Water Sector: Public Ownership

Peter Prinsley Excerpts

Monday 14th September 2026 Westminster Hall

[Dr Peter Prinsley (Bury St Edmunds and Stowmarket) (Lab)]

It is a pleasure to serve under your chairship, Mrs Barker. I thank my hon. Friend the Member for Colne Valley (Paul Davies) for securing this debate.

What should be at the centre of a discussion about public ownership of water? I think it should be public health. Imagine a family spending an afternoon beside a river. The children are playing near the bank. One asks whether they can paddle. The parent looks at the water and hesitates. Hon. Members might think it is because the river is deep or flowing quickly, and they might be right, but just as importantly, the parent does not know what has been discharged into it. That should concern every one of us.

In Bury St Edmunds and Stowmarket, the rivers connect our towns and surrounding villages. They should be places that communities enjoy and take pride in, not places from which parents feel they must warn their children away. Yet when we discuss the water and sewerage companies, the conversation too often begins with the company finances and ends with arguments about regulators. I think we should begin with the family beside the river.

Julie is the mother of Heather, who was just eight when she died in 1999 after contracting E. coli during a family holiday in Devon. Her family story featured in the Channel 4 drama that we have heard about. Julie continues to speak out, so that Heather is not forgotten and so that other families understand the risks, but behind that campaigning is a mother who should have been watching her daughter grow up. That is why I believe the case for public ownership of our water and sewerage companies must be made in terms of the people this essential service exists to protect.

The purpose of the water system should be straightforward: to provide clean, safe water. We need water and sewerage companies that have more actual engineers than financial engineers. Our constituents should not have to become experts in the sewage discharge maps before deciding whether to enjoy their local river. No parent should be left wondering whether an ordinary afternoon outdoors puts their child’s health at risk. We cannot promise that open water will ever be entirely risk-free, but we can insist that preventable pollution be treated with the seriousness it deserves. Water is essential to life, and the way we own and manage it must reflect that.
