WISE officers will support work being done by the council’s internal environmental crime enforcement team.
Liverpool City Council said it was not setting FPN targets because it preferred to focus on encouraging responsible behaviour.
Robertson-Collins said: “Our goal is to help promote positive behaviour and show people who don’t respect our city that it will not go unseen.”
Those caught littering face a £150 fine, while dog owners who do not clean up after their pets risk a £100 penalty.
A tiered penalty system has been introduced for fly-tipping, which starts at £500 and can rise depending upon the severity and scale of the offence.
WISE managing director John Dunne said he wanted to secure “long-term improvements in local environmental quality”.
He said officers would use body-worn cameras and mobile technology to verify offenders’ details.
