Water Resources Engineer

What Does a Water Resources Engineer Do?

Water resources engineers design, build, and manage the infrastructure that supplies clean water, treats wastewater, controls flooding, and protects aquatic ecosystems. As climate change intensifies droughts in southern Europe and increases flood risk in the north, these engineers are more critical than ever.

The role combines hydrology, hydraulics, environmental science, and civil engineering. Projects range from urban stormwater management and water treatment plant design to large-scale dam safety assessments and river restoration. Increasingly, water resources engineers also work on nature-based solutions - constructed wetlands, permeable pavements, and green roofs - that deliver both engineering performance and ecological benefits.

In Europe, salaries range from €40,000 to €70,000 in countries like Germany and the Netherlands, with senior roles in Switzerland exceeding CHF 120,000. The EU Water Framework Directive and the European Floods Directive continue to drive demand for qualified professionals, particularly those skilled in hydraulic modelling and climate adaptation.

Key Responsibilities

• Design water supply, wastewater treatment, and stormwater management systems
• Perform hydrological and hydraulic modelling (HEC-RAS, MIKE, SWMM)
• Assess flood risk and develop climate adaptation strategies
• Ensure compliance with the EU Water Framework Directive and local regulations
• Manage water quality monitoring programmes and environmental impact assessments
• Design nature-based solutions such as constructed wetlands and sustainable drainage

Required Education

• Bachelor’s or Master’s in Civil Engineering, Environmental Engineering, or Hydrology
• Experience with hydraulic modelling software (HEC-RAS, MIKE, InfoWorks)
• Knowledge of the EU Water Framework Directive and Floods Directive
• Understanding of water quality chemistry and treatment processes
