The Right2Water campaign will outline its plan for tomorrow's national assembly later.
The protest against water charges is beginning outside the Dail at 1pm tomorrow.
Groups from around the country are expected to attend the demonstration, as well as activists from abroad, including the Detroit Water Brigade.
Meanwhile, the We Won't Pay group - including deputies Paul Murphy, Joe Higgins and Ruth Coppinger - is calling for people to remain on into the evening, to maintain a presence outside the Dáil.
