Plans to pipe water from the River Shannon to a reservoir in Dublin have gone out for public consultation.
Uisce Éireann says it's a "once in a generation" project, which would connect the Parteen Basin with a treatment plant in Birdhill in Tipperary and Peamount in Dublin.
It's due to become a "spine" to serve communities along the route, with the potential for more infrastructure to connect it further out.
This project will provide Dublin, Meath, Kildare and Wicklow with a resilient, safe, secure water supply.
In addition, it will enable supplies currently serving Dublin to be redirected back to Louth, Meath, Kildare, Carlow and Wicklow, providing security of supply to homes and businesses, which will support growth and regional development.
The Consultation will run until 4 March 2025.
