The Cabinet is meeting this morning to sign off on the revised lower water charges before they are outlined in the Dáil this afternoon.
Ministers are expected to include a series of compliance measures to tackle those who won't pay, which could see penalties added and them taken to court.
It is expected that as part of the Coalition's plans to make the charges affordable, legislation will be introduced around the capping of the charges.
We will find out later that the charge will range from €60 for a single adult household to €160 for families, and will be guaranteed not to increase for at least four years.
Charging won't commence until January and the first bill won't arrive until April.
Compliance measures or penalties will also be announced - those who don't pay could face increasing charges and be taken to court and the bill attached to the home people try to sell.
The Government will also introduce legislation to ensure Irish Water will never be privatised.
