Environmental Impact Assessment

An Environmental Impact Assessment Report (EIAR) was prepared by Uisce Éireann to inform the Environmental Impact Assessment (EIA) process and was submitted to the planning authority for evaluation along with the planning application documents.

The EIAR submitted as part of the planning application is available here.


On 20 June 2018, Uisce Éireann submitted a planning application to An Bord Pleanála for the Greater Dublin Drainage project (the GDD Project), complete with an Environmental Impact Assessment Report (EIAR) and Natura Impact Statement (NIS). The application was made under planning legislation that relates to Strategic Infrastructure Development. A Compulsory Purchase Order (CPO) was also submitted for confirmation to An Bord Pleanála. 

The GDD planning application is available here. An Bord Pleanála then held statutory public consultation including an oral hearing.

In November 2019, An Bord Pleanála granted planning permission and confirmed the CPO for the GDD Project. This planning permission was quashed following the issue of legal proceedings and a Court hearing. The planning application was subsequently remitted back to An Bord Pleanála by Order of the High Court on 16 July 2021 for a fresh decision (the Remittal Application). The Board subsequently wrote to Uisce Éireann in August 2022 providing Uisce Éireann the opportunity to update, where appropriate, the Environmental Impact Assessment Report and Natura Impact Statement and any other information submitted.

Uisce Éireann submitted further information to the Board in October 2023 in response to this direction (the Further Information). The Further Information addresses changes that have occurred in the Environmental, Policy and Legislative context since the original application was made in 2018.

The planning application and Further Information, along with other material on the GDD Project, can be viewed and downloaded on the project website:

The Board is now inviting submissions or observations on the Further Information.
