Open bags of rubbish have been left next to overflowing bins at a popular beach front car park where travellers have been staying for the last week.
Up to 12 caravans and 15 other vehicles pitched up at the Blackpill car park in Derwen Fawr Road, Swansea, last week. It is the second time the site has been used by travellers this year.
The families have now moved on but a large amount of rubbish has been left behind, although this is in line with what the travellers had been asked to do, according to Swansea Council.
Bags of cans and bottles have been left next to bins that were full and cardboard boxes were left in the corner of the car park.
Swansea Council said it was aware of the waste and confirmed that council officers met with the families to ask them to bag their refuse before moving on.
A spokesman for the council said they were "satisfied that they have done this prior to them leaving."
Arrangements are now being made to have the waste removed as some of the rubbish appears to be falling out of the bags and blowing across the car park.
Swansea has two long-standing sites for travellers; an official site in Pant y Blawd in Llansamlet, and a 'tolerated' site in Swansea Vale.
Travellers have in recent years also arrived and set-up camp on St Helen's recreation ground next to Mumbles Road and a mansion overlooking Swansea Bay.
What are the rights of travellers?
A spokesman for Swansea Council said: "Our officers previously talked to the families about their presence on site and they committed to bagging their household waste so we could collect when they departed.
"We are satisfied that the [sic] have done this prior to them leaving and we can now arrange to collect the bagged waste and carry out additional cleansing.
"Whenever Traveller families move onto a site illegally, the Council is required to manage it appropriately in line with specific Welsh Government guidance."
