About water & flood risk jobs in the UK
The water and flood risk category covers a wide technical field: hydrologists and hydrogeologists modelling surface and groundwater systems; flood risk consultants preparing Flood Risk Assessments (FRAs) and Sustainable Drainage System (SuDS) strategies for planning applications; water resources planners at water companies working on WRMP24-aligned supply-demand balances; and Environment Agency officers regulating abstractions, discharges and flood defence programmes.
Water company employers include the ten regional undertakers (Thames Water, Severn Trent, United Utilities, Anglian Water, Yorkshire Water, Wessex Water, Southern Water, South West Water, Northumbrian Water, Welsh Water). Their AMP8 investment programme (2025–2030) is driving significant hiring across environmental compliance, catchment management and net zero delivery.
In consultancy, teams sit inside major multidisciplinary firms (WSP, Arup, Stantec, Wood, Mott MacDonald, JBA Consulting, RSK) alongside specialist flood risk consultancies. Regular workstreams include hydraulic modelling (Flood Modeller, HEC-RAS, InfoWorks ICM), catchment-based flood management, and Water Framework Directive assessments.
Related categories: Environmental Consultancy, Planning, Climate (climate adaptation and physical risk overlap significantly), and Waste and Recycling.

Thames Water, Severn Trent and United Utilities are the largest by headcount. All are actively hiring against AMP8 (2025–2030) commitments.
