It is a pleasure to serve under your chairmanship, Mr Pritchard. I congratulate my hon. Friend the Member for Westmorland and Lonsdale (Tim Farron) on securing this critically important debate. In my Oxfordshire constituency of Didcot and Wantage, over 90% of water infrastructure is managed by Thames Water—a de facto monopoly. The constituency impacts of the current arrangements are stark. In south Oxfordshire, sewage from storm overflows into water bodies exceeded 11,000 hours in 2023 during 810 spills. Recently, in East Hanney and Didcot, overwhelmed sewage pumps have led to flooding, including with contaminated water. Thames Water was the worst performer in the country for leaks, leaking 570.4 megalitres a day last year, or more than 200 billion litres in total, equivalent to just under a quarter of its entire water supply. Analysts estimate that Thames Water’s current debt amounts to about 80% of the value of its business, making it the most heavily indebted of the water companies in England and Wales. At the same time, Thames Water has said that its bills need to rise by 59% between 2025 and 2030 or it will not be able to recover from its financial crisis. It is in that context that proposals for a reservoir in my constituency are causing concern to local residents. Even putting to one side the fact that many are sceptical of the case for the reservoir, there is concern about whether Thames Water can be trusted to competently programme, manage and deliver what would be the second largest reservoir in the country and one of the largest civil engineering projects in the land.
