Plans for a new €12 million white-water rafting circuit and polo pool at George's Dock are being considered by Dublin City Council.
The proposals had been dismissed by the previous administration, with former lord mayor Nail Ring claiming "it could be a white elephant".
However, since new councillors were elected last May, the council is giving the plans a second look.
The proposal are for a mechanically-propelled rafting facility with a water polo pitch and an emergency service training centre.
According to the development plans, the facility would utilise the existing George's Dock basin - which is a protected structure.
It would include other features such as a slalom course and kayak / raft conveyor.
Derek Kelly, the administrative officer at Dublin Docklands, said the council thinks the plans could regenerate the area.
He explained: "They see the value of this project.
"At the moment, anybody who knows George's Dock, is sitting idle... it's derelict. This is what the city council sees as a good activation of the area."
Submissions can be made to the council about the plans until October 3rd.
