Fifteen tonnes of waste fat, grease and sanitary products, which had formed the largest ‘fatberg’ ever found in the UK, has been removed from a London sewer.
According to Thames Water, it first became aware of the bus-sized lump of wrongly-flushed festering food waste when residents in nearby flats complained that they couldn’t flush their toilets.
CCTV investigations at the site in London Road, Kingston found the mound of fat had reduced the 70x48cm sewer to just 5% of its normal capacity.
“Given we’ve got the biggest sewers [in the UK] and this is the biggest fatberg we’ve encountered, we reckon it has to be the biggest such berg in British history,” commented Gordon Hailwood, waste contracts supervisor for Thames Water.
“The sewer was almost completely clogged with over 15 tonnes of fat. If we hadn’t discovered it in time, raw sewage could have started spurting out of manholes across the whole of Kingston,” he continued.
Hailwood added that the berg was so big that damaged the sewer itself.
As a result company said that it has begun repairs to 20 metres of damaged pipe, but that work expected to take up to six weeks to complete.
Managing fatty wastes
Once operational Thames Water has committed to provide at least half of the fuel the generator requires to run - in the form of 30 tonnes a day of fat, oil and grease ('FOG') - enough to fill a six metre long shipping container - that would otherwise clog up London’s sewers. (See WMW Story)
“Homes and businesses need to change their ways,” concluded Hailwood. “When it comes to fat and wipes, please remember: ‘Bin it - don’t block it.’”
