A massive €670,000 is being spent per year by Dublin City Council (DCC) to clean up after illegal dumpers in the capital.
It is understood that the council employ nine staff on a full-time basis to oversee the clean-up.
These costs are broken down into labour and fuel.
The figures - largely the same in both 2014 and 2015 - were released after a question by Ballymun Councillor Noeleen Reilly. She thinks the new pay-by-weight waste scheme, set to be introduced by the Government, will lead to more illegal dumping in the city.
She said some families are being quoted 150pc price increases.
"I have no doubt we will see further increases in illegal dumping," she said.
Environment minister Simon Coveney is to meet waste companies next week over the increases.
Fianna Fail spokesman for Expenditure and Reform, Dara Calleary said that "the majority of people don't want to be in a situation where they are illegally dumping".
