Two million leaflets are to be sent to households next week informing people about the installation of water meters.
The installation of the meters will begin this summer and the introduction of water charges is due from next year.
Officials from the Department of Environment and members of the opposition both discussed the issue with the Troika this week.
By the end of this year, 160,000 meters will be in place and 486,000 will be installed by the end of 2014.
Irish Water Programme Director and acting chief executive of Bord Gáis John Barry said they would be liaising extensively with local communities to allay fears about the installation of more than 1m meters over the next three years.
Mr Barry said that while it is a concern that there could be trouble during the installation period, he hoped this would not be the case.
He added that many of the 2,000 jobs created by Irish Water would be made up of local people who will install them.
Mr Barry also said the leaflet cost on average 6 cent each.
Minister of State Fergus O'Dowd said those who will not have a meter installed before water charges are introduced would be assessed on "usage, occupancy and best practice in other countries".
People Before Profit Alliance TD Richard Boyd Barrett said he told the Troika during talks earlier today that water charges were not sustainable.
