A 330-ton fatberg is clogging an English city's sewer, and it won't move for weeks

A massive fatberg, weighing more than 300 tons, is clogging a sewer in an English city -- and authorities say it is unlikely to move for weeks.

The mammoth mass of waste stretches to more than half a mile in length and weighs 330 tons, Seven Trent Water said in a statement. They estimated that the fatberg may not be cleared until June.
