A site near Dublin Airport has been chosen for a new 'super' sewage treatment plant, it was announced.
Planning permission for the wastewater treatment plant at Clonshaugh, north Dublin, and an outfall pipe 6km out to sea from Baldoyle will go to An Bord Pleanala next year.
Project managers with Dublin Greater Drainage said the site, which is 2.2km east of Dublin Airport and between the Malahide Road and the M1, is ecologically and environmentally better. Two other locations near Lusk in north Co Dublin had also been shortlisted by for the facility.
Plans also include a 26km orbital sewer to pump sewage from across Dublin and parts of Kildare and Meath.
More than 10,000 residents lodged objections against the facility, fearing it will have a detrimental effect on farming and horticulture and destroy the local fishing industry and coastline.
A statement released on the Greater Dublin Drainage website said the preferred site was the best solution for the future development of waste water treatment capacity in the wider Dublin region. It said tunnelling of the preferred outfall is technically easier and the outfall location has a greater depth of water for treated water discharged into the sea.
It would also have the shortest pipeline and therefore a shorter construction time and it is closest to the existing areas where waste water is drawn from and so will be more flexible in serving schools, hospitals, houses and industry immediately as well as enabling additional capacity.
It said the estimated overall cost of half a billion euro would be more than 80 million euro less than other options studied.
Senator Darragh O'Brien said he was gravely disappointed that the Department of the Environment and Fingal County Council had decided to proceed with what he described as a "monster" sewerage plant.
"I am opposed to this plant being located anywhere in Fingal. I would not wish this plant on any community," he said.
