Given that the 2035 and 2050 targets have been criticised for lacking sufficient ambition and urgency, will the Minister consider allowing Ofwat to permit sewage companies to deliver their improvement plans earlier and to higher standards? Southern Water, in the area I represent, aims to meet the storm overflow targets, but it would hit 80% by 2030, rather than 75% by 2035, which is the Government’s target.

I will get straight to the point. For the record, this Government did not vote to allow raw sewage to be discharged into rivers. On the contrary, it was this Government, through a whole range of processes—in particular, six pages of clauses in the Environment Act 2021, which I was proud to bring through with the support of many hon. Members here—who put in place a comprehensive system for dealing with our sewage once and for all. We also set targets to reduce storm sewage overflows via the storm overflows discharge reduction plan, announced by the other former Minister, my hon. Friend the Member for St Austell and Newquay (Steve Double). We hope the current Minister—I welcome her to her place—will make sure we keep to the targets. In 2025, the Government have to report on progress. I agree with my hon. Friend the Member for Bexhill and Battle (Huw Merriman): I think we can bring forward the 2050 target and get rid of the impact of these overflows quicker.

We have heard talk about elimination of storm overflows altogether and about a 2050 target. All the water companies are saying that they can do it. I do not think that is a realistic proposition. To eliminate CSOs altogether, we would need to completely separate surface water from the combined sewers. That means disconnecting all the road drains that are connected. It means disconnecting roof drainage. Hon. Members have suggested butts to deal with that, but they would still have to be disconnected from the sewers. Private surface water connections would also have to be identified because people drain their driveways or gardens and connect them into their own combined drain. All that needs to be identified and eliminated, so I would urge the Minister to think carefully about the practicalities of what is required. We would need massive new surface water sewers and pumping stations and, as I say, there would be disruption in many roads and streets throughout the country.

There has been some talk about the Environment Agency being resourced to be able to carry out that role. DEFRA and its agencies received £4.3 billion in the 2021 spending review to do more to tackle climate change and protect our environment for future generations. In terms of the response to Ofwat, Ofwat’s investigations will consider how overall companies operate, manage their sewage treatment works and report on their performance where the investigations can find failings on obligations. Ofwat is responsible for enforcing; it will use its full range of powers accordingly to hold companies to account for their failures, and to require them to put things right in short order.
