A day in the life – Wastewater treatment operator
What it's like
Water and wastewater engineers make sure our water is clean and safe! You'll manage the process of bringing untreated water from rivers or groundwater into treatment plants.
You’ll help design and construct structures that manage water, such as sea walls, pumping stations and reservoirs. Maintaining these systems is also part of your role. By creating energy-efficient systems that reduce greenhouse gas emissions, you’ll help fight climate change.
Water and wastewater engineers work in local councils, private engineering firms, environmental consultancies and utility companies. You could specialise in flood risk management, industrial water treatment or sustainable drainage systems.
Your tasks might include:
designing water treatment and sewage systems for new developments
inspecting existing infrastructure to spot leaks or inefficiencies
modelling water flow using specialist software
advising on ways to reduce water pollution
preparing technical reports for clients or regulators
overseeing construction projects to make sure standards are met
