Understanding Water Supply in Durban
Durban's water comes largely from the Mgeni system — Midmar, Albert Falls, Nagle and Inanda dams — delivered through uMngeni-uThukela Water and eThekwini's reticulation. The subtropical climate delivers heavy summer rainfall, but the city's problem has not been raw availability so much as delivery: non-revenue water losses well above the national average, and infrastructure repeatedly wrecked by flooding, most severely in April 2022 when major aqueducts failed and parts of the metro were dry for weeks.
Humidity and warmth also change the treatment picture. Biological growth in storage tanks, biofilm in dormant pipework and elevated organic loading after storm events are routine here in a way they are not inland. Coastal sites near Amanzimtoti and the Bluff face salinity in shallow groundwater, and the industrial south basin carries a legacy of hydrocarbon and heavy-metal contamination that rules out untreated shallow abstraction.

Local Conditions, Regulation & Geology
What our engineers account for when designing a water system in Durban.
Municipal Supply & Restrictions
eThekwini Municipality operates supply-side throttling and planned reservoir management rather than continuous restrictions, which in practice means scheduled overnight low-pressure periods across large parts of the metro. When dam levels drop, restriction notices follow the uMngeni system's allocation cuts.
Industrial users in the south basin must comply with eThekwini's trade effluent by-laws and the Department of Water and Sanitation's discharge conditions, with monitoring and reporting obligations attached. Fire water reserves for warehousing and port-adjacent facilities are governed by SANS 10400-W and insurer requirements, both of which we design to.
Industries We Supply in Durban
The port and its supporting logistics, chemical, automotive and paper industries define Durban's industrial water demand — high volumes, strict effluent limits and zero tolerance for a stoppage. Inland, sugar cane, timber and banana operations on the North and South Coasts need irrigation abstraction and storage sized around a wet summer and a dry winter. The beachfront hotel strip and the shopping and office complexes in Umhlanga and Gateway now treat independent water reserves as basic risk management after the 2022 outages.
Borehole Geology in Durban
Drilling around Durban usually starts in the Natal Group sandstones or the Dwyka tillite, with granite and gneiss of the Natal Metamorphic Province underlying much of the inland area towards Pinetown and Hillcrest. Sandstone fracture zones give the best yields; the tillite is notoriously tight and can deliver a dry hole a short distance from a productive one.
Depths of 60 m to 150 m are typical, and the deeply weathered saprolite profile common in KZN means generous solid casing through the upper section to stop collapse and keep surface water out. Near the coast, we keep abstraction rates conservative to avoid drawing saline water into the hole.
