Groundwater flooding threat remains high

Groundwater flooding threat remains high


The threat of groundwater flooding remains high around West Sussex despite the past few days sunny weather.

West Sussex County Council warns today although groundwater levels are falling the ground is still saturated after the wettest winter on record.

More unsettled weather has been forecast for next week. Unless a prolonged spell of dry weather occurs in the next few weeks, groundwater flooding continues to be a risk.

Groundwater flooding occurs when water rises up from an underlying water source. There is normally a delay when it emerges after rainfall – varying from a week to a month.

Villages susceptible to groundwater flooding in West Sussex experience a quicker rise in groundwater levels than other locations. Flooding will usually occur days or even weeks after heavy or prolonged rainfall, and can last several weeks.

Many traditional methods of flood protection, such as sandbags, may not be effective against flooding from groundwater. This is because water can come up through the floor and toilets, often leading to foul flooding (waters laced with sewage).

Those in flood risk areas should sign up to the Environment Agency’s free flood warning system by calling 0845 988 1188 or visiting the Environment Agency website.

Although the Environment Agency includes groundwater alerts in this service, there are isolated locations that are not covered. People in properties with a history of groundwater flooding should be vigilant and watch for signs of water infiltration in basements.

If you live in areas with high groundwater levels you should consider moving precious belongings out of cellars.

You can find advice on what to do before, during and after floods.
