Bathing Water Regulations

Debate between Pippa Heylings and Rachel Gilmour

Tuesday 4th March 2025 Westminster Hall

[Pippa Heylings (South Cambridgeshire) (LD)]

It is an honour to serve under your chairship, Sir John. I thank my hon. Friend the hon. Member for Taunton and Wellington (Gideon Amos) for securing this critical debate.

While covid-19 undoubtably brought on many challenges, one positive outcome was the surge in open-water swimming. More people than ever before enjoyed blue spaces for recreational activities, reaping significant benefits for both their physical and mental wellbeing. However, many were more cautious about diving into freezing cold lakes, rivers and streams when they were aware of the level of bacteria and pollution present in our waters. As Liberal Democrats, we have long and passionately campaigned on this issue. Last year, the Lib Dems discovered that water companies had discharged sewage over 100,000 times in areas designated as current bathing waters, putting public health and local ecosystems at risk.

[Rachel Gilmour (Tiverton and Minehead) (LD)]

My constituency of Tiverton and Minehead neighbours the patch of my hon. Friend the Member for Taunton and Wellington (Gideon Amos). Very recently, one of my constituents shared a harrowing story with me, in which his children fell seriously ill after swimming in a local river last summer. These public health risks are further exacerbated by bad flooding in our areas, as we have seen in recent episodes, which sweeps contaminants and overwhelms sewage systems into our waterways, degrading water quality. Does my hon. Friend agree that stricter regulations must be introduced in the interest of public health and to ensure that our bathing waters are safe for everybody to enjoy?

[Pippa Heylings]

I completely agree. I emphasise what my hon. Friend the Member for Taunton and Wellington said: that is why we need tougher action on the water companies. We also need to take action on combined sewers and make improvements to the small sewage treatment works on many chalk streams, like in my constituency. However, today’s debate is about bathing site designation, which is one of the effective levers that can be used.

We are talking about the proposed reforms by the Department for Environment, Food and Rural Affairs to bathing site designations. I would like to talk about the second core reform being proposed, which I am concerned would lead to a real reduction in the number of bathing sites being designated, rather than the increase that we should see, particularly for inland waters. The second core reform says that we should

“Include the feasibility of improving a site’s water quality to at least ‘sufficient’ as a criterion for final designation. This would avoid poor value for money, by limiting expenditure where water quality improvement is not feasible or proportionate.”

To best demonstrate why that reform would not only fail but could also damage water quality in our rivers, it is worth sharing the story of Sheep’s Green in my constituency. For centuries, people have been enjoying Sheep’s Green—a popular spot on the River Cam. It was at Sheep’s Green that we worked to bring in a bathing site designation, because of the poor quality of the water.

In October 2023, the Cam Valley Forum, a local voluntary organisation, submitted an application to DEFRA to grant Sheep’s Green designated bathing water status. That came after three years of hard work by local volunteers, which is truly commendable, and was based on the success of the River Wharfe. Sheep’s Green had been used for decades without official recognition, and the idea of getting it designated bathing status had widespread public support. Over the course of a 10-week consultation, the Cam Valley Forum received more than 500 responses, with an overwhelming 93% in favour of the designation. South Cambridgeshire district council and Cambridge city council also formally backed the proposal. Anglian Water, with whom I worked, also fully supported the designation application.

Once designated, as predicted by local volunteers and citizen scientists, Sheep’s Green was classified as having poor water quality. That triggered a statutory obligation for improvements to clean up the source of the pollution—the Haslingfield sewage works in my constituency. For years, local citizen scientists had suspected it was the culprit. Now, finally, Anglian Water was legally required to act.

Bathing water status also unlocked funding from Ofwat under the water industry national environment programme. Tens of millions of pounds vital for the infrastructure improvements needed to reduce the sewage discharges were made available for Haslingfield, with work expected to begin in the next two years. These improvements will not just benefit swimmers at Sheep’s Green, but have a wider impact on the ecological health of the River Cam.

However, had core reform 2 been in place when the Cam Valley Forum began its journey in 2020, there would have been no bathing water designation for Sheep’s Green. Without that designation, there would have been no investigation by the Environment Agency, no identification of Haslingfield sewage works as the source of the pollution and no legal requirement for Anglian Water to take action. The WINEP funding would not have been available and we would have lost the opportunity for water improvements and nature restoration in South Cambridgeshire.

In short, core reform 2 would have inadvertently blocked the clean-up of hundreds of rivers. Local organisations like the Cam Valley Forum are not just highlighting a problem with their concerns around core reform 2—they are demanding action. They are rightly pushing for bathing water status because it is a vital tool for driving cleaner, healthier rivers. We should be supporting these efforts, not hindering them.
