Storm overflows are very provocative and not acceptable to our customers and stakeholders. We want to lead the charge in resolving the current situation. That’s where our Clean Rivers & Seas Task Force comes in, implementing pioneering and industry-leading solutions to reduce spills and reliance on overflows whilst also enhancing the environment for our communities. Currently delivering a £1.5billion programme over the next 10 years, and we are now expanding the team so we can continue to work in partnership to deliver a larger programme of sustainable and innovative interventions to reduce the use of storm overflows.
We have a range of brand-new Wastewater Network Specialist roles available (from Principal to Specialist) created to join our Clean Rivers & Seas Task Force.
About The Role
A critical technical role in the clean rivers and seas task force which ensures we have a technically creditable programme of works that delivers the spills reduction, where we need it, at the right pace.
What You Will Be Responsible For
- The role will involve analysing wastewater catchment performance, modelling scenarios, proposing and reviewing technical solutions and monitoring performance.
- You will contribute to the technical design and assurance of the storm overflow programme – provide input, options, challenge, steer and governance to ensure we design & deliver a technically feasible set of interventions for our AMP8 programme.
- You will undertake the technical assurance of benefits from the storm overflow programme – design monitoring programmes, conduct modelling & analysis to ensure we measure the benefits of the interventions and justify our PR24 assumption base to secure circa £2billon investment.
- You will support innovative approaches for analysis with our Technical Lead and other thought leaders internally, in academia, across the UK water industry and the supply chain.
