An estimated 30 tonnes of waste has been dumped on private land near Fulbourn, Cambridgeshire.
The Council believes fly tips of this size are likely to be commercial operations, with contractors who are hired to dispose of the rubbish instead dumping the load on private land.
It's the latest in a string of local fly-tipping offences.
Cllr Neil Gough, South Cambridgeshire District Council Lead Cabinet Member for Environmental Services, said: “The Council has recently improved the process in which it investigates and clears fly tips to ensure there is no delay in clearing up potentially harmful waste while investigations are carried out. But it is really concerning that our Environment Enforcement Officers have seen an increase in these apparent ‘industrial-scale’ occurrences.
