Surface water drainage

Surface water drainage occurs when rainwater falls on a property and drains away.

Most rainwater falling on properties drains into public sewers owned by the ten water and sewerage companies in England and Wales. The companies are responsible for removing and processing this rainwater. It costs about £600 million a year to provide this service.  If rainwater drains from your property into a public sewer, you will be charged for surface water drainage through your sewerage bill.
