
Sewage Treatment Plants usually means aerated plant: activated sludge or MBBR, for 5 to 500 kL a day, built to suit, serviced monthly, sludge removed as needed. Ground in the area: high water table near the sea and heavy summer rain: soakaways flood quickly.
What to include in your request
- Daily flow in kilolitres, or the number of users
- Where treated water will go: irrigation, dam or river
- Power supply on site, or a generator or solar
- Plant type preferred: activated sludge, MBBR or open
- Whether you need servicing and sampling after commissioning
