The bulk of the work is being performed in the heart of London - underneath Leicester Square.
The "flushers", as the workers on the site are referred to, are set to remove one million kilograms of fat from the sewer. According to the Independent:
The cleanup is expected to continue for a couple of weeks. [Via The Independent]The operation, which began in the early hours of this morning, is claimed to be the largest-ever sewer clean-up of its kind.The build-up is the result of years of "sewer abuse" - when anything other than water, human waste and toilet paper is put down drains - according to Thames Water.Danny Brackley, the water company's sewer flusher, said: "We're used to getting our hands dirty, but nothing on this scale."We couldn't even access the sewer as it was blocked by a four-foot wall of solid fat."
