The demonstration will take place at 5pm outside the Dáil and coincides with Sinn Féin's Private Members time on Tuesday and Wednesday to table a motion to abolish the charges.
The motion has been signed by 39 anti-water charges TDs.
In addition, the motion calls for the government to set a date for a referendum to enshrine the public ownership of water services in the Constitution of Ireland.

Sinn Féin TD Eoin Ó Broin said: "The overwhelming majority of people voted to scrap water charges and abolish Irish Water.
"The latest figures from Irish Water clearly demonstrate that people are opposed to paying this unfair tax.
"We expect all the TDs elected on the anti-water charges platform to vote in favour of this motion.
"We also expect the Government to respect the democratic will of the people and to scrap this charge."
Deputy Richard Boyd-Barrett of People before Profit said: "It is absolutely vital that we mobilise the biggest number of people this Wednesday at the Dáil to demand that those TDs who promised to abolish water charges and Irish water to keep their promise. Democracy demands it."
