Sewer flooding

Banner image

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:

  • Weather
    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.
