How we help in Durban

Rainwater harvesting design sizes storage, treatment, and overflow for reliability without creating uncontrolled stormwater risk. In Durban, High annual rainfall, tropical cyclone remnants, and steep coastal topography create aggressive runoff and scour potential in many catchments. Our team supports projects across KwaZulu-Natal with studies scoped for municipal and DWS review cycles.

Durban sits within KwaZulu-Natal, where eThekwini coastal management and stormwater requirements are central to approvals along the urban corridor and estuarine margins. For this service, we emphasise defensible hydrology, clear assumptions, and deliverables that integrate with your professional team—survey, civils, and environmental practitioners—so approvals move without rework.

When do you need this?

  • Commercial and industrial buildings targeting non-potable supply
  • Sites where stormwater attenuation must pair with harvesting
  • Water-sensitive precincts with dual objectives (yield + flood risk)

Methodology, deliverables, standards, and FAQs are maintained on the national service page—updated as regulations and municipal guidance evolve.
