Sutton Council said it had served a planning enforcement notice on the landowner, requiring them to clear the remaining fly-tipped waste from the site and restore the land to its former natural state.
A spokesperson said: “The council will continue to make clear to the landowner what their legal responsibilities are.
“If they fail to comply with the planning enforcement notice, the council will take the next steps in this legal process once the compliance period for the notice expires.”
Failure to comply could become a criminal offence, meaning the council could then prosecute or clear the site itself and recover the costs.
The council added: “We understand and share residents’ frustrations about the fly-tipping.
“This is why we served an enforcement notice to start the legal process for clearing the site and restoring the land to its previous state.”
