The Parliamentary Debate About the “Performance of South West Water”

On March 5th a debate was held in the Grand Committee Room next to Westminster Hall concerning the “Performance of South West Water”.

You can read the transcript of the entire session in Hansard if so desired. Alternatively you can watch a recording of the entire session.

The debate was opened by Simon Jupp MP as follows:

I beg to move,

That this House has considered the performance of South West Water.

It is a pleasure to serve under your chairship, Mr Henderson. I am delighted to have secured this important debate, one year on from another debate that I secured on the performance of South West Water. It is another opportunity to hold South West Water to the highest possible standards in the House.

Last year, I described the performance of our water company and its historic lack of investment as “shameful”, and many of my constituents shared my point of view. This year, I want to focus my speech on the facts facing my constituency of East Devon. The public want to see evidence of improvement and delivery of the promised investment, and they want South West Water to clean up its act and our water. South West Water must deliver better services for our constituents, improve our bathing waters, and protect our natural environment. Not doing so puts the vibrancy of our coastal communities under threat.

More on all that later. However, we’re going to start our discussion with the speech given by the Member of Parliament for North Devon, Selaine Saxby. Here is a recording of her presentation:

Ms. Saxby’s opening remarks were as follows:

March Sewage Pollution in South West England

It’s the day after February 28th, and the previous month’s sewage pollution article is overflowing with almost continuous news of combined sewer overflow activations around the coast of Devon and Cornwall. I’ve taken the liberty of starting this article a day early, hoping rather than expecting that March will be a bit quieter.

After yet more rain overnight, here is this morning’s Surfers Against Sewage map of pollution around our coasts:

Starting with the local surfing beaches, sewage pollution has been occurring this morning at Widemouth Bay:

and the adjacent Trevone and Harlyn Bays, amongst numerous other places across Cornwall:

A Critical Review of Bathing Water Quality Forecasts

A press release by the University of Reading earlier this week claims that:

The UK’s bathing water forecasts need urgent improvement to prevent beach goers from swimming in sewage without warning.

The University is publicising a review paper in the journal WIREs Water entitled “Forecasting bathing water quality in the UK: A critical review” that was first submitted in December 2022. According to the press release:

With increasing attention on UK water companies and others to clean up rivers and beaches, the review, published in WIREs Water, suggests current bathing water forecast models are not keeping the public safe at most of the UK’s 600-plus designated bathing water locations.  

The current outdated methods cannot accurately predict threats from pollution caused by sudden downpours, the scientists say. Heavy rain can lead to sewage overflows or agricultural run-off. In addition, a lack of water quality sampling and outdated forecast methods leave people vulnerable to sudden increases in chemicals or bacteria in the water.

With coastal and wild swimming becoming more popular, local authorities urgently need to make use of improved forecasting techniques to identify the dangers from bugs such as E. coli or intestinal enterococci, which can be lethal, the researchers said.

According to lead author Karolina Krupska:

We expect beaches that are designated for swimming to be clean and safe, but authorities often don’t have good enough information to issue warnings, leaving swimmers and surfers more vulnerable to getting ill. The way we manage our sewage and land means rivers and seas are frequently polluted, and heavier summer downpours due to climate change is making the problem worse at the time of year when people are most likely to be at the beach.

With existing pollution warning systems, beach users don’t have good enough information to decide whether it is safe to go in the water. The science underpinning the next generation of bathing forecasting already exists, but a lack of action means these solutions have not been implemented.

We need a more reliable and frequently updated early warning system, to ensure people can safely enjoy a coastal swim with the confidence that they aren’t putting themselves at risk.
