Flooding can happen anywhere in Surrey, whether near to watercourses or not. Floods can even occur during summer months when thunderstorms trigger torrential downpours.
The drainage system sometimes can't cope with the magnitude of water that collects on surrounding surfaces, especially when they are already saturated with large quantities of water. In this case, even a small amount of additional rainfall can cause flooding.
Flooding can be caused by cracks in broken pipes owned by water companies and heavier than normal rainfall that causes water to run onto roads from fields and over-full rivers. It can also be caused by the collection of mud, leaves and other debris that block drains.
If you see a flood, you can report it on our on-line reporting form
If you think that the flood may be an emergency situation, please call 0300 200 1003 immediately instead of filling in the reporting form.
We are looking to gather as much information as possible from the public on historic flooding, to assist in assessing future flood risk and help with the development of Flood Risk Management Plans. If you have any information on past floods that you would like to share, you can report it using our online survey here.
