Water Scarcity

Chris Hinchliff Excerpts

Tuesday 9th December 2025 Westminster Hall

[Chris Hinchliff (North East Hertfordshire) (Lab)]

It is an honour to serve with you in the Chair, Mr Stuart. I begin by recognising that the Minister takes these issues very seriously, and congratulating the hon. Member for Horsham (John Milne) on securing this important debate. I agree with him that one would think it would take true organising genius to arrange for water scarcity in a country as wet as ours. Yet water scarcity is not a future risk; it is a constant and present reality. Take chalk streams, which have already been referred to: they are the crown jewels in our natural heritage, but less than a fifth are in good ecological status, and that situation is largely driven by over-abstraction.

The River Ivel in my constituency is one of the most over-abstracted chalk streams in the country. Where once there were boats, watermills and watercress meadows, there is now often little more than a dribble. The nearby Cat Ditch chalk stream mostly no longer flows at all. If we are to deliver on our manifesto commitments to reverse England’s nature crisis, we must ensure that we have a chalk streams-first approach to water resource management, adopted in full.

The second point I will make is that reservoirs alone will not save us. The planned nine new reservoirs up to 2050 will provide around 670 million litres of water a day but, as has already been referred to, our projected deficit is more than 5 billion litres a day. The calculations for existing water resource management plans do not take into account the quenchless thirst of data centres, demanded not by our constituents, but by tech corporations.

The brings me to my third point: we must move towards an economic model and a planning system that respect environmental boundaries and stop acting as though they do not exist. Speculative applications from profiteering developers must be reined in and firmer restrictions put in place where new development would require abstraction at rates not compatible with the good ecological health of our rivers. We must also make more efficient use of grey water. Above all, we need a clear national assessment of the maximum population growth we can absorb in our country, for a future in which both our taps and our rivers still run.

At the moment, the chief executive needs to focus on getting the boil water notice removed and getting drinking water back into everybody’s house. Of course, the Drinking Water Inspectorate will be doing a full investigation into exactly what has caused the problem and why it has taken so long to resolve. South East Water is responsible for compensating customers. The changes that we introduced to the guaranteed standards scheme mean that for the first time compensation can be given to people who are under boil notices. Under the previous Government someone under a boil notice did not receive any compensation; we have introduced compensation. Customers will be compensated not only for not having water but for the duration of their boil water notice.

On water scarcity, I agree with many of the points that have been raised. My hon. Friend the Member for North East Hertfordshire (Chris Hinchliff) talked about the over-abstraction of chalk streams and he is absolutely right that that is crucial. Over-abstraction and pollution are the main causes of problems for our chalk streams. One of the reasons that we have such a demand for future water is because we are committed to reducing abstraction, particularly from our chalk streams. He is right to say that we cannot think just about having the reservoirs; we need more actions, including strong and stringent targets to reduce leakage, and we need to look at all our water needs going forward. He was right to highlight—although there seemed to be some amnesia in the Chamber—the years of under-investment in water and in infrastructure more widely. We are getting on with doing many things that should have been done in the last 14 years.

Briefly, may I encourage the Minister to come to my constituency and see the incredible work being done by the RevIvel campaign, which is trying to restore the Ivel chalk stream? It has a brilliant proposal for a chalk stream-first approach that would restore not just that chalk stream but the whole chalk aquifer and help the Cat Ditch flow again. It would be great to see her there.

I thank my hon. Friend for that lovely invite. Visiting a chalk stream sounds beautiful—perhaps in springtime, when it is looking particularly gorgeous, or in summer.

I agree with so many of the points made—even those made by the shadow Minister—about farming, what we can do to support farmers and how we can make it easier for them to store water on their land. At this moment, I cannot commit to saying exactly where my thinking is on this, but I can say I am looking at it extremely closely: how can we make it easier for farms to become more resilient and for farmers to store water when it rains, so that it is there when they need it? I have also been looking closely at the interestingly titled WAGs—I thought that meant something else entirely, but as we all know stands it for water abstraction groups. I have been looking at how they have been doing some of that work.
