If you're confident managing risk, forecasting with precision, and balancing commercial priorities while delivering to time, cost and quality, you’ll feel right at home in this role. As you will be required to travel to sites 2 day per week, a full, UK Driving Licence & access to a vehicle is essential. Southern Water is at the forefront of transforming Britain’s water industry, investing significantly to enhance resilience, sustainability, and service excellence.
