South East Water: Disruption of Supply

Chris Hinchliff Excerpts

Wednesday 3rd June 2026 Commons Chamber

[Emma Hardy]

I thank the hon. Lady for her work on the EFRA Committee. She is entirely right: it is unacceptable. I feel that I am a fair-minded person. I know that water companies cannot control the weather, and I know that they cannot build a reservoir overnight. However, they certainly can contact their Members of Parliament, contact their councils, get in touch with their local resilience forums and make sure that they communicate with their customers, as an absolute bare minimum, and that is exactly the conversation that I will be having with each and every one of them.

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

Alongside the failures in the south-east, during the recent heatwave there was a widespread disruption of water supply across swathes of my constituency, in Buntingford, Cottered, Ardeley and Throcking. In a country as wet as ours it should take a true organising genius to create disruptions in water supply, but we are on track for a water deficit of 6 billion litres in our country in the coming decades, and on top of that, AI data centres estimate that water consumption will reach up to half a trillion cubic metres every year. Does the Minister—whom I deeply respect—accept that if we are to prevent water supply disruptions from recurring year in year out, we cannot continue to have infinite increases in demand on our already vastly overstretched water resources?

[Emma Hardy]

My hon. Friend is right. It is astonishing that although, owing to climate change, we will experience wetter and wetter winters and drier and drier summers, we have no capacity to store water in the winter and use it in the summer. That seems to me to be absolute nonsense.

As for the issue of data centres, there is one possibility that I am keen to look into, and I touched on it in an earlier answer. Under the current legislation, water that is supplied by a water company must be of drinking-water standard. It strikes me as logical and sensible to say, “If water is being used for cooling purposes rather than for drinking purposes in people’s homes, could it not be of a different standard? Why does it need to be of drinking-water quality?” Where, for instance, we want to use water for data centres, for growth, why do we not—in a closed-loop system—use waste water? We have some legislation that has been drafted for the right purposes and sounds great—of course, a water company must produce water of drinking-water standard—but does it need to be of drinking-water standard if it is being used to cool machinery?
