Flooding

With much of North Somerset situated in low lying areas and climate change expected to increase the intensity and frequency of rainfall events, flooding is a real risk for our area which can put lives in danger and can potentially cause expensive damage to homes, businesses and infrastructure.

Reporting a flood

  • burst water main
    To report a burst water main visit the Bristol Water website.
  • blocked or defective sewer
    To report a flooding incident caused by a blocked or defective sewer visit the Wessex Water website.
  • current flood incidents
    If you notice or are affected by localised flooding, report a flood online.
  • post-flood incidents
    If you've previously been affected by a flooding issue you can let us know by using our flood report form (doc).

What to do during a flood

Download our flooding factsheet (pdf) for information about what to do during a flood, and contact details for organisations that may be able to help if you are affected by flooding. 

Managing flood risk

As the Lead Local Flood Authority in North Somerset we are responsible for managing flood risk from sources such as surface runoff, groundwater and ordinary watercourses. For more information about our responsibilities to manage flood risk and the actions we're taking - including details about our local flood risk management strrategy - read our managing flood risk FAQs.

Flood risk planning, development and drainage

We recognise the importance of considering flooding issues when sites for new property are developed and designing drainage systems to minimise the effect of any additional surface water. For more information read our flood risk planning, development and drainage FAQs.

Gullies, ditches and drainage

We don't empty gullies on private land, but regularly empty and clean gullies and their connections to the drainage system along the highway network and aim to carry out essential works within 24 hours. Although most ditches in the district are on private land and the responsibility of the landowner, we will investigate concerns about them, as well as maintaining any ditches on public land. The larger open ditches are under the control of the West Mendip Internal Drainage Board and North Somerset Internal Drainage Board.

Land drainage consents

We are responsible for land drainage consents (sometimes called flood defence consents) for ordinary watercourses. It is essential that anyone who intends carrying out works in, over, under or near a watercourse or flood defence contacts us to obtain any necessary consents before starting work. Find out more in our land drainage consents FAQs.
