Would it not be easier to find these items in smaller sewers before they get
to the really big ones, Certainly they would have a lot of smaller call
outs, but one supposes these should take very little time to clear and not
gum up the whole of a major sewer affecting thousands of people. Wet wipes
are apparently making things worse at the moment. Maybe nappies and wet
wipes which are bio degradable might well help.

"Engineers are working around the clock to clear a "monster" 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.

And it would help if people didn't flush things like nappies down the
toilet. Instead of smart water supply meters, maybe we need smart loo
flush meters. If you send something down that you shouldn't, you pay.
