Giant fatberg clogs up a sewer
A giant 3ft deposit of fat has been found clogging up a city's sewer.
Staff from utility firm Dwr Cymru Welsh Water found the "fatberg" while attempting to clear a blockage under Mill Lane in Cardiff.
Officials say they believe the obstruction was caused by a mixture of cooking fats and oils - made worse by wipes and other sanitary products collecting behind it.
Dwr Cymru Welsh Water, which is running a new campaign called Let's Stop The Block, said blocked sewers were causing major problems and cost more than £7 million a year to clear.
The not-for-profit firm's director of waste water services Steve Wilson said: "Most of the blockages we deal with are caused by everyday items put down the toilet, such as wipes, sanitary towels, cotton buds and dental floss, as well as fat, oil and grease that people have put down their drains.
"It doesn't take much for any of these to cause flooding to a home.
"A lot of people aren't even aware that these items can cause sewer flooding and pollution in their homes and communities.
"With the collective support of enough people, we will be able to reduce the blockages, floods and pollution that cause so much distress.
"Reducing these blockages will also mean that our not-for-profit company will also be able to invest more in other improvements on behalf of our customers."
