Fighting the Fatbergs one nudge at a time

Hearts & Science

Client: Thames Water

Fatbergs pose a real, long-term challenge for Thames Water. Incorrect waste disposal, where toilets and sinks were used in place of bins and skips, caused 75,000 blockages in 2018 and was an £18m headache for the business.

Over the past 2 years, Thames Water have been working to bring about behaviour change in their customer base, bringing the reality of Fatbergs to their doors. Midway through the campaign we were then hit with a national lockdown bringing an increase in time spent at home and the use of panic bought unflushable alternatives to loo roll. Despite this, the long term strategy has seen a 29% YoY reduction in blockages and last year contributed to 1,456 fewer blockages year on year.
