South East Water: Disruption of Supply

Helen Grant Excerpts

Wednesday 3rd June 2026 Commons Chamber

[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?

South East Water has openly and publicly admitted that it cannot supply drinking water for all the future homes that are planned for Kent. What is the Minister’s response to that specific concern, and is she having conversations with her colleagues in the Ministry of Housing, Communities and Local Government?

[Emma Hardy]

The short answer is yes. The previous chief executive of South East Water—or rather the current chief executive, who has not gone yet—met members of the water delivery taskforce a few weeks ago, with some of the councillors from the area, to discuss exactly that issue of how both water supply and housing demands can be met. I sit on the taskforce along with representatives of the Ministry of Housing, Communities and Local Government, so we are all having the conversation together about how we build the homes that are needed without having an impact on the people already living in the area, yet also ensuring that new homes have the water that they require.

We have been assessing what is likely to happen over the next five, 10 or 15 years. What are the various water supplies that will be coming in? What impact will that have on house building? How can homes be built to a more water-efficient design? Those conversations are happening now, across Government. We need to achieve the right balance between ensuring that everyone has a home to live in and, at the same time, preventing a water crisis?
