Residents and local businesses on Althorpe Street have been concerned about the growing pile of unsorted rubbish in the car park at The Union, a 187-bed student accommodation block by the canal.
It has recently grown into a mountain and local residents fear the presence of vermin.
On resident said: "Students are now having to look out onto this sight, whilst paying upwards of £171 per week.
"Much of this material could easily have been dropped off to Action21’s reuse centre which is just around the corner in Court Street."
A spokesperson for The Union said: “We absolutely recognise the frustration of local residents. Unfortunately, the property has been missed by our council bin collections, leaving us without a collection for over a month in what is our busiest time. Our team has worked tirelessly to manage the situation at our own expense.
“We understand that this issue is also being faced by local residents. We are in conversation with the council to get the items removed from site as quickly as possible.”
A spokesperson for Warwick District Council said they are aware of the problem, adding: “The Union student accommodation at Althorpe Street is scheduled for weekly refuse collections as well as fortnightly recycling. We will investigate why the collections may have been missed.”
