Sewer flooding can also happen for a number of reasons beyond our control
Pipes can become blocked, especially when people put things like cooking fats, wipes and other items down the drain when they should be placed in the bin.
Extreme weather, including periods of intense rainfall, prolonged periods of rain or snow melt, can sometimes overwhelm sewers, as they are unable to carry the extra water away quickly enough.
At times of flood, river banks may burst, rising river levels can stop sewer outflows from working properly and flood water can get into the sewers from other sources.
All of this can push sewage back up the pipes and cause them to surcharge. In these circumstances we are not liable for any problems caused by the flooding, though we can offer some limited help to clean-up.
