I beg to move,
That this House has considered plans for a Thames Water reservoir at Abingdon.
I am grateful for the opportunity to appear before you, Mr Stringer, and to raise this important subject. Obviously, it is the perfect day for a Conservative MP to open a debate about digging a very large hole.
It may interest Members to learn that, for the last 20 or 25 years, there has been a proposal to build a large reservoir in my constituency. It is known as the Abingdon reservoir, which reflects the name of the constituency of my neighbour, the hon. Member for Oxford West and Abingdon (Layla Moran). However, it would be situated in my constituency, near the villages of Steventon, the Hanneys and Drayton. This is a very large piece of land—probably one of the largest pieces of open land in the south-east of England. There have been various thoughts about what might be built on that land, including, amazingly, an airport and a garden city. However, the reservoir has been the most enduring proposal.
I am neutral about whether the reservoir should be built. On the one hand, I am a nimby, and it would make my life a lot easier if a reservoir was not built in my constituency; on the other hand, I recognise that it is potentially a large and important piece of infrastructure for the south-east of England. One thing that I am firm about is that the reservoir should not go ahead unless the need for it has been properly examined. I was successful the last time construction of the reservoir came close to happening, in 2010. I called for a public inquiry, which we secured, and which rejected the need for a reservoir. For me, it is unarguable that there should be a second public inquiry if Thames Water, which is behind the proposal, comes up with a proposal for a reservoir.
At the moment, Thames Water is developing its statutory water resources management plan, which the regulator requires of water companies to allow them to put forward proposals that will ensure a secure water supply and protect the environment. The reservoir is being presented by Thames Water as a solution for long-term water shortages. I will rehearse some of the arguments for and against the reservoir, and then ask the Minister a number of questions.
I do not think anyone would disagree with Thames Water, or indeed other stakeholders, that there is severe pressure on water resources in the south-east. As I am sure many people in this room who are knowledgeable about this subject know, it is a great irony that we live in quite a rainy country but that we still have great pressure on water resources and do not have as much rainfall as required. Thames Water estimates that by 2045—in another quarter of a century—it will need to find an extra 350 million litres of water per day to supply the population in London and the south-east. It is working with other companies as part of the Water Resources in the South East group to look at the long-term needs of the wider region and the best options for strategic water supply. According to Thames Water, the reservoir option will improve its resilience and that of Affinity Water by creating a regional storage and transfer hub.
Thames Water bases its estimate of the extra 350 million litres a day on a population increase forecast of 2.1 million over the next 25 years, which translates into an extra 1.3 million houses, and on climate change projections—for the avoidance of doubt, I am not a climate change denier, and I accept that climate change will absolutely have an impact on water supply in the south-east. Thames Water forecasts that, by 2050, our summers may be an average of 3° hotter and 18% drier. The Environment Agency’s welcome tightening of regulatory oversight also makes it harder to extract water from rivers and underground sources.
There is perhaps a slight contradiction: on the one hand, there is great concern about a reservoir in my constituency, but on the other hand, my constituency is home to some of the chalk streams of south-east England, including Letcombe brook. I have two little-known facts for hon. Members about chalk streams. One is that 85% of the chalk streams in the world are in the south-east of England, while the other 15% are in Normandy because they are part of the same chalk ridge that was once fused together when we were members of the ice age version of the European Union. My other little-known fact is that somebody who is passionate about chalk streams is the former lead singer of the Undertones, Feargal Sharkey, whom I got to know when he was head of UK Music and I was the Culture Minister responsible for music. I spoke to Feargal this morning and he made a point that I will bring up in my conclusion: a reservoir has not been built in the south-east since 1976.
To make a wider and less reservoir-focused point, there has not been investment in water storage for some 40 years. Increases in housing and population, climate change and tighter environmental regulation will result in average daily consumption per person rising from 1,300 litres to roughly 1,400 in the next few years. I should also say that one of the arguments that came up when a reservoir was debated almost 10 years ago was the desire to see Thames Water do more to tackle leakage. London suffers from having Victorian infrastructure; we lose an enormous amount of water through leakage. I am pleased to see that Thames Water wants to reduce leakage by 15% by 2025 and 50% by 2050, but that will still not be enough to supplant the increase in demand for water.
Thames Water says that it has looked at several options, including water transfer from the River Severn; making more water available from the remaining power station at Didcot, where the coal-fired power station has been closed down; water transfer from the midlands via the Oxford canal; and a reuse scheme at the Deepham sewage works. However, it has reached the conclusion that the reservoir is the best option and that the site in my constituency is the best of the 50 sites it claims to have surveyed.
Obviously, Thames Water wants to emphasise some of the benefits that might come to my constituents, including nature conservation, new natural habitats, opportunities for recreation such as fishing and walking, and the opportunity to reduce abstraction and save our vulnerable chalk streams. It is also keen to lay to rest the accusation that it is undertaking this infrastructure scheme in order, frankly, to line its own pockets. Apparently, any reservoir would be constructed under the same financial arrangements as the Thames sewer, with a separate company and additional money on our bills for some 40 years until the construction cost has been paid off.
My constituents, particularly those local to the site, have certainly not taken Thames Water’s proposals lying down. I pay tribute to Brigadier Nick Thompson, who led the Group Against Reservoir Development in its first battle when there was a public inquiry, and to Derek Stork, who now leads GARD. Given that this is happening in my constituency, I am pleased to say that the average resident has quite a bit of ammo behind them; Derek is the former head of technology at the UK Atomic Energy Authority, so he is no slouch when it comes to looking at the issues with his colleagues.
GARD points out that filling the reservoir would take three years and cause immense damage to the local community, the landscape and archaeology. The reservoir would have walls 25 metres high and would take 30 days to drain in an emergency. Building it would be enormously disruptive to the local community and would take something like 10 years, with all the resulting lorry traffic and disruption.
My constituents have already been affected by the very serious matter of planning blight. For example, many landowners have not modernised their buildings in the past 20 or 30 years; their land is still being used mainly for farmland because the threat of a reservoir has been hanging over them. They require certainty. Last year, a constituent was unable to sell their home, and I had to bring Thames Water to the table to purchase it. Many others who live near the site find that it is having an impact on their house prices and the opportunity to sell, and some of them face negative equity.
What concerns my constituents is not just the building disruption, but whether the case has genuinely been made. They have taken on some of Thames Water’s assumptions: they think that its population forecast and usage projections per person are unrealistically high and, although they are certainly not climate change deniers, they challenge its forecast of the impact of climate change on water availability. The data shows that water availability in London has increased over the past 70 years by about 200 litres a day. My constituents are not necessarily making the case that there should never be a reservoir, but they certainly do not believe that one is needed now; in fact, they argue that if there is ever a case for one, it will not be needed until at least 2100.
Given what the right hon. Gentleman says about the degradation of the river system, especially the chalk rivers, the clock is ticking and there is an imminent crisis, as Feargal Sharkey would say. I do not want to bring the debate back to Europe, but it is 45 years since we have been in Europe and 42 years since we built a reservoir. Does the right hon. Gentleman not conclude that the clock is ticking for us to save our river system in the south of England, especially the chalk stream system?
The hon. Gentleman makes a valuable point. Obviously I am focusing on the specific proposal for a reservoir, but there is a lot more to say about managing water resources in the south-east. GARD is not saying that we should not build any more infrastructure to make more water resources available; it is saying that the Severn transfer option is viable and cheaper, and there is also the possibility of the Teddington abstraction scheme. Thames Water itself acknowledges that water transfer is an option, although it argues that it is not as good an option as a reservoir. It also claims to be looking at the Teddington scheme.
I want to give other hon. Members a chance to make the points that need to be made, but I want to ask the Minister about a number of points. I would be grateful for her insight into what work the Department has done with Thames Water to assess not just its proposal for a reservoir but its overall water resources management plan. Will she assure me and my constituents that, as this journey continues, Thames Water, her Department and other stakeholders, such as the Environment Agency, will fully involve my constituents in their deliberations and consultations? I hope she will support me, my constituents and Oxfordshire County Council in calling for a public inquiry to ensure this process is conducted in an open and proper manner.
I will draw my remarks to a conclusion by making the following points. When I sat firmly on the fence about the reservoir a decade ago, I must confess that I was not entirely confident that a public inquiry would lead to the reservoir being dismissed. I was pleasantly surprised that the inquiry concluded that a reservoir was unnecessary. It is sometimes easy to dismiss local campaign groups as nimbys or as people who will find almost any way to stop any kind of development near where they live, but, as it turned out, the campaign group defeated Thames Water in a sort of David and Goliath battle with the power of its arguments. The planning inspector found that Thames Water had not made its arguments effectively. I do not think that a lot has changed since 2010 or that the alternative options have been explored fully, and they need to be.
On the point the hon. Member for Dagenham and Rainham (Jon Cruddas) made about chalk streams and the environment, I have one other element of frustration, and it is partly directed at the Minister—her post, as opposed to her personally, because she is obviously a very good friend of mine. It seems slightly odd that Thames Water, a private company, is being left, to a certain extent, to its own devices to come up with a solution to a potential water crisis in the south-east over the next 10 or 20 years. It would be much better if this whole debate were led by the Government. They should say, “This is the need over the next 25 years. This is our best guess—made on all the available expertise, in a dispassionate fashion. These are the best ways to combat water shortage. They are about not just tackling leakage and more efficient home use, with water meters and the like, but realistic infrastructure that provides the best access to water resources with the minimum disruption to communities.”
I am delighted, at what I think is still quite an early stage in this process, to have had the opportunity to raise these issues at the highest level.
I was not going to speak this afternoon; I came to listen. There is a little bit of time left so I will say a few words, but I will not take up too much of Conservative Members’ time: they obviously have urgent meetings on the Estate to get to over the next couple of hours, as their party disintegrates.
The two speeches that have been made were very thoughtful and contained nuanced arguments about the case for and concerns about the reservoir. I came to listen because, although this is primarily a local matter, it throws up a lot of issues about ways in which we can achieve new water; the supply, distribution and quality of new homes; the role of the water companies themselves; and patterns of regulation—to name but a few.
I congratulate the right hon. Member for Wantage (Mr Vaizey) on securing the debate. I know something about it because of my interest in chalk streams. As I understand it, Thames Water announced its new plans to start construction on the reservoir in 2025. I totally understand the local concerns that have been registered about the proposal, because it was rejected in 2010 at the public inquiry. There is a general concern that, to satisfy growth in London and the south of England—another consultation is ongoing—the Thames Water plan for the reservoir suggests a storage and distribution hub for the south-east.
Objectively, it seems clear that we need new water and new infrastructure, including reservoirs. I accept, however, that there are other suggestions for bringing new water into the stressed south-east, including transfers from Wales and the River Severn, or water re-use and desalination. There are a whole number of other proposed remedies.
One point I want to flag up that has been mentioned in the debate but which is often overlooked in the case for any new supportive water infrastructure, is the degradation of the river systems in England—specifically, of the chalk streams. As the right hon. Member for Wantage mentioned in his speech, England has a unique concentration of chalk streams—160 of the 210 that exist globally—and they are disproportionately in the south of England. Yet they are in an appalling state; no water is moving in many of them and there is no flow. More generally, I recently saw data that estimated that only 14% of the rivers across England are considered to have reached good ecological standards. At the same time, demand for water, especially through new house building in the south of England, has dramatically increased.
Those two apparently separate issues are intrinsically related. A policy failure to provide new water means that our water companies extract water from our rivers, which cannot cope and subsequently die. At the same time, excess sewage is discharged into the rivers by those same companies, further undermining their quality and sustainability. Time and again, the water companies have been fined, but they take the hit—there are notorious cases of discharge by Thames Water. In effect, they free-ride their ecological responsibilities.
The situation has to be sorted out via public policy making because, as a consequence of all this, it has been 42 years since we have built a reservoir. The right hon. Gentleman, when introducing the debate, intimated that he was moving closer to Labour’s policy on water ownership and frustrations with the current system. Responsibility lies with a number of different authorities: the Environment Agency, the National Rivers Authority, the Government and the subject of today’s debate, Thames Water.
I repeat that I do not want to stray into local planning consultations, and I respect the contributions to the debate so far, which have made powerful cases, but an overall case needs to be made on consumer demand and preserving our unique English river systems, especially in the south of England: new infrastructure is needed. That does not mean that I am in the pocket of the water companies, but consequential environmental issues are involved, and the clock is ticking. New build, or the start of the build, in 2025 is being talked about, but any cursory look at the English river system tells us that we need urgent action now.
