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. Find out more about surface water drainage charges.
If rainwater does not drain from your property into a public sewer, because you have a soakaway or similar, you may be entitled to a surface water drainage rebate.
