What causes flooding?
Surface water flooding is caused by the run-off of water from land, property or highway during heavy rain, or occasionally by public sewers or drains overflowing when they are overwhelmed by very heavy rainfall.
Areas potentially at risk from surface water flooding are shown on the Environment Agency map.
You can read our flood risk management report here.
How to report it
We are responsible for managing the risk of surface water flooding and flooding from minor watercourses. The duties include:
- investigating where land that is not normally covered in water becomes covered in water (including any significant flood incidents caused by rainfall)
- to implement land use planning and work with communities to avoid inappropriate development in areas of flood risk
- to warn and advise the public during emergencies and manage flood recovery
- to provide and manage highway drainage and roadside ditches
If you want to undertake any works in a watercourse, or are aware of such works being undertaken, please check our guidance on Land Drainage Consent.
How to report other flooding
