fatberg example

• 10 tonne fatberg of fat and wipes was removed from a london sewer
• the toxic lump of congealed fat and household waste was40 metres long and so heavy that it broke the 1940s era sewer
• repairing the damaged sewer cost £400,000 and took over two months
• fatbergs form together when fat clumps together with other household waste and are becoming an increasing problem in london and 32-34 million litres of cooking oil are used every year and most is poured down the drain
• the use of wet wipes and toilet paper is also increasing which is exacerbating the situation
• in 2013 a fatberg weighing 15 tonnes was found in Kinsgston and last year workers spent 4 days clearing an 80m long fatberg from underneath Sheperds Bush Road
