Wastewater Treatment and Asset Management team

We’re helping to clean up the nation’s rivers. We’re enhancing the environment for everyone. We’re part of a critical industry for our society. This is your chance to join us and help to change our world for the better – in a big way.


We’re focused on doing the right thing.

We provide our communities with the fresh water that they need to keep life flowing. But just as crucially, our Wastewater Treatment team treat and recycle 700 million litres of wastewater at our 368 treatment works every single day. To maintain this vital cycle, we make water safe enough to be returned to rivers, the sea and ultimately, people’s homes.

Our Asset Management team boost the resilience of our network to reduce pollution and leakages – and increase the reliability of this vital service.

There’s huge scope to make a difference here. If you have strong ideas and the talent to see them through, you’ll enjoy autonomy and support every step of the way. You’ll get to develop and flex your skills in an organisation that offers the scale to make a lasting impact. We want analytical problem solvers who are up for a challenge – people who care about improving the environment and keeping water flowing for millions of people. 

It’s a collaborative effort, working with teams across four key areas:

  • Asset Management Transformation & Business Analytics
  • Risk and Resilience
  • IT Systems, Insights and Data Analytics
  • Civil, Electrical and Mechanical Asset Engineering.
