Commons ChamberI congratulate my hon. Friend the Member for Spelthorne (Kwasi Kwarteng) on securing this debate. Sadly, it is an issue that we have had to discuss in relation to several areas, given the severity of the recent floods. I shall begin by setting some of these events in context and then turn to the more local impacts in his constituency.
First, I should like to place on record once again my thanks to the many people who worked tirelessly in response to the recent flooding events, including the staff of the fire, ambulance, police and other rescue services, local authorities, the Environment Agency, the voluntary sector, and local communities who helped friends, neighbours and families in difficult circumstances.
Unprecedented weather events caused the flooding that we witnessed across the UK. We experienced an extraordinary period of very unsettled weather from early December, with flooding on the east coast and around to Wales, and then many weather fronts coming in from the west and causing flooding across the country in various river systems and in groundwater. It was the wettest January since 1766 for England and Wales. Central and south-east England received over 250% of average rainfall. Met Office statistics suggest that for south England this was one of the most exceptional periods for winter rainfall in at least 248 years.
In addition, tidal surges caused by low pressure, strong winds and high tides led to record sea levels along many parts of the east coast. High spring tides brought coastal flooding to parts of the south and west coasts. River, surface water and groundwater flooding occurred in many areas. Towards March, flooding was mostly confined to the Thames valley, Wiltshire and the Somerset levels, the latter in particular seeing unprecedented water levels, while groundwater levels remained high across many southern counties.
Recent events impacted on the homes, businesses and farms of people across the country. Latest estimates suggest that over 7,000 properties have been flooded in England since the beginning of December 2013. This includes 2,316 properties since the most recent flood event began in early February. In addition, more than 48,000 hectares of farmland is thought to have been affected. There was significant damage to sea and flood defences and transport infrastructure in some areas. Urgent work is under way to repair the damage to rail links, with many lines back to full operation by 3 March. The House is aware that the extreme weather also affected power supplies to homes. It is estimated that power supplies to more than a million customers were restored over the course of the disruption. I am pleased to note that power supplies disrupted as a result of the high winds were also restored to all customers.
The Environment Agency is aware that the river system in the Staines-upon-Thames area is complex and consists of various connected channels which drain into the Thames, as my hon. Friend set out. All these rivers, at some point, cross the Thames Water aqueduct. As levels on the River Thames were so high, these rivers were not able to discharge into it as they normally would, causing them to back up and spill into the aqueduct at various points. Following months of persistent rain, there were also high groundwater levels so water could not drain away. Initial reviews indicate that it was a combination of saturated ground, high rainfall and high levels on the River Thames causing its tributaries to back up that caused the flooding experienced in the Staines-upon-Thames area.
The response was a magnificent effort. In the face of such unprecedented weather, countless people and organisations worked together round the clock to help those affected. The level of response, and the spirit of it, was staggering. I appreciate how hard everyone has worked and just how hard it is for those people whose homes and businesses have been affected. All levels of Government and the emergency services were fully engaged in dealing with the floods and extreme weather. The Government’s response was led by the Cobra emergencies committee. Through these meetings, we were able to ensure that all relevant agencies, organisations and local authorities were fully prepared and were doing everything possible to support households that had been affected. We ensured that local emergency plans and out-of-hours help were in place to give immediate assistance, wherever necessary.
The Environment Agency was at the forefront of the local response. In Somerset, for example, this included one of the biggest pumping operations the country has ever seen. Military personnel from the Royal Navy, Royal Marines, the Army and the Royal Air Force provided flood relief in affected parts of the UK. More than 5,000 personnel were committed to help with flood relief operations. Thousands more troops remained available if required. At a local level, tactical co-ordinating briefs took place for the local responders in areas at risk.
My hon. Friend raised a number of issues in relation to the water infrastructure in his constituency. I pay tribute to him for the way that he set out his position, not seeking to apportion blame, but in the spirit of seeking to learn from what happened to ensure that similar events are not repeated if, heaven forbid, similar extreme weather events occur in the near future or in the medium term.
As my hon. Friend pointed out, the residents’ relationship with the river is usually harmonious. It is part of the culture of the area and what makes it special, but when things change, impacts can be great and severe. He referred in particular to the operation of the sluice gate on the aqueduct. During discussions with those involved prior to the debate I sought to cover a range of options that I thought my hon. Friend might raise, such as the future safety of the area through the lower Thames flood relief scheme, which is being brought forward and developed, which I welcome. We touched briefly on the operation of the sluice gate. It is important to point out that the aqueduct operates as a mechanism for the supply of water into reservoirs, which then feed into the wider water system, so it is not meant to operate as a flood defence. However, it can be used to divert river water, and as my hon. Friend said, pumping enables that to happen, keeping water away from communities that are under threat.
Clearly, the operation of the sluice is an important part of the response when river levels and the level of water in the aqueduct are high, so we need to look at what happened in this instance. If local lessons can be drawn from it, I am keen to hear more about that. Having heard my hon. Friend’s contentions and the concerns that he has raised on behalf of his constituents, I am happy to raise some of those specific points with the agencies involved. I know that my hon. Friend will be doing that locally, but I am happy to support him in seeking the answers that his constituents understandably want in response to their queries.
My hon. Friend mentioned the issue of evacuation, and it is important to point out that it is a proposal of last resort. If people are at risk, people come first. We seek to protect property, but if people are at threat of injury, we need to remove them safely from the situation. That was repeated around the coast, for example, during the extreme weather conditions. Sometimes it is difficult to convince people that the threat is immediate, so it is a tough call for people to make locally, but it is important that we have that as a last resort. However, before that, as my hon. Friend pointed out, it is far preferable to ensure that the infrastructure is working as effectively as possible to make sure that that is unnecessary.
My hon. Friend also referred to the situation with regard to sewage, and a number of other hon. Members have raised that in recent debates since the flooding events. Flood water contaminated with sewage is incredibly unpleasant. Systems should be in place to cope with the normal flow of sewage, and they are. We have a resilient system, but the sewerage system is not designed to cope with extreme events and large amounts of water. It would be possible, in theory, to design sewers that were able to cope with much higher volumes of water, but as my hon. Friend pointed out, a large cost would be attached to that. In all these matters we need a balanced approach between what is deliverable and what is achievable. Ultimately, the investment cost has to be funded through the privatised water industry, as my hon. Friend set out, where bill-payers foot the cost. With regard to problems of sewage contamination, as with the operation of the sluice gate, if there are specific local instances where infrastructure was not up to the task, we can learn from that, and I can raise those issues with the water company.
We have recently seen the passage of the Water Bill, which has yet to receive Royal Assent, in which the Government set out their desire to see resilience at the heart of the industry—that is, resilience in terms of water supply, making sure that we have enough water to deliver the growth that we want, and resilience to climate change and to ensure that we have that great environmental quality in our water bodies around the country. Resilience could also be considered in terms of response to extreme events, so the regulator will now have to take that into account far more, as it has a primary duty of resilience.
I thank my hon. Friend for raising these issues. I would be happy to take forward the points on the local circumstances that he raised, perhaps by correspondence, to make sure that he and his constituents get the answers that they seek.
Question put and agreed to.
