The Chairman of the Future Funding of Domestic Water Services has said significant progress has been achieved with the committee’s final report.
Speaking on RTÉ’s Drivetime, Independent Senator Pádraig Ó Céidigh said the committee has produced the best possible result.
Mr Ó Ceidigh said he is proud of the process; the engagement and the democracy of the rigorous debating.
He added there is now a way forward for Government on the topic of water.
Earlier the Dáil debated a motion on the final report, which was agreed last night, while TDs will vote on the motion tomorrow.
After an acrimonious week, Fine Gael and Fianna Fáil yesterday reached agreement on water, an issue that has dominated the political agenda for the past three years.
The two parties supported the final report, while the other members of the committee voted against it.
The deal came after legal advice supported Fine Gael calls for the inclusion of the term "excessive usage of water" and the imposition of levies for those who use excessive amounts.
There was a compromise on the definition of excessive usage which was set as 1.7 times average household usage.
However, consideration is also being given to average individual usage of 133 litres per person per day.
The issue will ultimately be decided by the regulator.
Both parties say around 8% of households could be affected.
The final report also states that meters should be installed in all new builds.
During the debate, Sinn Féin's Mary Lou McDonald accused the Taoisaech of cobbling together a deal on water with Fianna Fáil that sought to "subvert the will of the people" on water.
Politically, Fine Gael has described the report as a vindication of its position.
Fine Gael TD Colm Brophy, a member of the water committee, has said a process will be worked out through legislation on how to deal with those who do not pay the excessive water charge.
Speaking on RTÉ's Morning Ireland, he said his own personal view is that it could be taken from a person's wages because he said he does not think people have the right to ask others in society to pay for them to waste water.
He described the final report on water charges as positive and what he said was "the middle ground in Irish politics came together" and found a consensus to work together to find a working solution.
Sinn Féin, Solidarity-People Before Profit and the Independent committee members have accused Fianna Fáil of a U-turn and say water charges could now be brought in through the back door.
Fianna Fáil's Barry Cowen said he did not care how the deal was spun by others - water charges, he said, were gone. But many in his own party are very unhappy about how he has handled the issue and want to avoid any recurrence.
Speaking on RTÉ's Morning Ireland, water committee member Mr Cowen said charges have now "been done away with" and the Dáil can move on to deal with more pressing matters such as housing and Brexit.
Solidarity-PBP TD Paul Murphy, who is also a member of the committee, said it was "outrageous" that Fianna Fáil could say it opposed water charges, but then agree to measures.
Speaking on the same programme, he said that if efforts to impose charges were brought in, then mass protest and mass organisation of non-payment would resume.
"We have beaten them before and we can beat them again," said Mr Murphy.
Last night, Minister for Housing, Planning and Local Government Simon Coveney said he was confident he could bring forward legislation based on the report before the Dáil breaks for the summer.
