Flooding

Romsey is located on the banks of the River Test, a world-renowned chalk stream. Too many times in the past few months the river has been an unwelcome visitor in too many people’s homes. Our problem is not just the river, which is ground fed, but the springs that have popped up in many places; the ingress of groundwater into the foul drainage systems, causing the drains to fail and rivers of sewage to flow through the streets of villages like Chilbolton and Longparish; and surface water flooding, which we experienced in Romsey from Christmas eve until well into the new year. For householders along the Causeway in Romsey, there have been weeks of misery: homes being permanently pumped out, an access road undermined by the sheer weight of water, and the fear that access to the crucial pumping station for the town would not be maintained.

The situation has not all been negative, however. There have been phenomenal examples of community spirit and pulling together in a crisis. I have praised them before, but I will do so again: Romsey’s amazing retained firefighters gave up much of their Christmas and were among the first to be out there again when the February floods hit. They were indefatigably cheerful, even when their road closures signs were ignored and damaged. The Army and the Navy arrived in Romsey the week before last and designed the most amazing device—colloquially known as the “cat flap”—to divert water from Fishlake stream back into the main body of the River Test, and to lay 40,000 sandbags at strategic points around the town. They worked seamlessly with the borough and county councils, the Environment Agency and the emergency services, and were greeted with relief wherever they went.

However much I wax lyrical on how things were pulled together to aid Romsey and the surrounding villages in their hour of need, there are crucial lessons that we must learn. Little was known about the bank of the Fishlake stream until it was at crisis point, so work to identify at-risk areas has to happen and it has to happen now. There are some great local examples across Hampshire of communities with flood action plans and flood wardens where greater damage was averted. We now have to replicate that work everywhere.

People have spoken at length of the dangers of building on floodplains, and I agree. However, in many instances the houses are already there, so although we must avoid adding to that housing stock, we simply cannot abandon the houses already there. Protection is needed, and although I do not pretend to be an engineer or a drainage expert, when the water has subsided, we must work out what can best be done to avoid this happening again. Sadly, in many parts of my constituency the water is still rising, particularly the groundwater, unlike around the River Itchen where the water levels are falling.

When it comes to planning, we have to look at the existing infrastructure and the impact on surface water drainage from having additional roof tiles in previously open green spaces that acted as natural sponges to rainfall. I echo the comments of my hon. Friend the Member for Tewkesbury (Mr Robertson), who is no longer in his place, but we cannot look just at floodplains. We have to look at the catchment areas, which can also make a contribution. Where there has been development at Abbotswood on the edge of Romsey—a significant distance and uphill from the natural floodplain—there is a clear problem with surface water drainage flooding existing properties that are further down the hill. Over Christmas and new year there were huge problems in Winchester road in Romsey, with a combined drainage system simply overwhelmed by the amount of water, causing foul drainage flooding of homes. That might be regarded as totally separate to the subsequent flooding caused by the River Test, but the misery for residents is no less.

I spent last Saturday morning looking at the defences that the military and the Environment Agency have put in place to prevent further flooding in Romsey from the fragile bank of the Fishlake stream. I would like to put on record my thanks to Lieutenant Colonel Fossey and his team, who worked phenomenally hard to protect the town from further flooding. As one would expect, conversation inevitably turned to the future and what needs to be done to safeguard Romsey in the long term. I am the first to say that now is not the time for a knee-jerk reaction when deciding what would be best. The local authorities and the Environment Agency need to assemble experts and decide, not at a time of crisis but when the waters have abated somewhat, and they need reasonable time scales in which to do it.

There are certainly some thoughts already on whether land needs to be found that can be safely flooded without damage to housing. Attention needs to be turned to development and where new houses can best be placed away from floodplains in a way that will not impact on already creaking infrastructure. If necessary, we need to revisit housing numbers and perhaps take a view that some areas simply cannot accommodate more building. The water courses and drainage systems further up the Test valley from Romsey also need to be considered. I do not know whether extra capacity or deepening and widening the stream through King’s Somborne or the Wallop brook would help. Presumably that would run the risk of sending water further downstream to Romsey even faster and exacerbating the problems there.

Longparish, Chilbolton and King’s Somborne have all had 24/7 tankering operations to clear surface water from the drainage system, but it is a drop in the ocean. There are still people in Longparish and Chilbolton who cannot flush their loos, have a shower or wash their clothes, and this is Hampshire in the 21st century. I appreciate that the solution will be expensive and require careful planning, but if we are to experience longer, wetter winters in future and if this year is just a taste of what is to come, we have no choice.
