Sewer pipe responsibility

There are two main types of sewers – private and public. Private sewers are the responsibility of you, the customer. While public sewers belong to us, the water company, so are our responsibility. In addition, there are highway drains and gullies that are the responsibility of local authorities.

Responsibility for highway drains

We are not responsible for blocked highway drains. You should report blocked highway drains to the relevant local authority - usually your county council. They are responsible for keeping road gullies clear so that water can drain away freely. If a gully becomes blocked and causes flooding in the road, the Highways Authority will be responsible for clearing it. 

We are partly responsible for highway drainage, which is why you'll see a highway drainage charge on your bill. If too much water enters our sewers and drains, and that casues them to overflow, we are responsible.


Is one of our sewers blocked? Let us know immediately.
