On Monday, we were treated to a very enjoyable assembly led by a Mad Scientist on behalf of Thames Water. The assembly focused on the growing problem of ‘FATBERGS’

Fatbergs form when people put things they shouldn’t down sinks and toilets, like wet wipes, cooking oil or nappies.

One of the biggest ever fatbergs was discovered in London in 2017. It was 250 metres long and weighed a huge 130 tonnes. That’s the same weight as 11 double-decker buses and the same length as two Wembley football pitches.

There are 300,000 sewer blockages each year, costing the country £100m to clear up, hence why Thames Water are so keen to pass the message on and how we can ensure it does not keep happening.

There is lots more information on the CBBC newsround page.
