Residents in Splott are concerned about fly tipping on their streets.
They say the area is seeing a rise in the illegal dumping of waste.
Large items, such as sofas and fridges, are being left on land which does not have a license to take them.
Keep Splott Tidy is a community group which has partnered up with Cardiff Council to tackle the issue.
Peter Durrant is the Treasurer of Keep Splott Tidy. He says the amount of dumped waste is harming the local community.
“Normally the people who do it come from outside the community, and this is what’s really annoying to most residents.”
“It’s just a blight on the community and once one person dumps and its not picked up fast enough, then other people think it’s quite okay to put household rubbish there as well.”
“Before you know it, it becomes a huge mess.”
Mr Durrant is calling for harsher fines and the confiscation of vehicles.
The current penalties for fly-tipping carry a potential fine of £50,000 or up to a six month prison sentence.
Cardiff Council are advising people to take down car details and report any incidents.
A spokesman for the Council said “Fly-tipping is completely unnecessary – it damages the environment and costs the tax payer a significant amount of money each year.”
“We frequently carry out patrols with partner organisations and stop and request documentation from people carrying waste in their vehicle and this will continue.”
Two of the Council’s partner organisations, Keep Splott Tidy and Keep Roath Tidy, have recently been nominated for the ‘Cleaner Communities Award’ for helping keep Cardiff’s streets clean.
