GROUNDWATER FLOODING

Groundwater flooding happens when levels of water in the ground rise above the surface. It can affect property and structures above and below the ground.

It is most likely to happen in areas where the ground contains aquifers. These are permeable rocks that water can soak into or pass through.

The Environment Agency is responsible for managing the flood risk from main rivers, estuaries and the sea. Main rivers are normally large river channels.

County and unitary authorities have been given the role as Lead Local Flood Authorities to manage local flood risk including surface water, groundwater, and rivers or streams that are not main rivers.

In some areas the Environment Agency provide flood alerts for flooding from groundwater.
