A €1.3 billion drainage project for the Greater Dublin Area has been approved.
Uisce Éireann confirmed An Coimisiún Pleanála has given the go-ahead for the Greater Dublin Drainage Project.
It will serve parts of Kildare, Meath and north Dublin, providing wastewater treatment for up to 500,000 people.
The Ringsend plant, currently at full capacity, cannot meet growing demand, according to Uisce Eireann.
The new treatment facility will be built on a 30-acre site at Clonshaugh.
It will be linked to Blanchardstown by an underground sewer and connected to the sea at Baldoyle via a 6km outfall pipe.
The project was first submitted in 2018.
Although approved, objectors have eight weeks to seek a judicial review.
The scheme is due to be operational by 2032.
