Sewage flooding is rare but when it does occur it can have devastating effects. Therefore, tackling it remains one of our key objectives.
Most flooding incidents occur due to blockages caused by inappropriate items being either flushed down the toilet (such as wet wipes) or poured down the sink (such as fats, oils and grease).
We have been working hard to improve how we monitor and maintain our sewers, while also helping customers avoid blockages by raising awareness about the impact of sewer misuse.
Identifying blockages on our network
In 2020, we trialled StormHarvester's Intelligent Sewer Suite at our Bath catchment to see if it could accurately predict potential sewer blockages as they begin to form.
During the trial, the machine learning technology detected more than 60 blockage formations in real-time, with a 92% accuracy in identifying early forming blockages.
Following the success of the trial, we are expanding the use of this artificial intelligence (AI) so it will cover all of our critical storm overflow monitors by 2024.
We are the first company in the world to commit to using AI technology across an entire sewer network to detect blockages, which will help us to prevent pollution and sewer
