A promotional video is available to view online, explaining how residents can get involved in this important event, to help keep their local areas clean and tidy.
The event is organised in partnership with Cheshire West and Chester Council, Flintshire County Council and Natural Resources Wales.
Last year 256 volunteers from across all areas joined 48 partners and sponsors who collected 416 bags of litter, 25 shopping trolleys and large amounts of debris and wood. 700 trees were planted as well as 40,000 bulbs.
Cheshire West and Chester Councillor Lynn Riley, Executive member for Localities said: "Please sign up because you can make a big difference to the River Dee, its surrounding areas or local waterways and canals joining the Dee."
"This is an event in which we can take a great deal of pride as well as improve the local environment. We want to do better than last year which was very successful. So please come forward and join in this important event."
