The Flood Specialists
Flood risk intelligence and water engineering for South Africa
Delta Hydro Engineers (Pty) Ltd helps insurers quantify flood exposure, supports developers, mines, and municipalities with defensible flood and stormwater work, and builds the custom software that water teams actually use.
Three pillars, one practice
We are a hydrology and hydraulics practice that does three things — and is honest about which of them are services delivered by our team today, and which are platforms we are still building.

Sectors and standards
Who our consulting work serves
Greenfield and infill residential and commercial developers, open-pit and underground mining houses, district and metropolitan municipalities, roads and rail environments, and consulting firms that need specialist hydrology or hydraulic modelling capacity on a sub-consultancy basis.
South African context
Our work routinely references SANS 10400-H, municipal stormwater and flood line policies, SANRAL drainage guidance where applicable, and DWS flood line and water-use processes — always tied to the specific site, catchment, and receiving environment you are working in.
Where we work
We support projects nationwide and prepare location-specific briefs for major centres. Each city hub links to every consulting discipline we offer, with introductory context for that region's climate, topography, and typical authority questions.
