Growing risk of flash floods underestimated

According to a recent article in The Guardian, Flash flooding is a far greater threat to homes, railways and roads than river or coastal floods but is completely excluded from government plans to deal with increased rainfall.

The extent of the problem

The article identifies a growing risk of flood damage due to flash floods with:

  • • The risk of flash flooding rising, as climate change leads to more intense, more frequent rainstorms
  • • The Met Office showing that extremely wet days have become more common.
  • • The risk being confounded by Britain’s antiquated drainage and sewer networks and concreting over of land for development. The result of this being that the surface water can neither be absorbed or quickly drained away.


The evidence

  • • Flash flooding was the principal cause of the most damaging floods in UK history, which in 2007 caused over £3bn of damage, caused 13 deaths and was classified by the Environment Agency (EA) as a “national disaster”.
  • • In 2013, new maps from the EA showed 3m properties were at risk from flash flooding in England, (compared to 2m from river and coastal flooding).
  • • There are at least 20,000 sewer overflows a year in the UK.


Flood damage risk to transport networks

Risks to transport have also been identified: Network Rail is monitoring 200 “high risk” earthworks – embankments and cuttings vulnerable to washing away. In April the Guardian revealed that 57 tube stations are at high risk of flash flooding, including Manor House which flooded on Friday. The London Underground report said it was “only a matter of time” before serious flooding strikes.

“We know our major cities, including London, are vulnerable to surface water problems,” said Bob Ward, policy director at the Grantham Research Institute on Climate Change and the Environment at the London School of Economics. “But the UK remains at risk because the government refuses to confront the problem. The main problem is the inadequacy of the drainage system, which even nine years after the 2007 floods are still not up to the task.”

Dealing with flood damage

Most insurance claims made each year for flood damage are because of flash floods. In the event that you experience flood damage in the home, or at your business premises, your best course of action is to seek the advice of flood damage restoration experts, like Rainbow.

They will be able to return the property to its pre-incident condition as quickly as possible, minimising secondary damage, efficiently and effectively, with the minimum of disruption.

Flood clean up and flood damage restoration is a process that can have serious consequences for the structure and integrity of your property, if the operation is not handled by experts in flood damage management.
