Septic tanks and drainage in Durban
Most of Durban is on the municipal sewer, so septic and conservancy tanks matter in the pockets that are not: older homes on the Bluff and in parts of Westville, new developments on the northern and western edges, and plots in Hillcrest and Waterfall. Sandy coastal ground and a high water table mean soakaways saturate quickly after summer storms, and many sites use sealed conservancy tanks instead. Restaurants and hotels along the beachfront and in Umhlanga need regular grease trap and tank clearing. Honey sucker operators work from the southern basin, Pinetown and the North Coast, and the municipal works accepts loads at designated disposal points.

Typical sewage treatment plants requests in the area come from:
- 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
- Restaurants, shops and offices: a plant for a mall, hotel or filling station away from the sewer network
- Lodges, guesthouses and venues: a plant sized for peak guest numbers, reusing water on lawns in dry regions
- Factories, mines, sites and events: a plant for a mine camp or factory, with sampling and waste records
- Smallholdings and plots: a small plant for a large smallholding with several homes and heavy use
- Schools, churches and clinics: a plant for a boarding school, clinic or hospital with steady, large flows
Local tips for Durban
Common here: conservancy tanks on high water table sites, septic tanks with soakaways inland. Ask each operator or contractor to allow for this: ask for the disposal slip from the eThekwini works as proof of legal dumping. Help usually comes from operators in Prospecton, Pinetown and along the North Coast.
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: sandy coastal soil and a high water table: soakaways flood after storms.
