Kathryn Dedini grew up in Ashmont and said it was painful to see the McNickle Street reserve next to the Murrumbidgee neglected and covered in garbage.

"You see places like that and you know how beautiful they are and how great it can be ... and then you go down there and you see it's basically treated with a high level of disregard," she said.

"I just couldn't leave it like that ... I want my kids to be able to go down there and enjoy the space and feel what I felt going there as a kid."

Ms Dedini cleared the reserve in a mammoth three day task which included wearing personal protective equipment to move broken car windows, building waste and dirty syringes.

Ms Dedini's efforts were shared on social media by a friend and she was offered a skip by Wagga's Cleanaway garbage collection service.

Cleanaway Riverina territory manager Andrew Dickins said "as a local" he wanted to help out.

"When it comes to waste ... we're trying to make as sustainable a future as possible. It's something I'm really passionate about," Mr Dickins said.

"It's paramount we need to be looking after our environment as much as possible ... we're living in a world with finite resources."

Mr Dickins urged the community to "do the right thing" and encouraged people to come to them with any questions about where to dispose of their waste.

Ms Dedini said she always carries plastic bags in the car and will pick up rubbish in other parts of Wagga when out with her four children, who will help if it is safe to do so.

"Usually they discuss with me things about how it impacts the animals and the different environmental aspects about dumping," she said.

She said there was no reason why other people in Wagga couldn't do the same.

"If you're walking your dog and you bring a doggy bag, just picking up rubbish as you go and chucking it in the bin is not overly difficult," she said.
