Water Scarcity

Mims Davies Excerpts

Tuesday 9th December 2025 Westminster Hall

[Robbie Moore]

As the hon. Member will know, it is down to the regulator to set how much a water company is able to spend on infrastructure projects. Ofwat has not provided water companies with the flexibility they need to provide the correct level of investment. There is significant frustration about that, and that is coupled with frustrations about our planning system that have prevented large water storage schemes from progressing through the system. It is really disappointing that this Labour Government’s Planning and Infrastructure Bill, which is progressing through the House, does not address any of the issues associated with the challenges of increasing water storage and water resilience in this country. That is a real missed opportunity by this Labour Government.

We all know that the last Government took some steps to address the risks of water scarcity. We set a clear direction through the Environment Act 2021 to reduce water consumption by 20% per person by 2038. Although the target will ease demand, we should still be planning to address the larger challenges around increasing water storage. I was proud to help develop the last Government’s plan for water, which set clear objectives to improve efficiency, reduce leaks and plan for increased supply. It is encouraging to see that the Government have announced a further 670 million litres of daily water supply through the proposed new reservoirs, but I challenge the Government on the speed of delivering them, including the Fens reservoir, as mentioned by the hon. Member for South Cambridgeshire (Pippa Heylings). It is frustrating that the Planning and Infrastructure Bill—a key piece of legislation—has not addressed those challenges on the speed of delivery.

Weir Wood and Ardingly reservoirs in my constituency are covered by South East Water, which, out of the blue, wants to build an overland emergency pipe to improve water resilience, but there has been no consultation or engagement with businesses and residents even though the pipe will affect 58 residences and homeowners, as well as the Bluebell railway line. Does my hon. Friend agree that part of the issue is a lack of consultation?

[Robbie Moore]

Yes—absolutely. My hon. Friend has spoken to me on many occasions about her challenges with South East Water, which is not investing sufficiently in increasing water storage capacity. I know there is a meeting tonight to address some of those challenges, but South East Water seems to be consistently chasing its tail and not interacting enough with my hon. Friend, in whose constituency these reservoirs are, or with wider water users. More openness and transparency should be expected from South East Water.

Although new reservoirs are definitely needed—I think all Members in this Chamber would concur on that—we must have a broader conversation about water in this country, and most importantly, how we value water. Water can have a positive or negative value depending on whether one’s constituents are being flooded or whether one’s area needs to store more water. At the moment, we are wholly reliant on water companies to deliver major infrastructure and reservoir projects. When a price review index is set by a regulator in a five-year rolling strategy, it is not providing the flexibility that the Government require to increase water storage.

I encourage the Government to go further to provide more certainty on increased water storage beyond that which has already been announced. Would it not be better to look at how we can deliver greater water storage capacity in a dispersed way? We should empower smaller-scale projects on private land, which could involve incentivising farmers or landowners, potentially financially, to not only go above and beyond the water storage capacity they need for their own usage, but to store water on their land and then release it to a water grid. I encourage the Government to look at different ways of attracting private sector investment to increase water storage capacity, rather than it being the water company’s responsibility to do that. We must think outside the box on this water resilience issue.

Likewise, farmers and landowners do a great service when they allow their land to be flooded during rainy periods. I remember very well, having previously been the water Minister, that I met many farmers who had been flooded during Storm Henk and Storm Babet. Environment Agency assets had burst, and the Environment Agency was saying to me—the current Minister may be getting the same response—that we must not look at dredging or removing vegetation from our man-made assets to get water to flow better through the system. If she is getting that advice, as I did, I would encourage her to push back and say that, as well as trying to build better flood alleviation schemes, we should look at those strategies for water to be stored to potentially deal with some of our water scarcity issues we have.

Vast amounts of water are there for us all to see when the land is flooded, and there is an opportunity to use that land to deal with water scarcity issues. At the moment, far too much water is going out to sea during rainy periods and then, come summer, as we have all experienced with another drought, we cannot deal with the water resilience issues.

Finally, I strongly encourage the Minister to look at how we can expand and develop the relationship and the flexibility between the internal drainage boards, the Environment Agency, and landowners and farmers who want to increase water storage and capacity on their farm but also want to move water through the system. The catchment-based approach of IDBs and their grassroots nature mean they are doing some excellent work across the country. While they are facing challenges, the way that they are moving water across our farmland and farm businesses is a huge success story.

I hope the Minister will be able to tell us what level of investment the Government are making beyond the current promises about existing reservoirs that have been announced. How will the Minister deal with the planning challenges to ensure that we get more smaller-scale reservoirs built at speed? What future legislation is she planning to present to the House beyond the missed opportunity of the Planning and Infrastructure Bill, which does not deal with water resilience or security measures? What additional pressures are the Government putting on water companies like Yorkshire Water to deal with water leakage, despite us seeing hose pipe bans and dealing with challenges around water security? We have heard South East Water, Yorkshire Water, Southern Water and Thames Water all mentioned in this debate, but we do not have certainty from the Government that they are putting enough pressure on those providers.
