Massive lump of fat blocks sewer
A lump of fat the size of a double deck bus has been found clogging a London sewer.
Dubbed the Fatberg, it is made up of 15 tonnes of festering food mixed with wet wipes amongst other items and was discovered blocking pipes under Kingston in south London.
It has caused sewage flows through the pipes to be restricted to just 5% of normal and was created by people pouring cooking oils down the drain and flushing sanitary products.
The blockage was so critical it threatened to blast untreated sewage through manhole covers onto the streets of one of the leafiest London boroughs. The engineers who found it said they had never seen anything like it before.
Workmen spent 10 nights using high-pressure water jets to blast away the fatberg.
