The Minister of State, Department for Environment, Food and Rural Affairs (Emma Hardy)
I genuinely thank the hon. Member for Taunton and Wellington (Gideon Amos) for securing the debate. I really enjoyed listening to his speech. There was so much agreement from the Government side of the House on pretty much everything he said. He described what I would refer to as “pre-pipe”, which I am really interested in. It is about, exactly as he described, looking at how we stop rainwater ending up in our sewerage system and often contributing to pollution incidents—the system becomes overwhelmed —when, as it is rainwater, it could be elsewhere.
The hon. Gentleman touches on one of my favourite things to talk about: nature-based solutions—how we can use nature more, create soakaway areas and create sustainable urban drainage. That is absolutely correct. I am passionate about thinking about how we manage water. We often talk about how to solve problems around pollution, but if we better manage rainwater that falls from the sky, we can help to deal with pollution, as well as many other things. Reservoirs are hugely important, as my hon. Friend the Member for Bracknell (Peter Swallow) pointed out, and we should absolutely be using them, but they are part of the wider system—collecting the rainfall and putting it where we want it, rather than it ending up where we do not.
It is obviously for the Ministry of Housing, Communities and Local Government to talk about building standards, but I can tell the hon. Member for Taunton and Wellington, because I asked MHCLG ahead of this debate, that it is reviewing water efficiency standards in the building regulations for new homes, and considering how to enable water reuse systems, including rainwater and grey-water systems, where those are safe, practical and cost effective.
I have mentioned this issue a few times, and I share the hon. Gentleman’s concern—“astonishment” may be going a bit too far—that we use drinking water to flush our toilets. To give the other side of the argument, which I have had played back to me, the rules mean that the water supplied to domestic properties has to be drinking water quality. I hope that I am not telling the House things I should not, but we are exploring how we can guarantee that we do not mix up the water pipes that go into homes and therefore cause problems that way. This always has to be safety first. That is why the only water that can enter a property—unless a private individual has set up their own system—has to be drinking water quality.
Julia Buckley (Shrewsbury) (Lab)
Does the Minister agree that much progress has been made in regard to rainwater harvesting, not just by MHCLG but by the Minister’s Department—not least the landmark report, published this March, by the Drinking Water Inspectorate? The report exactly explored a potential governance framework that sets out standards for non-potable water in domestic settings, and talks about accreditation and standards, to ensure that these systems, when we are ready to bring them in, are safe and will be properly maintained.
Emma Hardy
I thank my hon. Friend; I was trying remember what the report was, so I very much appreciate the intervention. She is absolutely right. We have some of the best drinking water in the whole world; we have incredibly high standards for the health of our drinking water. The report by the Drinking Water Inspectorate looks at how we can do this in a safe way, and I am keen to explore that. We are going to be short of drinking water if we continue at this scale in the future. Thinking about where we are using it, rather than using it to flush our toilets, feels like a way forward. There is a huge amount of cross-party thinking on how we can do that. This comes back to the topic of how we manage water. How do we think about water? Where is it falling?
James Naish (Rushcliffe) (Lab)
The Minister is obviously aware of the work of the Labour rural research group. One thing we have been talking about is whether environmental land management schemes need longer-term certainty. Farmers are trying to invest in proper water management, as she is describing, but they often need more than three years to do so. Does she agree that her Department may need to look at how we can arrange for ELM schemes to be longer term, specifically when it comes to water?
Emma Hardy
I am hesitant to agree to something that is not in my brief, but I will certainly mention that to the Farming Minister, my hon. Friend the Member for Portsmouth South (Stephen Morgan).
The hon. Member for Taunton and Wellington is right that when we think about water management, we often talk about reservoirs; those are very much needed, and do matter, but so does managing water where it falls—thinking about roofs, streets, gardens, farms and developments. That is why we want a more practical, prevention-focused approach to water management that captures more water, wastes less of it and plans developments in a way that looks at local catchments.
Jonathan Davies (Mid Derbyshire) (Lab)
One thing that will benefit farmers in my constituency is the ÂŁ50 million through the sustainable farming incentive to allow farms to build more water storage on their land. That is going to be of huge benefit, because their food stocks are down going into winter after the hot summer. We also have an issue with flooding. Schedule 3 to the Flood and Water Management Act has not been enacted, meaning that every development has a right to be connected to the drainage system, which increases the amount of flooding. If the Minister could take that forward with colleagues at MHCLG, I would be very grateful indeed.
Emma Hardy
On the point about farm reservoirs, my hon. Friend is correct. Today I held a meeting of the national drought group, and we had a focus on agriculture and the impact that drought has had on farmers. We are talking now about potential rain, El Niño and flooding, but drought is still here in this country. One of the conversations we had was, how can we support farmers to hold more of the water that comes down from the sky? We are focusing a lot on funding farm reservoirs, but we also need to think about filling farm reservoirs. How can farmers get them full for the summer, which we need, given our changing climate, with more rain in winter and drier summers?
I love SUDS—I get very geekily excited about sustainable drainage systems. I know I am shocking you, Madam Deputy Speaker, but I will try to convince you that they can be really nice, and they can be spaces for nature as well. I am not winning, am I?
Peter Swallow
I completely agree with the Minister. There are many SUDS in Bracknell Forest that have been delivered as part of alternative natural green spaces, and they create lovely nature corridors in our community. I just wanted to put that on the record.
Emma Hardy
This is like geeks united—we love our SUDS! They are brilliant.
The hon. Member for Taunton and Wellington is right: the point about the maintenance of SUDS has been raised a few times. It is okay to build them—I actually think most are built and designed in a very effective way—but there is also the question of how we ensure they are maintained and who is responsible for that.
Gideon Amos
I just want to make an observation. When I trained as an architect, I had to follow a whole series of regulations on drains about what the diameters are, what the gradients are—everything has to be followed. For SUDS, there are no such regulations. One is regulated; the other is all down to policy. As many Members have said, we need proper regulation for SUDS, because things will go wrong if we do not get schedule 3 or similar legislation on to the statute book.
Emma Hardy
I thank the hon. Gentleman for the expertise he brings to this House from his previous occupation. That is one of the things we are trying to work through with industry and MHCLG. We all agree that SUDS are a really good thing. Where they may not be as effective is the maintenance issue: who is responsible for maintaining them, and who pays for it? That is the kind of thing we are thinking about.
This goes back to the point I made earlier. When it comes to planning, are we thinking about the management of water in an area? With our changing climate going from drought to flood, are we thinking about where we want the water? It is a slightly different, nuanced conversation to say, “When it floods, where do we want the water to go? When there is a drought, where are we going to get the water from?” That means thinking about it more holistically in a way that we have not done previously, when we thought about each point in isolation.
Richard Foord (Honiton and Sidmouth) (LD)
In January last year, Storm Chandra caused devastation in East Devon, and there was significant flooding in Ottery St Mary. Does the Minister think that, as well as attenuation ponds and SUDS, people should be encouraged to store water in their own gardens using such things as water butts?
Emma Hardy
Absolutely; the more we can all do collectively, the better. We are coming up to Flood Action Week, beginning on 12 October, when I will be calling on every single Member in this House to do what they can to get the message out to their constituents about being prepared and how we can all collectively play our part in what could be quite a challenging winter.
The national planning policy framework requires all new developments to incorporate SUDS designed and maintained in accordance with national standards. There are some new national standards, and the hierarchy within those standards prioritises collecting rainwater for non-potable uses. We are also committed to better joined-up water planning, with decisions on housing, drainage, water supply and waste water taken together, so that growth is supported in the right places and communities are better protected.
In conclusion, I have really enjoyed this debate and talking about some of my favourite things: natural flood management, SUDS, rainwater and water management in a catchment—it has ticked all my favourite boxes. Managing rainwater where it falls is practical, local and important. It can help households to use less mains water, reduce pressure on sewerage, improve drainage, support flood resilience and make new developments more sustainable. That is why this Government continue to support better management of rainwater. Our water system faces significant challenges, but this Government are taking action, cleaning up rivers, tackling pollution at source, holding water companies to account, improving resilience to flood and droughts, and securing investment needed for the future. Through reform, investment and stronger regulation, we are rebuilding public trust and creating a water system that works for people, the environment and our economy.
