• Contributing to the technical design and assurance of the storm overflow programme – providing input, options, challenge, steer and governance to ensure we design & deliver a technically feasible set of interventions for our AMP8 programme.
• Undertaking the technical assurance of benefits from the storm overflow programme – designing monitoring programmes, conducting modelling & analysis to ensure we measure the benefits of the interventions and justify our PR24 assumption base to secure circa £2 billion investment.
