Flood Defences

Debate between Lord Benyon and Baroness Blackwood of North Oxford

Tuesday 21st February 2012 Westminster Hall

[The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Richard Benyon)]

I congratulate my hon. Friend the Member for Oxford West and Abingdon (Nicola Blackwood) on securing the debate and her reputation around Whitehall as a doughty champion of her constituents. I am delighted to respond to her concerns about the replacement of the manually operated paddle and rymer weir at Northmoor with a mechanised radial gate system.

My initial reaction was similar: how can the Environment Agency justify spending £2.5 million on a weir when the money could be better spent protecting people and property? I can appreciate people’s frustration with the expenditure of such a large sum of money on the works and with two summers of disruption in the constituencies affected, apparently just to meet a health and safety requirement with little flood risk benefit. My hon. Friend also expressed concerns about the decision to proceed without undertaking a full assessment of the flood benefits of the new structure. I shall take those points in turn.

First, I ought to set out the Environment Agency’s case for replacing the structure. A succession of weirs along the Thames, some in my constituency, regulate water levels. In a flood event, it is vital that the weir does not obstruct the flow of water, otherwise the north side of the river—in the case of the Northmoor weir—will flood.

[Nicola Blackwood]

The Environment Agency has confirmed that the replacement of the Northmoor weir will not improve the flood risk. Is the Minister claiming that the replacement of Northmoor weir is to improve flood risk?

[Richard Benyon]

I shall come on to that, because there is a flood risk issue, which I will cover later in my remarks.

The Northmoor weir is one of five major weirs being replaced as part of a single contract. The other four are already under construction or are now in place. The high price tag is a consequence of the size of the structure: the weir is more than 22 metres wide, stretching right across the Thames. The replacement has a predicted operational life of at least 60 years, and similar structures elsewhere have already proven effective and reliable. The problems with the existing weir structure have been known for some time.

During flood conditions, Environment Agency staff must lift an effective weight of up to 60 kg to shift the paddles. That is four times the safe working load recommended by the Health and Safety Executive. It is just about possible for two people to operate the paddles together, but at an awkward angle and at twice the safe working load. In the mid-1990s, an attempt was made to find a cheap and cheerful approach to solving the problem by replacing the wooden paddles with fibreglass. That reduced the weight of the paddles, but did little to solve the real problem. The sheer force of water, particularly on the deeper paddles, makes the job hard.

Two independent reports have been produced on the operational risks involved. As well as the weight, manual operation of the weir in response to flood alerts means working in difficult weather conditions for several hours. It is dangerous and tiring work. There are many weirs and gates along this stretch of the river that all need to be operated in tandem to prevent flooding of the houses to the north of the river. That is a key point. The structures need to be operated quickly when flooding is predicted, and an injury to a staff member halfway through would exacerbate local flooding.

[Nicola Blackwood]

First, will the Minister accept that, despite those working conditions, there is no record of any serious injury on the weir? Secondly, will he accept that the number of properties directly affected are, as the Environment Agency stated at the December meeting, five?

[Richard Benyon]

If the weir does not work, properties will be flooded. We can argue that the existing paddle and rymer weir works perfectly well, but as my hon. Friend knows, the Environment Agency has received consultants’ reports stating that the working load is way in excess of what one would normally allow for employees. I am sure that that she would agree that she and I as employers in business would have to take note of advice that is given. One always tries to do that proportionately, but it must be understood that the advice was given. It would be difficult for the Government to sit at arm’s length and ignore advice that the loading is four times too high and the risks that emanate from that. It is difficult for Ministers to overrule such advice, but I will talk about that further.

The Health and Safety Executive has seen the reports from the Environment Agency and the Appleton Weir Action Group and has written back in support of the agency’s position. As a responsible employer, the Environment Agency cannot ignore the advice of the Health and Safety Executive. Sitting back and doing nothing is no longer an option. The weir clearly poses risks to those who must operate it and to those live in the neighbouring constituency. An assessment of risk is not just about whether there have been accidents, but about the potential for accidents. I am a sceptic of all matters relating to health and safety, and I do not come to the matter as a quisling of the health and safety industry, for that is what it has become. I come to it as a sceptic, like my hon. Friend. I have looked at the matter in great detail, and if I were an employer on the board of the Environment Agency, I would find it difficult to ignore the report.

That brings me to the flood benefits of the weir, and why they have not been assessed for this project. The flood risk in the area is well known. Around 80 houses behind the north bank have a 1% chance or greater of flooding each year. In flood conditions, the Northmoor weir is opened, so that flood water can pass through as quickly as possible. The relationship between the weir structure and flood risk is well understood and would not benefit from further investigation. Doing that would have added unnecessary and damaging cost to an already expensive project.

[Richard Benyon]

During my long discussions with the Environment Agency, I became convinced that it really does understand the flood risks. I do not believe that it spends money without looking carefully at the alternatives. I have seen all eight or nine alternatives that have been presented—many of them were untried and untested as a means of lifting the paddle and rymers out using mechanical systems—as well as replacements with alternative schemes. All of them, because of the design processes that would have to be applied and the further delay, would have cost more. I assure the right hon. Gentleman that it is understood throughout the Environment Agency and my Department that every penny that we spend must be spent in the right way. We ensure that the budgets that we manage go as far as possible, and I will come on to explain why the spending must go ahead.

Given that something must be done, the Environment Agency has focused on identifying the cheapest and best way to solve the problem. It looked into the matter in considerable detail, and I have seen the summary of the detailed analysis, which points to the radial gate solution that the agency is pursuing. The other options would be more expensive, and in some cases there would be no guarantee that they would even work, because they are untried in other areas. Replacing the weir will not remove risks altogether, but it will reduce them to a reasonable level for the staff concerned and provide more reliable long-term protection for those living on the flood plain to the north.

When reviewing the background to the matter, I also considered the steps the Environment Agency has taken to consult local residents on the project. Objections have been raised, primarily from those who are not at risk of flooding, but who will suffer increased traffic and disruption during the work, and I entirely understand that.

[Nicola Blackwood]

That is not entirely accurate. I have received objections to the weir project from people who are at risk of flooding throughout my constituency and nearby constituencies.

[Richard Benyon]

I entirely accept that. I am talking about the local community, and the most vociferous objections are about disruption. I do not want to disrupt people’s lives more than we must. I am sure that my hon. Friend understands that I want to put on record that others are strongly supportive. Northmoor parish council has twice written to the Environment Agency urging it to proceed with the work as soon as possible.

Proposals to replace the five weirs have been considered by the Thames Regional Flood Defence Committee, and it has agreed to include them in the flood defence programme. That is important because the committee is made up of elected councillors from local authorities in the region. They provide a degree of local democratic input and accountability for decisions to allocate funding. They will not have taken the decision to allocate £2.5 million to Northmoor lightly, and they recognise other flood defence priorities in the region.

Over the past two years, the Environment Agency has consulted extensively with local residents and listened to their concerns about the scheme. I am sure that many would like to have had more, and I will take up the matter of the contractor, which causes me genuine concern. The agency has heard what people have been saying about the increased traffic south of the river and made substantial adjustments to the plans, at an additional cost of £100,000 to the project.

The work has the support of Northmoor parish council and the Thames Regional Flood Defence Committee. Despite limited national funds, the Environment Agency’s board has allocated funding to allow it to proceed. The chair of the Environment Agency wrote to me last week setting out the justification for the project. I have heard my hon. Friend’s points, and the views she expresses on behalf of her constituents. I have considerable sympathy but, as is common, there are two sides to the story. I am satisfied that this is a case not of health and safety gone mad, but of something needing to be done to solve a problem that perhaps should have been sorted out some time ago. I am sorry, but I do not take the view that, just because there has not been an accident, one may not occur.

I understand that there may be areas where consultation could have been improved. I will make every effort to ensure that the points that my hon. Friend raised are answered, and I will do so in a letter as we are running out of time. I assure her that I will continue to converse with her and do my best to minimise the impact on her constituents. I want to put it on the record that I fight to ensure that every penny of money that is spent on flood alleviation schemes is spent in the best way possible, and I hope that she will come to realise that the problem has been dealt with in the best possible way.

Question put and agreed to.
