Severn Trent Water in plea to keep Leicestershire's sewer fat-free
A water company is appealing to customers to help put sewers on a fat-free diet.
Severn Trent Water is asking householders not to pour fat down sinks and drains, to prevent a build up of the waste.
Spokesman Craig Bayliss said: "We continue to see an increase in fats in our sewers and at our treatment works."
He said liquid fat, oil and grease might not appear to be a problem when it was poured down a sink but when it hit the walls of the cool sewer pipe it stuck and hardened.

He said: "Over time, this will build up, causing blockages and potentially leading to overflows.
"The only way to rid the sewers of these fat blockages is to use a high-pressure jet to chisel the fat from the walls of the sewers or, in serious cases, to use heavy machinery.
"All of this work costs money, which is then passed on to our customers."
Severn Trent spends more than £10 million each year cleaning more than 700km of sewers, he said.
The company said fat and oil should be poured into a container and left to harden and then put in the kitchen bin.
