The Dáil has passed a motion that will extend current and future Freedom of Information legislation to cover Irish Water.
It will be applied retrospectively to the company's set up date July 17, 2013.
It is now up to Public Expenditure Minister Brendan Howlin to decide exactly when Irish Water will start taking FOI requests, but it won't be the usual six months:
"It is reasonable that Irish Water be allowed some time to make such administrative arrangements," Minister Howlin said in the Dáil.
"But in the circumstances I believe that a period of six months is too long.
"I believe that 30 working days would be the appropriate timeframe to enable Irish water make these necesssary preparations."
