Water Scarcity

Danny Chambers Excerpts

Tuesday 9th December 2025 Westminster Hall

[Jim Shannon]

I think the two words “immoral” and “obscene” sum up the issues that the hon. Lady has referred to, and we look forward to the Minister’s response.

In 2024, Northern Ireland Water published a new water resource plan, extending its long-term planning horizon from 25 years to 50 years, so it has in place a structure to look forward at what will happen in Northern Ireland. Our population has increased by, I think, more than 200,000 in the last 10 years. The increase has been quite significant. There have been large developments. My constituency of Strangford has experienced that. There is a development coming through in the east of the town. There will be 750 new houses, and that will add stress on the infrastructure, including the water system and all the roads. But we have to address population growth, housing demand, water usage and climate change. The plan recognises that future weather patterns are likely to include more frequent extreme events, and pledges to build resilience so that the water supply remains secure.

[Dr Danny Chambers (Winchester) (LD)]

This is the first time I have intervened on the hon. Member—it is normally the other way round. He mentioned climate change, and I was alarmed to read that last year Hampshire and Isle of Wight Fire and Rescue Service attended 197 outdoor fires and wildfires, which was one of the highest numbers in the whole of the UK. We are seeing water scarcity and abstraction from rivers against the backdrop of having had the 20-odd hottest years on the planet—year after year after year. It has to be acknowledged that that is affecting water scarcity as well.

[Jim Shannon]

The hon. Member highlights another issue in relation to climate change and the dry spells that we are having, which lead, ultimately, to the fires that take place, whether deliberately or by accident.

Spelga dam supplies most of the water for the Greater Belfast area, and that takes in the area that I live in, Strangford, and North Down, and goes down as far as South Down. I also want to refer to Lough Neagh in a few minutes. Water usage per person in Northern Ireland is rising—the hon. Member for Horsham referred to this issue in his introduction—and has exceeded 160 litres per day. The system is sensitive to dry spells. I am recalling the summer that we have just had and the Twelfth of July—this is a very important year for us Orangemen—when the weather was outstanding. So much more water was used for children’s play pools, sprinklers and watering plants. The weather should not be taken for granted and neither should the amount of water that we are using. That is what this debate is all about—how we use water better. The situation was similar to one a few years back in Northern Ireland. I remember that there was actually a hosepipe ban, involving restricted hours, to limit the amount of water that was being used. We have had drought spells in Northern Ireland in the past, but we do not really have much shortage of rain, by and large.

Water quality is also a big issue back home. Environmental concerns have been released by the Department of Agriculture, Environment and Rural Affairs on the safety of some of the water that it manages. Large bodies of water such as Lough Neagh, the UK’s largest freshwater lake—this has been in the headlines all over the United Kingdom, but especially in Northern Ireland—have repeatedly experienced toxic algae blooms. The issue is not isolated to just that location; it happens in other locations as well. Northern Ireland has also witnessed a risk to infrastructure and investment, which could have a direct impact on our drinking water supply. Funding constraints are always an issue, to the point that Northern Ireland Water has actually halted new wastewater connections for many new housing developments. It puts the onus on the developer to come up with the sewerage systems, come up with the water supply—come up with the infrastructure that it would normally put in—and the developer pays for that.

There are real issues regarding water scarcity back home. I always have great faith in the Minister in relation to her discussions with the relevant Minister in the Northern Ireland Assembly. I am always encouraged by the Ministers who come to these debates and whom I speak to, because when it comes to contacting the Ministers back home, by and large they have all done that. If this Minister has had that opportunity, what has been the outcome?

Water is not scarce in Northern Ireland, but there are many contributing factors that imply that the situation could get worse. On water condition and water access, more needs to be done to repair the damage and ensure that agencies such as Northern Ireland Water have the money that they need to improve our services. I look to the Minister to tell us what discussions and conversations she has had with the Ministers back home to ensure that we can address this issue centrally here at Westminster, but for the benefit of all the regions.
