Do you live in a flood risk area?

rsz_shutterstock_344300294Even if your home or business was left untouched by the most recent round of flooding to hit the country, you could still be at risk at some point in the future.

Floods can be caused by rivers or reservoirs bursting their banks, by sea surges, or by excessive ground and surface water. The Environment Agency categories areas as very low, low, medium and high risk. Very low risk areas have less than a 1 in 1,000 chance of flooding each year. In areas defined as low risk, the chance of flooding rises to a maximum of 1 in 100, or one per cent, each year.

The chance of a flood rises to as high as 1 in 30 in medium risk areas, while in high risk areas the chance of a flood is greater than 1 in 30. The calculations take into account any flood defences that may have been installed, as these reduce but do not completely eliminate the chance of a flood occurring.


When does flooding occur?

River flooding takes place when a river is unable to cope with the amount of water draining into it, which typically occurs when the level of rainfall is so heavy that the soil cannot soak it up. The more quickly the rainwater reaches the river channel, the more likely it is that a flood will occur.

The type of soil is another factor, and the presence of large numbers of trees and plants can dramatically reduce the likelihood of a flood. These remove water from the soil, increasing the amount of surface water that can be soaked up before flooding takes place.

In the event that you become the victim of a flood, removing the water as quickly as possible is essential. A Grundfos water pump will remove all the standing water from your home or premises so that the process of drying out can begin.


Where are the greatest flood risks?

According to the Flood Free Homes campaign, which comprises the National Flood Forum, Friends of the Earth and the Association of British Insurers, the parliamentary constituency of Boston and Skegness has the greatest flood risk in England and Wales. In any given year, around 7,500 homes here have a 1 in 75 chance of a flood.

For example, the Vale of Clwyd is a particularly high risk area in north-east Wales and the seaside town of Folkestone also has more than 7,000 homes at risk.

Due to its proximity to the River Thames, Windsor is also an area found to be at high risk of flooding. Leeds, which has been flooded a number of times, also makes the list, as does the Kent constituency of Canterbury. Other coastal areas at risk include Cleethorpes, Gainsborough, Kingston upon Hull, Sheppey on the east coast, Brigg and Goole, and Sittingbourne.


North Sea storms

The upper east coast of England has always been a flood risk area due to storms over the North Sea bringing huge waves and water surges onto the land. Other inland areas at risk include Oxford East, Huntingdon, Runnymede and Weybridge, and Spelthorne in Surrey.

If you live in an area of high flood risk and want to learn more about the benefits of owning a Grundfos water pump, take a look at our range of submersible pumps; alternatively, contact our friendly and knowledgeable sales team, which will be more than happy to advise you.

Remember; anyone living in England or Wales can use the Environment Agency website to enter their postcode and discover their level of flood risk. The information from the agency is also used by insurance companies, along with data from a wealth of other sources, to work out how much flood cover will cost in a particular area.
