THE go-ahead for Labour's key plan to rid the borough of fly-tipping was given by the council's cabinet on Monday, with a promise that finance will be available to keep the campaign going.
The Don't Mess With Croydon: Take Pride campaign will cost £37,000 to implement but funding runs out in 100 days.
Councillor Phil Thomas, the shadow cabinet member for Clean Green Croydon, said: "This seems to be a gimmick just to please the press but there is only money to fund it for the first 100 days. In a full year the campaign will cost £1 million and we want to know where that money is coming from."
Cllr Thomas also complained there appeared to be no money to pay for extra enforcement officers to control fly-tipping or meet Labour promises to increase CCTV coverage of fly-tipping hot spots.
Councillor Stuart Collins, cabinet member for a Clean Green Croydon, described the attack on rubbish and fly-tipping as a huge task and said in the first 100 days that it was important that people saw improvements.
He said: "This is very much a rolling programme. Rest assured we are getting to where we want to be. We will make sure we fund the campaign so that at the end of four years, this borough is the cleanest in London."
Cllr Collins said the council, its staff, residents and businesses had a responsibility under the programme.
He said: "We want this to be a partnership between all of us to make our town clean and take care of it."
Cllr Collins said the campaign was based on three Es; education, enforcement and easy.
The aim would be to educate residents into knowing the full range of services available and encourage them to report fly-tipping offenders.
It would also be made clear the council would not hold back from prosecuting fly-tippers.
