"Engineers are working around the clock to clear a €œmonster€� fatberg 1km long which is clogging a sewer in Birmingham.

The blockage is not expected to be removed until June, water services company Severn Trent said in a statement, adding that the fatberg was about four miles east of the city centre, in Hodge Hill.

The mass is thought to weigh about 300 tonnes €“ equivalent to 250 cars. The water services company was alerted to the stoppage after its sensors detected rising water levels in the sewer."

Written as adulation of their sensors.

But just how sensitive do they need to be? Could they not have been triggered when it was only 999 metres long and 299 tonnes/249 cars?

It is a 300 tonne fail. They need to detect before the fatbergs get so immense - however they do it.

Many of the Fatbergs come from Takeaways / restaurants running without
