Irish Water has said that it is planning to cut 1,200 people from its workforce over the next six years.
The company expects that a voluntary redundancy scheme will be required at some point to achieve its target.
The amalgamation of the water services functions and employees of 34 local authorities left Irish Water substantially over-staffed.
It is under constant pressure to reduce costs.
It has a target of €1.1bn of savings by 2021.
This morning in a presentation to stakeholders Irish Water says that one third of those savings will come from reducing staff numbers.
The company says the 1,200 jobs to go by 2021 will be in addition to the 300 jobs that have been cut since last year.
Up to this point, the reductions have been achieved without redundancies - through natural attrition and not filling roles that have become vacant.
Irish Water says it will continue this approach but that a voluntary redundancy scheme will also be needed to reduce the numbers.
Meanwhile, the CEO of Ervia, Irish Water’s parent company, has said Irish Water will improve water supplies.
Speaking on RTÉ’s Morning Ireland, Michael McNicholas said that Irish Water will be investing €5.5bn in order to improve wastewater infrastructure, eliminate all boil water notices, eliminate discharge of raw sewage into bathing water, reduce the level of leakage by 10% and significantly improve the drinking and waste water capacity across the country.
He added that it will also restructure its service delivery model and reduce staff levels.
"We're going to do that, first of all by moving from 31 local authorities down to a single national utility which creates economies of scale.
"That allows centralised functions, it allows us to regionalise things and that allows us to take some of those jobs out. We're also going to invest in technology that allows us to run our treatment plants differently.
"It allows us to retrain and re-skill people and it allows us to move to the kind of level that a modern utility will have in terms of staffing."
Mr McNicholas also said that nearly 54% of people are projected to pay the second Irish Water bill - an increase of 10% on the first billing cycle.
Sinn Féin's finance spokesperson has said it would be better if Irish Water concentrated on fixing leaks rather than cutting staffing levels.
Speaking on the same programme, Pearse Doherty said that Irish Water's priorities were wrong.
He said: "The best way to drive efficiencies is to deal with the treated water that is being lost through the system day in, day out.
"We know the type of money that is being spent by Irish Water putting pipes into the ground which is minimal compared to the costs of putting water meters outside people's homes or indeed in consultancies or other costs associated with Irish Water.
"The priorities of Irish Water are all wrong."
He added that the plan outlined by Irish Water today is not permissible under law at this time.

This is a kick in the teeth to SIPTU who represent local county council water workers. Wonder what Jack O'Conner and the SIPTU Cork conference thinks about that? The SIPTU conference is taking place at the moment in Cork City.
2021 is about the time the Service Level Agreement between County Councils and Irish Water runs out and all local water workers' jobs will be at risk.
