This is what happens to London's sewers when fat and oil goes down the drain

Londoners are being urged to be vigilant about disposing of household waste this Christmas. 

Thames Water estimates that two Olympic swimming pools worth of cooking fat and grease will be poured down British sinks over the festive period, contributing to the 6.7 million homes blocked each year. 

The water provider says they see a a 25% increase in blockages at this time of year. 

It costs £12 million per year to clean sewers.
