We call this surface water and Anglian Water include the cost of removing it in their sewerage charges.
There are some properties where surface water does not drain to the public sewer. If you think this applies to your property and no surface water drains to or makes use of the public sewer you may be able to claim a discount, visit the Anglian Water website to find out how you can claim.
Important: if surface water (such as rainwater) from any part of your property drains to a public sewer you will have to pay a charge for this service.
