I took a water company to court over sewage pollution. Here’s why I’m still campaigning.
My name is Jo Bateman, and I am taking legal action against South West Water because I am sick of sewage pollution ruining the sea where I swim.
A few years ago, I was living in the Midlands, about as far from the coast as you can get. I loved walking, so I decided to spend a week on the South West Coast Path, from Poole to Lyme Regis. That week changed everything. I fell in love with the sea. Not long after, I handed in my notice, sold my house, and moved to Exmouth to live by the coast.
Then one winter’s day, I was persuaded to get into the sea, reluctantly at first. From that moment, I was hooked. I have been sea swimming year-round ever since. When I am in the water, everything going on in my head gets left behind on the shore. All that exists is me, the sea, and the cold. When I get out, I feel completely transformed. The mental health benefits are huge. It reduces stress, lifts my mood, and gives me a sense of calm I cannot find anywhere else.

From sea swimming to sewage pollution awareness
At the beginning, I knew nothing about sewage pollution, and ignorance really was bliss. I could enjoy the sea without thinking about what might be in it. But over time, that changed. I started seeing alerts warning of sewage discharges into the water. There were days when the sea was unsafe, days when I could not swim, and days when something that had become essential to my wellbeing was taken away from me.
The more I learned about sewage dumping by water companies, the more shocked and angry I became. It was not just occasional incidents. It was frequent, systemic, and deeply damaging. What had started as a personal passion quickly became a source of frustration and concern. Eventually, I reached a point where I felt I could not just stand by and accept it.

Why I took legal action against a water company
In 2024, I decided to take South West Water to court. I filed a claim in the small claims court, seeking compensation for loss of amenity because repeated sewage pollution was preventing me from swimming. The cost to file the claim was £50, and I asked for £379.50 in compensation.
But this was never really about the money. It was about the principle. Why should water companies be allowed to pollute our rivers and seas and face so few consequences?
Water companies often argue that sewage discharges are unavoidable, particularly during heavy rainfall. They say the system cannot cope and that dumping sewage is necessary to prevent worse outcomes. I do not accept that explanation. Rain is not new. The UK has always experienced heavy rainfall. The real issue is decades of underinvestment in infrastructure, combined with a system that has prioritised shareholder payouts over environmental protection.

From one legal claim to a growing movement
What happened next was something I never expected. My case resonated with people far beyond Exmouth. What started as a small claim quickly grew into something much larger.
The case is now supported by the law firm Leigh Day and has progressed to the High Court. Alongside this, a group legal action has been launched on behalf of the people of Exmouth, with more than 1,300 claimants taking action against South West Water.
Personally, my life has changed beyond recognition. I have become part of a wider community of people who care deeply about clean water and are willing to speak out and take action. I have gone from being a relatively quiet person to speaking in Parliament, appearing in national media, and addressing large crowds at protests and events. There is even a documentary telling my story (find out more).

Why I am still taking on water companies
Taking on a water company can feel like a David and Goliath battle. These are large, powerful organisations with significant resources. I am just one individual. But I believe this fight is necessary.
Clean water should not be a privilege. It should be a basic right. We should be able to swim in the sea without worrying about sewage pollution. We should be able to trust that water companies are protecting the environment, not harming it.
We live in a world where extraordinary technological achievements are possible. It should not be beyond us to build and maintain a sewage system that does not pollute our rivers and seas. Real change requires accountability. It requires proper enforcement of environmental laws, and it requires water companies to stop putting profit before pollution.

A message to others fighting sewage pollution
If there is one thing I have learned through this experience, it is that individual action matters. You do not have to accept the status quo, and you do not have to stay silent.
There are thousands of people who feel the same way, and together we are far more powerful than we are alone. Collective action can drive change, even in the face of powerful institutions.
This is about all of us. It is about the future of our rivers, our seas, and our environment. And it is a fight we cannot afford to lose.
Because nature needs us.
