We’re aware of the distress that sewer flooding can cause and we work hard to prevent flooding from our sewers.
What causes sewer flooding?
There are lots of possible causes of flooding in your home, the most common are:
When we have exceptional weather with intense or long periods of rainfall, the sewers can become overwhelmed and aren’t able to carry the additional water away quickly enough.
- Blocked pipes
Pipes can block with fatty build ups, root growth and non-flushable objects like wet wipes.
Who is responsible?
The table below shows who is responsible and contact details for each type of flooding:

Local authority map
If you are experiencing flooding which you believe has occurred from the highway, you can use the map to contact your local authority about the flooding.
We’re responsible for clearing any blockages from the pipes highlighted in brown below. The pipes marked in blue are the responsibility of the homeowner.
You may find that a shared sewer pipe that you share with your neighbours runs through your land. In this case it would be classed as a public sewer/lateral drain and would be our responsibility.
