The project would facilitate a new housing development in the area.
However the Ballymore Eustace Trout and Salmon Anglers Association appealed that decision to the planning board, but the appeal was rejected last week.
The Treatment Plant was identified by Irish Water in its Investment Plan in 2017 as a site that requires an upgrade to meet potential development pressures in the locality.
Last September the County Council granted permission for the project, however the Ballymore Eustace Trout and Salmon Anglers Association appealed that decision to the planning board, but the appeal was rejected earlier this year.
Local Councillor Gerry O’ Neill says there is still some confusion surrounding the project as some of the houses would be situated across the border in County Kildare so they may not be added to Wicklow's housing stock.
