Water Scarcity

Alison Bennett Excerpts

Tuesday 9th December 2025 Westminster Hall

[Alison Bennett (Mid Sussex) (LD)]

It is a pleasure to serve under your chairmanship, Mr Stuart. I thank my neighbour, my hon. Friend the Member for Horsham (John Milne), for securing this important and timely debate.

Over the past week, my constituents in Mid Sussex have watched the appalling situation in Tunbridge Wells—families left without water for days on end, businesses forced to close and vulnerable residents unable to wash or cook—with deep concern. South East Water’s handling of the crisis has been nothing short of shocking. My constituents are asking the very reasonable question, “Could we be next?”.

While we accept that climate change is affecting rainfall, and recognise that house building places additional pressure on supply, none of that excuses the simple truth: South East Water has failed to invest properly in its network, failed to maintain its pipes, and failed to plan to ensure resilience. We have also not seen a major new reservoir in England since 1991. In Mid Sussex, we are now seeing the consequences of that neglect. Ardingly reservoir is at 44% capacity—this time last year, it was full. We have had a hosepipe ban imposed since the summer, businesses have been restricted under a drought order and South East Water is now racing to design a 13-kilometre pipeline to move up to 30 million litres of water a day from Weir Wood reservoir, just to keep Haywards Heath and surrounding villages supplied next spring and summer. That is not resilience; they are chasing their tails. The pipeline proposal raises serious questions. Its route would cross private land, roads, railway lines and environmentally sensitive areas, including Ashdown Forest. Local people deserve clarity, they deserve transparency and they deserve independently verified information, not only on the feasibility of the pipeline, but on every contingency plan the company claims to be developing.

I call on the Minister to go further. We need a full assessment of South East Water’s long-term resilience and investment strategy. We need clear, published forecasts of supply risks for every community and we also need regulators to ensure that companies owned by far-off investment funds are delivering water security, not just profits. Most of all, we need to protect our residents. Households, care homes, schools and businesses cannot simply be left to hope for rainfall or trust in last-minute engineering projects.

My constituents expect—and deserve—reassurance that the disgraceful scenes in Tunbridge Wells will not be repeated in Haywards Heath, Burgess Hill, Lindfield, Cuckfield or anywhere else in Mid Sussex. It should be a given, especially with rising bills, that people can live safely in the knowledge that they have access to a clean, reliable water source. For a Government with massive housing targets, it is unreasonable to expect local people to support targets of more than 1,000 homes per annum that are being delivered when they know that the existing population’s water demands are, at best, precariously met. That breaks the social contract. I draw my comments to a close there, but I look forward to hearing how the Minister plans to ensure that the situation is better managed in the future.

[Emma Hardy]

Apologies, Mr Stuart; I should gaze upon you at all times.

Protecting customers, of course, must be one of the top priorities, so I have been chairing one of the multi-agency responses. Normally agencies talk to agencies and Government, but I felt the need to intervene personally in this matter—which I have done three times in the last week—to look at every step that has been taken to resolve the issue, and particularly the concern around communication and making sure that vulnerable people are getting the water that they need.

[Alison Bennett]

Does the Minister support Liberal Democrat calls, including those of my hon. Friend the Member for Tunbridge Wells (Mike Martin), for the chief executive of South East Water to resign over this issue?

[Emma Hardy]

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.
