Oral question asked in the House of Commons, by Martin Salter (Labour). It was answered on Thursday, 25 October 2007 on behalf of the Department for Environment, Food and Rural Affairs.

Flood Risk

Question: In addition to welcoming the sensible suggestions made by my hon. Friend the Member for Stafford (Mr. Kidney) about managing river valleys so that their uplands are not intensively farmed or left in a situation where flood water can rush down them, will the Secretary of State consider earmarking some of the welcome investment in flood relief and flood defence schemes for the overhauling of antiquated surface water drainage systems? They are not up to the job, and caused as many problems as flooding from river valleys itself.

Answer: Now that I have announced the phasing of the increase in funding over the next three years, the Environment Agency will be in a position to plan. It will need to talk to local authorities about surface water drainage. The truth about such drainage is that we have a system that was built between 100 and 150 years ago, at a time when people did not expect to have to cope with the amounts of water that we have recently seen. The second problem is that we have concreted, covered with tarmac and paved over a lot of the surface land in our towns and cities, so when it rains to such an extent, there are fewer places for the water to go. It is not soaked up by the ground that is already saturated. Those are some of the lessons we have to learn. It will be a combination of improving capacity and ensuring that new drainage is built to a higher specification than was the case in the past, but we need to ask what more we can do in towns and cities to improve capacity to enable water to run off when we have rain of that sort.
