Independent Water Commission: Final Report

Roz Savage Excerpts

Tuesday 10th February 2026 Westminster Hall

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

It is a pleasure to serve under your chairship, Sir Jeremy. I thank my hon. Friend the Member for West Dorset (Edward Morello) for introducing this important debate—I have to say, it feels like the nth debate that we have had on this issue. I am getting a very strong sense of déjà vu from standing here and in the Chamber and speaking about water. Sadly, I suspect I will stand here and speak on this subject many more times over the coming years.

I know the Minister is passionate about this subject. There are some aspects of the White Paper that I welcome, but I feel that it does not go far enough. I will come on to specifics in a moment, but right now I want to share a mental image. In my constituency, at least 16 sewage outflows are spewing sewage into our rivers—just picture that. With the current stuck weather system and more rain expected, that is set to continue. I find that really distressing and I am sure that everybody here does too.

The central problem is that the water system is now built around profit. The privatised model has failed. That is a serious market failure, and it needs to be remedied. I am not here to defend Margaret Thatcher’s vision—far from it—which was that we would go from being a nation of shopkeepers to a country of shareholders. The somewhat foreseeable consequence of that was that people—individuals and private share owners—would sell their shares, and so we have ended up with big institutions owning our water companies and exploiting them as vehicles purely for profit. That profit motive does not sit well with a vital public utility.

I will point out four recurring failures in the Government’s approach, on this issue and possibly on others: they lack the courage to truly grasp the nettle on failing systems; they are overlooking nature-based solutions, despite strong evidence that they work; they are misunderstanding farming, as the hon. Member for North Herefordshire (Dr Chowns) referenced, and ignoring the dual role that farmers play as part of the problem and as a big part of the solution; and they are failing to unleash people power.

Nature-based solutions are still being treated as an afterthought, despite evidence that constructed wetlands can remove 60% to 90% of nitrates and phosphates. Nature can be a great ally in this, and there is no downside to using nature-based solutions. The approach on agriculture is piecemeal and inadequate. Agriculture accounts for about 40% of water pollution in English rivers, but the proposed action is seriously underpowered. We need environmental land management funding to be better targeted at water outcomes, and we need to include farmers to unleash what they know about their land. To restore faith in the water industry we need transparency and accountability. We could unleash the power of citizen science to monitor water, as residents are the people most motivated to track water quality.

Finally, I return to the fundamental issue of water company ownership. The Liberal Democrats are calling for Thames Water to be converted into a public benefit company, or possibly a mutual company owned by its customers. Changing ownership of Thames Water is the only way to solve this problem for the long term. I thank the Government for where they have gone, but I beg them to go so much further.
