Bins overflowing with everything from fridges to pig skins in Kauarapaoa Valley are an "absolutely disgusting" eyesore, one resident says.
And it may not be better in the city with Koha Shed manager Sherron Sunnex suggesting an inorganic collection once a year might curtail some of the illegal dumping happening in Whanganui.
Volunteers recently spent two days clearing rubbish that had been dumped after hours at the Duncan St premises and the Koha Shed is not the only place copping it.
"A kind person who wants to remain anonymous donated money to help with dumping costs," said Ms Sunnex.
"We have put a lot of the clothing in donation bins because they are still suitable for rags.
"Another kind person has said we can use a space on their farm to burn some of the wooden rubbish."
Ms Sunnex said the Koha Shed has now placed a ban on after-hours deliveries because so much rubbish is being dumped.
A post on Facebook page Buy, Sell, Swap Wanganui shows overflowing Waste Management bins in Kauarapaoa Valley, west of the Whanganui River.
"It's absolutely disgusting and a eyesore, not to mention the poor blokes who have to get rid of it all," wrote poster Channelle Rogan.
"These skip bins are for OUR community not for people who live in town ... as soon as these bins are emptied they are full within a day.
"The rubbish ranges from all sorts from rubbish bags to fridges, washing machines, old mattresses, to dirty, smelly pig skins," she said.
One responder said it was doubtful city folk would drive that far and they are more likely to dump their rubbish at South Beach.
Another said the Waste Management bins at Mangamahu are overflowing in a similar fashion.
Ms Sunnex said dump fees may be unaffordable for some people or they are simply unwilling to pay them.
"An annual inorganic collection might just encourage more people to dispose of more of their junk that way rather than dump it illegally."
Ms Sunnex said the Whanganui District Council has to bear the cost of illegal dumping and an organised collection may be more cost-effective in the long run.
