Managing Flood Risk

Geoffrey Clifton-Brown Excerpts

Monday 3rd March 2014 Commons Chamber

[Geoffrey Clifton-Brown (The Cotswolds) (Con)]

I am delighted to catch your eye in this important debate, Mr Speaker, and I will certainly adhere to your strictures. I am grateful for the opportunity to follow my hon. Friend the Member for Thirsk and Malton (Miss McIntosh), and I congratulate her on chairing the Environment, Food and Rural Affairs Committee and on her clear knowledge of this subject in her speech.

I want to cover succinctly aspects of the performance of the Environment Agency’s and the statutory water undertaker in my constituency, Thames Water. I will then consider some of the problems with the planning system, in particular building on a floodplain and the unknown and uncertain liabilities that has caused, and the difficulties with drainage and with insuring some of those houses under the new Government Flood Re system.

In common with a number of my hon. Friends, a number of houses in my constituency—often the same houses in the same streets—have been flooding for a number of years. This is not just water flooding; it is also sewage flooding. Water flooding is bad enough, but if a house is flooded from a sewer, it is twice as bad because it takes even longer to clear up. I want to examine critically the performance of Thames Water’s underinvestment in the sewerage system in my constituency. Areas of my constituency that are affected cover Moreton-in-Marsh, Fairford, Lechlade, Cirencester, Siddington and South Cerney, to name but a few.

I hold regular half-yearly public flooding meetings in my constituency. They are recorded, with action points, and bring together all the agencies—Thames Water, the Environment Agency, the county district council and relevant town and parish councils. In that way, I can hold officials to account.

[James Morris (Halesowen and Rowley Regis) (Con)]

My hon. Friend talks about bringing together the community around flood issues, but one point about resilience, particularly in my constituency, has been the work of the Halesowen flood committee led by Claude Mosseri and his wife Ruth. They have brought together the relevant agencies to do vital work around the Illey brook area of Halesowen. Resilience is very much about local communities taking local action to bring the agencies together.

[Geoffrey Clifton-Brown]

My hon. Friend is exactly right. Before I held the public meetings I found that each agency was shuffling responsibility off to one of the other agencies. It is essential that all agencies and all tools in the box are unleashed to try to solve these flooding problems.

The meetings have produced results in parts of my constituency, but there is still a lot to be done. In particular, problems with sewage flooding arise because the sewerage systems are very old. The moment we have any sort of flooding the water table rises, water gets into the sewerage system, and the pumps are incapable of removing the sewage from people’s houses, leading to very difficult issues. I will be encouraging Ofwat to take a greater interest in this subject—indeed, I will invite it to my public meetings—to see whether we can encourage Thames Water to carry out what it says it will, and invest more in our sewers.

[Bob Stewart (Beckenham) (Con)]

One problem seems to be that there is no way we can control the water table from going up and down. That is a severe problem, and there does not seem to be a technical solution to sorting it out. That is happening in my constituency more and more.

[Geoffrey Clifton-Brown]

I agree with my hon. Friend that whether or not climate change is taking place and is caused by human activity, there is no doubt that we are getting an increased number of events with increased rain intensity, and we must therefore have better defences against flooding. There is no reason in the 21st-century why we cannot have sewerage systems that cope with such events. In particular, as I shall come on to say, we need sewerage systems that will cope with new development, which often adds to existing problems.

There is a perception that the residents of the Cotswolds, who live 100 miles away from London but who are still in the Thames Water area, are getting a very poor deal. It is outrageous that all Thames Water customers will be charged an additional £70 to £80 a year for at least 10 years to pay for the huge Thames tideway tunnel, when we in the Cotswolds cannot get the increased investment we need to deal with sewage flooding. The regulator Ofwat has to look at that. The time for talking in the Cotswolds is over. Thames Water has had more than enough time to carry out all its design work. We need more sewerage investment.

Equally, we need the Environment Agency to take the lead in planning how to deal with catchment areas. An exchange took place with the hon. Member for Brighton, Pavilion (Caroline Lucas). The answer is not just dredging, but considering the whole catchment area using all the keys in our locker to deal with the problem. That is what I am asking the EA to do in my constituency. For at least three years, it has been talking about coming up with an upper River Churn catchment area plan, but I have still yet to see that plan. Not only do we need to see adequate investment from the EA to deal with river flooding problems, we need to encourage Thames Water to invest adequately to tackle sewerage problems.

On new developments, we have, unfortunately, seen a rash of developers in my constituency. I accept that we all need new houses because the population is rising, but we need—I say this most emphatically to my hon. Friend on the Front Bench—new houses in the right areas. If we build houses on floodplains we cannot complain when we get subsequent problems. In South Cerney, for example, a recently passed new development is right next door to an estate that has had sewerage flooding problems. How daft is that? Fairford and Lechlade have each seen new developments passed for developments to be built on the floodplain. That is also daft.

We need to examine the system we have at the moment. The Environment Agency is a statutory consultee for large investment, but it has to take into account only one-in-100-year events when considering whether a development on a floodplain is viable. That is completely unrealistic and should rapidly be brought down to a design phase of one-in-25-year events. The statutory water undertaker, Thames Water, is not even a statutory consultee; it is consulted by the local planning authority often only as a matter of principle. Even then, all it has to do is to say that the sewerage system is capable of being connected to the new development, not whether the new development will make existing sewage flooding worse or whether the sewer needs upgrading. This is a legal grey area. Thames Water has been taken to court several times for trying to exceed its powers. I say to my hon. Friend the Minister: for goodness’ sake let us look at this and try to get the legal framework correct.

An even more important aspect of the planning system is drainage: sustainable drainage systems. We are building up for ourselves a huge and unknown liability from the lack of proper design of drainage systems. Currently, the local planning authority monitors the drainage system for a new development. Developers, with plenty of funds behind them, employ clever drainage engineers who take their percolation tests in the summer when everything is nice and dry—when, of course, the drainage works properly—instead of being made to take them in the winter when the water table is high. They then ask the developer for a section 106 payment. Often, that payment is inadequate. Under the Water Bill, as my hon. Friend the Member for Thirsk and Malton knows, SUDS will have to be licensed by the county council. Until that happens, we have a huge and unknown liability from SUDS, which are often completely inadequate and designed for one-in-100-year events. I say again that they should be designed for one-in-25-year events. We should not be building willy-nilly on the floodplain without thinking seriously about what we are doing.

A lot of my constituents have difficulty getting insurance. The new Government Flood Re system will not cover houses built after 2009, so, in relation to all recent applications where houses have been built on the floodplain, we are creating a problem for ourselves. They will undoubtedly flood at some stage, yet the owners of those houses will not be able to get flood insurance.

I welcome the Government’s efforts to ensure that everyone who buys a house on a floodplain is aware of having done so, but it is one thing for people to be aware of it during the sunny summer months when they buy their houses, and a completely different thing for them to be aware of it in the winter, when the rain falls in bucketfuls.

[Adam Afriyie (Windsor) (Con)]

Like my hon. Friend’s constituency, mine has been pretty much under water. Does he agree that if we go ahead with many of the proposed flood alleviation schemes—the bigger schemes that are intended for the future, such as the extension of the Jubilee river all the way down to the Thames—far more land will come back into use, and we shall need better planning control to ensure that the flood meadows are not removed from the current system?

[Geoffrey Clifton-Brown]

My hon. Friend is entirely right. If we concrete over vast areas, particularly on the floodplains, they will no longer be able to absorb water, which is what they were designed to do in the first place. In many instances, they were designed specifically as flood meadows. Worse still, in the event of heavy rainfall they will empty the water into the catchment very quickly. That is what has caused flooding downstream.

I suggest to the hon. Member for Brighton, Pavilion that we should consider the catchment areas as a whole, and decide how best to deal with what are to remain floodplains. In my constituency there is a scheme enabling water above Cirencester to be impounded so that it can be gently released when the rainfall has subsided. We should be doing much more of that sort of thing, because it is much cheaper than building expensive houses and then having to provide flood defences retrospectively.

Let me say to my hon. Friend the Minister that, while I commend what the Government have done, we need to look carefully at investment, particularly investment by the water undertakers. It is not a question of public funding; it is simply a question of equity between the profits that are given to shareholders and the profits that are reinvested in sewerage systems. I repeat that it is outrageous that Thames Water is being allowed to charge my constituents between £70 and £80 a year for the Thames tideway tunnel when they are not benefiting from the investment in sewerage flooding systems that they justly deserve.

Let us, for goodness’ sake, look at the planning system. Let us not keep building on the floodplains, because doing so is creating a great many uncertain liabilities for the future.

[Barry Gardiner]

I am sorry; the Minister is wrong on that point. The 290 projects that I referred to are those that were shovel-ready and scheduled within that four-year period; the 996 projects are the ones that were not. Significantly, 13 of those schemes were in the north-east Thames valley, where more than 350 homes have been flooded, and 67 of them were in the south-west, where 100 homes have been flooded.

My right hon. Friend the Leader of the Opposition made the further point at Prime Minister’s questions that the EA is planning to make 550 flood defence posts redundant. I specifically questioned the Minister in the Westminster Hall debate last week on whether those redundancies will go ahead. He was pressed for time in his summing up and was unable to explain how he considered that the EA could give people the sort of assistance that we have seen over the past two months and to which many hon. Members have paid tribute this afternoon, and I join them in doing so. How will the EA do that with 550 fewer staff? Today, I ask him to tell the House what roles the people in those posts currently perform. Are some of them the people who actually manage the flows of water in the waterways, by monitoring and operating the sluice gates, the weirs, the locks and the pumps? Do they include the people who survey and assess the condition of flood defences. Do they include the people who prepare the maintenance schedules for those defences? Do they include any of the people who have been helped with the clear-up operations? What is of enormous concern is that those skills and expertise might be lost with these redundancies, with the corresponding loss of service and safety to the public in the future.

[Geoffrey Clifton-Brown]

Will the hon. Gentleman give way?

[Barry Gardiner]

I am afraid that I cannot give way because I have to give the Minister time to respond. I have given way quite a lot.

Now the Government have set out their forward projects for capital, by saying that they will spend £370 million a year in 2015-16 and every year through to 2021. The Minister needs to be open with the House today about what percentage of that money in each year will be used for new build flood defences and what will be used for major capital repairs and maintenance. The Committee on Climate Change has been astute in analysing the figure of 165,000 properties that the Secretary of State told our Select Committee were “better protected” in the current spending period when he gave evidence to us last year. It warns that flood risk will actually reduce only for a proportion of the 165,000 properties. Many capital schemes are simply replacing or refurbishing existing defences on a like-for-like basis and to the same crest height. With climate change, many of those homes will be less well protected than when the defences were originally built. The defence may have been repaired, but the risk that it will be overtopped as a result of climate change has increased. Far too many homes and properties are still at risk because the defences that we have are less effective than they once were because of the increased frequency and severity of extreme weather.

As my right hon. Friend the shadow Chancellor pointed out in his op-ed for The Daily Telegraph just over a week ago:

“Investment in flood defences is now £500 million below what is needed and this risks £3 billion in avoidable flood damage”.

The point that he makes is as simple as it is clear:

“we need to make long term decisions now that can save money in the future”.

He has promised that our zero-based review of public spending must not only eliminate waste and inefficiencies but

“prioritise preventative spending that can save money in the long-term.”

That is the sort of commitment that people get when they have a Chancellor who understands the science of climate change, rather than one whose guru is the chief climate change denier in the other place.

As my right hon. Friend the Leader of the Opposition said on Wednesday last week, the assessment of how much to invest in flood defence depends significantly on an assessment of the risks posed by man-made climate change. If we are properly to protect the British people against the threat of flooding, we cannot have doubt and confusion within the Government on climate change. But doubt and confusion are what we have from the two Secretaries of State in charge of protecting our homes, infrastructure and industry. The Environment Secretary’s unscientific opinions on climate change and his refusal to be briefed by his chief scientist on the subject are a matter of public record, as is his decision to downgrade flood defence as a priority. The link is clear.

The confusion reached a new height last Wednesday when the Communities Secretary, given the opportunity to show some scientific understanding and rigour, chose instead to cite Lord Lawson. The noble Lord’s dangerous, unscientific opinions on climate science are well known and have no place in the Government, let alone in the answers from a Secretary of State with responsibility for flooding. The fact that the Prime Minister has refused to distance himself from those comments shows that the Government cannot be trusted to get this right. The Met Office has been very clear that such extreme weather events as we have seen are only likely to become more severe and more frequent.

Is the Environment Secretary still refusing to entertain a briefing from his chief scientist on climate science? Will the Minister at least put his own opinion on the record? Does he accept the climate change risk analysis prepared by his officials, which estimates that 1 million properties may be at serious risk of flooding by 2020? Up from the current figure of 370,000, that 1 million estimate includes 800,000 homes. If so, will he tell us whether his Department’s flood insurance proposal—Flood Re—takes account of those additional properties? The Committee on Climate Change adaptation sub-committee has warned that it does not.

The Minister will know that Lord Krebs, as chair of the adaptation sub-committee of the Committee on Climate Change, wrote to the Secretary of State in January and made it clear that the committee was available to the Department to ensure that sound science was the basis for all the Government’s long-term funding decisions on flood defences. Will the Secretary of State accept that offer?

I wish to identify one of the most fundamental recommendations made by the Select Committee in its excellent report. The Committee stated:

“We regret that the current regulatory framework does not permit innovative investment in natural flood defences by water companies and expect Ofwat’s next Price Review to rectify this.”

All too often, we reach for concrete and steel solutions to the problem of flooding instead of looking at soft, green infrastructural approaches. There are notable exceptions, and Wessex Water, for example, operates a catchment management system that pays landowners to manage the uplands in a benign way that retains water and purifies it, instead of allowing contaminated water in need of treatment to run swiftly down the catchment. Land management plays a vital role. The retention of flood water upstream through woodland and ground cover in the uplands is every bit as important as dredging in the lower levels of the catchment. Landowners always seek to dredge the river as it passes through their land. That is the quickest way to try to ensure that their own land is not flooded and the problem is passed downstream. This approach was contained in the Pitt review under recommendation 27. When will this most important element of flood risk management, adverted to in the Select Committee report, be implemented?

[Dan Rogerson]

The figures that I am setting out into the future are for capital spending, and we expect revenue amounts to be settled as budgets are introduced for each year. However, the points that the Chair of the Select Committee makes about seeking contributions from all those involved in water management are entirely valid. In her speech she spoke about water company investment in water management that goes beyond the “hardware” side of things and looks more at the softer side of managing water through land management solutions. Ofwat is considering what it does with totex—total expenditure. It is looking at expenditure across the piece, rather than just at capital—the sort of things that appear on balance sheets that, in the past, would have been the focus. I accept that many people want to change that, so the fact that Ofwat has allowed water companies to do more of that will be beneficial.

The right hon. Member for Exeter (Mr Bradshaw), who is not in the Chamber today, but who took part in the Westminster Hall debate, pointed out the involvement of South West Water, along with my Department, landowners and managers, in an initiative looking at how water can be retained on Exmoor, which has made a difference to the moor’s catchments. That is a good example of the sort of work that can take place. The Chair of the Select Committee often speaks about what is happening in her constituency with the “Slowing the Flow” project, which is working on land management solutions. She is absolutely right that we need to emphasise the economic importance of investment in flood defences and, indeed, in water management. If we can prevent flooding and take that blight away from land that could be developed successfully, that would make a big contribution. If we can avoid the impacts that hon. Members have discussed, we can make a huge difference to local economies.

[Geoffrey Clifton-Brown]

Will my hon. Friend address the points that I made in my speech about building on the floodplain and, where it is not his ministerial responsibility, undertake to have a discussion with his colleagues in the Department for Communities and Local Government to address the uncertain but doubtless growing liabilities in Flood Re and SUDS, so that we do not build up a bigger and bigger problem for ourselves in future?

[Dan Rogerson]

My hon. Friend made that point earlier, and a number of other Members referred to the planning process. The good news is that the advice that the Environment Agency gives is taken into account in the vast majority of circumstances. However, there may be examples where we could look at that. My right hon. Friend the Secretary of State for Communities and Local Government, who has discussed the response and recovery aspects of these flooding events at the Dispatch Box on a number of occasions, will have heard that cry, and the national planning policy framework, which the Government have set out, makes it clear that we should not build on floodplains. There are locations, such as those, as we have heard, in the Humber area and so on, where that means no development at all, and the guidance makes it clear that we should see more resistance and resilience built into existing properties. The hon. Member for Brighton, Pavilion (Caroline Lucas) made that point in response to an intervention.
