Oldham Council is installing barriers at five sites in the borough in a bid to make it harder for fly-tippers to dump their rubbish.
When locked in place the steel structures do not allow vehicles to access the sites, which have all been identified as hot-spot locations.
One of the barriers has been put in place close to the entrance to Oldham Edge.
Councillor Arooj Shah, Leader of Oldham Council, said: “We know residents are sick to the back teeth of fly tipping – and so are we.
“That’s why we have made cleaning up the borough one of our priorities.
“But we can’t do it alone. We need people to work with us, look after their communities and call out those who are using the borough as a dumping ground.
Councillor Amanda Chadderton, Deputy Leader of Oldham Council and Cabinet Member for Neighbourhoods, said: “The barriers are one of the measures we are introducing as part of the council’s investment to clean up our streets.
“Unfortunately fly-tipping is an issue right across the country, not just here in Oldham. It’s not going away.
“But the idiots who dump waste at our beauty spots, streets and open spaces need to know we’ll continue to take action against them.”
As well as Oldham Edge barriers are also being installed at Rose Hey Lane and Propps Hall Road, both Failsworth; St James Street, Derker; and Hill Farm Close, Medlock Vale.
The barriers aim to stop vehicular access, but pedestrians will still be able to get through.
