Supermarket bosses in Lynn have been warned they could be fined unless they act to stop their trolleys being dumped around the town.
The threat was delivered as council bosses were urged to do more to ensure trolleys are returned to the businesses they came from, rather than seeing them tipped into town waterways.
Gary McGuinness, who represents the South and West Lynn ward, told Thursday’s full council meeting that he had been contacted by several residents in his area about dumped trolleys.
He said, in that case, they came from the Morrisons store, which were not collected for several days.
He told the meeting he was concerned about the impact on perceptions of the town, particularly among visitors attending Sunday’s Grand East Anglia Run (GEAR) event.
He added: “We’re going to have people coming from all over the country running down a stretch of river strewen with trolleys and we need to do better as a borough.
“I think it’s time to bring back the trolley man. It doesn’t seem to me they’re taking their responsibilities seriously.”
Environment portfolio holder Brian Long said store bosses had pledged to introduce their own system in order to end the previous use of an outside contractor to enforce the rules.
But he added: “It’s proving far from robust and we should consider our options on taking legal recourse.
“We might start fining them again so they concentrate their efforts on looking after their equipment, which they allow to leave the premises and end up in all sorts of places.
“I dont think the supermarkets are doing it under their current scheme.”
Flytipping into waterways has been an ongoing concern for council officers and staff from the area’s internal drainage board.
Board officials have previously reported spending as much as £30,000 to clear rubbish from the town’s rivers and drains.
