‘Concreteberg’ weighing 105 tonnes found in London sewer
Authorities say 100-metre-long mass is the result of concrete being poured down drain
People pouring concrete into sewers has led to a “concreteberg” forming in central London that weighs 105 tonnes, as heavy as a blue whale.
The 100-metre-long mass is blocking three Victorian-era sewers in the heart of the capital. Thames Water’s operations manager, Alex Saunders, said it was the largest mass of concrete the company had seen, and could take two months to remove at a cost of at least several hundred thousand pounds.
