Managing Flood Risk

Robin Walker Excerpts

Monday 3rd March 2014 Commons Chamber

[Caroline Nokes (Romsey and Southampton North) (Con)]

The issue of managing flood risk has inevitably come to the fore in my constituency. Since 24 December, some properties have been flooded not only by river water but by foul sewage. Environment Agency records show that back in 2007, Romsey, along with Winchester, was identified as one of the areas in Hampshire that were most prone to flooding.

I want to touch on some specific issues, including development, which other Members have already mentioned. We should think about development not just on the floodplains, but in the catchment areas. We should think about the impact of building yet more houses on land that has previously acted as a natural sponge. We should think about the run-off caused by more tarmac and more roof tiles.

In my constituency, during the run-up to Christmas and into the new year, significant problems were caused by surface water run-off and combined drainage systems that simply could not cope with the amount of rainfall. Since then, however, the problems have been caused not by foul drainage but by the beautiful River Test, which has burst its banks in several places, and by its carriers and tributaries. That has had an impact in many parts of my constituency, not just in Romsey.

I agree with other Members who have said that we need a coherent strategy. We cannot view Romsey in isolation from the villages further north along the river valley, because any work that is done further north will have an impact on Romsey. In the villages, I have heard many calls for dredging, for a widening of the streams and watercourses, and for better weed clearance. However, that could have the effect of sending water down to Romsey and the River Test even faster. We know that the Test has a maximum capacity of about 50 tonnes of water per second, but according to some figures it has run at 55 tonnes per second over the past few weeks. It does not take a rocket scientist to work out what will happen next: the river will flood. We need a coherent strategy that will establish ways of slowing the river down as it passes down the beautiful Test valley.

I am not an engineer and I do not pretend to have the solutions, but I think that we can work something out. Just over a week ago, I was told by the Army that it was necessary to find bits of land that could be flooded safely without affecting people’s homes and without necessarily affecting sites of special scientific interest, in a manner designed by the Environment Agency. The water needs to be slowed somewhat, so that when it arrives at Romsey—where all of it has to pass under one bridge at Mainstone—there is not a deluge but a controlled flow.

It is vital for us to use the knowledge we have gained over the past month or so. The help from the military has been invaluable, but I also pay tribute to the Environment Agency, many of whose staff have been working 24/7, literally around the clock, putting in more than 80 hours per week just to ensure that homes are kept safe and people are not flooded out. We have learnt a great deal. Aerial photographs taken in my constituency show exactly where the Test has flooded. A massive amount of work has also been done on a little-known river, the Fishlake stream. I do not think that anyone knew quite how fragile the bank of that stream was until the Friday at the beginning of February when the water started to overtop the bank and erode the outside of it. Suddenly, it became a crisis point. I do not believe that the Environment Agency identified it as such back in 2007, but we have learnt this time. We have had thousands of man hours of assistance—engineers have tried to establish the best way of preserving and protecting the bank for the future—and we have had critical lessons to learn.

I should pay tribute to a host of organisations in addition to the Environment Agency, particularly the emergency services, but also the Houghton fishing club, a wonderful riparian owner in the north of the constituency. Its members were out digging relief channels and making sure that houses in Stockbridge were protected during the critical first weekend of the flooding. There has been flooding in Stockbridge, but it has been limited to three houses. Stockbridge is a beautiful village on the banks of the Test, and many carriers run under the high street. It is phenomenal that only three houses were flooded; the situation could have been much worse had it not been for the immediate response of the fishing club, which, as an organisation that has existed for many years, knows the river better than almost any other. It was able to identify what could safely be done to create relief for the properties on the banks of some of the carriers that were in the most peril, without endangering further houses.

I also pay tribute to all those who have been involved in the multi-agency approach, and to the independent companies that have made fantastic offers of help with the flood effort. I am thinking particularly of NGS, a company in Southampton that is best known for supplying grit and salt for roads in icy weather. It donated sand for sandbags at a critical time, just as Romsey had established that an additional 40,000 sandbags were needed. I gather that about 80,000 sandbags have now been laid down in the affected part of the borough, thanks to a phenomenal effort. Travelling around the constituency over the weekend, I saw areas where the provision of sandbags was still essential.

On the banks of the Test, the groundwater-fed river is causing a considerable problem. Water levels are still rising, and groundwater springs are still popping up in places where they have never appeared in the past. The village of King’s Somborne, for example, has a wonderful stream passing through it, but that stream is overflowing into many houses across roads, and has made it incredibly difficult for people to get out just in order to buy essentials. Many businesses such as village pubs and shops, which are critical to village life, are unable to trade, having found themselves under several inches or even feet of water.

I echo the call made by my hon. Friend the Member for Beverley and Holderness (Mr Stuart). Businesses need to know how to apply for funds: they need the forms. I know that Test Valley borough council has done great work in putting information on its website, but when the applications are made, it will be imperative for funds to arrive, and to arrive quickly.

[Mr Robin Walker (Worcester) (Con)]

My hon. Friend is making an excellent speech. Does she agree that, as well as the businesses that she has mentioned—which, of course, need all the help we can give them—there are businesses that have been cut off and very badly affected by flooding, although they may not have had floodwater inside their premises? I welcome the £10 million that the Government have already set aside to help those businesses, but does my hon. Friend agree that even more may be needed?

[Caroline Nokes]

My hon. Friend is absolutely right. There is an industrial estate in Budds lane in my constituency. Budds lane was horrendously flooded. The emergency services had to shut the Greatbridge road because of the depth of water, yet some businesses in the industrial estate were dry. There was no access to them, however, so there was no passing trade, and they could not get their staff into work, but the business itself was not affected by floodwater.

I want to conclude with a plea. Almost inevitably, it comes from the lead flood authority, Hampshire flood authority, and it refers specifically to the flood defence grant in aid. The deadline for the submission to Government is incredibly tight. It was moved from 3 March out to 12 March, but that is only next week, and there are concerns that what will happen as a result is that the most developed and worked-up schemes will be submitted, which might not necessarily be the schemes that would best protect the villages in my constituency or Romsey itself. That is a very real concern, because what we have learned over the past three and a half weeks is where the crisis points are. We perhaps did not know in detail where they were previously, but we do now. It is absolutely critical that the areas which need the help most, in that they need the most investment to prevent future flooding, are the ones that get it. We need to have not simply the schemes that are furthest down the pipeline, but the ones that address where there is the biggest point of crisis.
