Septic tanks and drainage in Pietermaritzburg
Pietermaritzburg has a large sewered core, but suburbs on the edge, smallholdings around Ashburton and Hilton and farms in the Midlands rely on septic tanks and soakaways. The city sits in a hollow, and its clay and shale soils drain slowly, so heavy summer thunderstorms can overload drainage fields and push effluent to the surface. Schools, churches and rural clinics often run older conservancy tanks that need scheduled pump-outs. Honey sucker operators work from Mkondeni and Willowton and cover the road to Howick, while tank suppliers in the city stock plastic and concrete tanks. Sandstone outcrops can make digging a new trench slow.

Typical plastic septic tanks requests in the area come from:
- Houses: a 2,500 to 5,000 litre buried tank for a new or renovated off-sewer house
- Smallholdings and plots: a light tank that one truck can deliver to a remote building site
- Farms and game farms: tanks for worker housing and farmstalls, often delivered a long way from town
- Schools, churches and clinics: tanks for a rural school or clinic where installation must be quick
- Lodges, guesthouses and venues: larger tanks in series for chalets, with anchoring where the ground is damp
- Restaurants, shops and offices: small tanks behind a shop, restaurant or filling station, with a grease trap upstream
- Estates and complexes: a row of plastic tanks serving a few cottages or units on shared ground
