Septic tanks and drainage in eMalahleni
Much of eMalahleni sits on the municipal sewer, but the town's growth has outrun the network in places. Older suburbs such as Del Judor and Tasbet Park rely on mains, while smallholdings and farms toward Ogies, Clewer and Kriel use septic tanks with soakaways or conservancy tanks. Heavy Highveld clay and shallow ground undermined by old coal workings slow drainage, so soakaways clog and tanks fill sooner than owners expect. Mining contractors, construction camps and transport depots along the N4 and N12 use bulk tanks and portable toilets. Honey sucker operators serve the area from the town and the industrial zones, and disposal usually goes to a municipal works.

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
- Smallholdings and plots: a larger tank and field layout for a smallholding with several buildings
- Factories, mines, sites and events: temporary or permanent tank layouts for site offices, camps and workshops
- Farms and game farms: separate designs for the farmhouse and worker housing with different loads
- Restaurants, shops and offices: layouts for kitchens and staff toilets that add fat and a heavier load
- Estates and complexes: a design for shared tanks or one tank per unit, to meet the estate rules
- Schools, churches and clinics: large multi-chamber tanks for schools and clinics, with signed drawings
