Surface water flooding

This is flooding caused by the existing drainage network being overloaded, either by heavy rain or by blockages in the system. This causes water to run across and create ponds on the land or roads. Maps showing areas that might be at risk of surface water flooding are available online.

It is very difficult to predict this type of flooding. The extent of the flooding depends on the duration and intensity of rainfall. Most of it is short-lived and is known as flash flooding.

Flooding can also occur when land is saturated and is not able to absorb any more rainfall.

Landowners are responsible for dealing with storm flood water on their land. Landowners must accept storm flood water run-off onto their land if it is due to the natural profile of any adjoining land. They may install measures to protect their land and property but must not divert storm flood water in such a way that it could cause flooding to adjoining land or property.

If flooding is affecting roads you can report this via our online form.

In an emergency situation, call 999.
