Water Sector: Public Ownership

Debate between Caroline Voaden and Roz Savage

Monday 14th September 2026 Westminster Hall

[Dr Roz Savage (South Cotswolds) (LD)]

It is a pleasure to serve under your chairmanship, Sir Jeremy. I am grateful to the hon. Member for Colne Valley (Paul Davies) for opening this debate and for his patient and gracious fielding of so many interventions. I express my thanks to Ash Smith and the phenomenal team at Windrush Against Sewage Pollution for bringing this petition before Parliament and for their dedication and commitment to protecting our rivers. I also thank the other campaigners who are in the Gallery; they are passionate and perseverant in their pursuit of cleaner water across our country.

More than 208,000 people signed the petition, including over 600 of my South Cotswolds constituents, which is the ninth most sewage-polluted constituency in the country. Last Saturday, I stood beside the River Coln at Fairford in my constituency with residents who are sick and tired of seeing their river used as a sewer. I spoke with Debbie Campbell, who is in the Gallery and who was most charmingly dressed as a poo emoji. Debbie became a campaigner after swallowing polluted water while open water swimming and ending up doubled over in pain. Her experience is shocking, but sadly the pollution that caused it is no longer exceptional; it has become the norm.

Behind the sewage scandal lies another scandal—what has happened to customers’ money? The promise of privatisation was that private capital would bring investments and efficiency, but research from the University of Greenwich estimates that between 1991 and 2023, shareholders extracted around £85 billion more from English water and sewerage companies than they actually contributed in new equity.

[Caroline Voaden (South Devon) (LD)]

The sewage literally flows outside the King of Prussia in Kingsbridge, and customers have to be really careful when they step outside it every time we have heavy rain. Does my hon. Friend agree with me and the more than 800 people who signed the petition from my constituency that we have to look again at the water ownership model? It is just not working: bills are going up and up, while shareholders are still extracting money from the water companies rather than it going into upgrading infrastructure.

[Dr Savage]

I absolutely agree that we need to get upstream of the problem, and I assure her that I always try to step out of pubs carefully.

The supposed justification for private ownership was that investors would bring money into our water system. Instead, over those three decades, vastly more money has flowed out to shareholders than shareholders put in. Money went out, infrastructure deteriorated and debt piled up, and now customers are being told that they must pay to put it right. That is what makes the British public and me so furious. The water companies need to come clean and so does the Government.
