Uisce Éireann welcomes settlement in Judicial Review Proceedings on the Greater Dublin Drainage Project

Uisce Éireann has reached an agreement to settle judicial review proceedings initiated in the High Court concerning aspects of the Greater Dublin Drainage Project. The settlement was achieved following constructive engagement between all parties and avoids the need for a full court hearing. As part of the agreement Uisce Éireann committed to some additional measures, to further enhance public confidence in the environmental benefits of the project.

Uisce Éireann acknowledges and appreciates the decision of the courts to expedite the judicial review proceedings for the Greater Dublin Drainage Project and remains committed to working collaboratively and transparently with all stakeholders to deliver sustainable solutions that protect our environment and support future growth.

This resolution reflects Uisce Éireann’s commitment to delivering critical infrastructure in compliance with planning and environmental regulations, while maintaining open dialogue with communities and stakeholders. The Greater Dublin Drainage Project remains vital to ensuring sustainable wastewater treatment capacity for the region. 

Uisce Éireann’s  Infrastructure Delivery Director Maria O’Dwyer said, “Uisce Éireann is delighted to secure an agreement and move forward with this critical project. The delivery of the Greater Dublin Drainage project is an essential part of Uisce Éireann's investment in new wastewater infrastructure in Greater Dublin and will facilitate housing and growth while protecting public health and safeguarding our environment. While there are several remaining statutory processes to be completed, construction contractor procurement will commence in February 2026. When the contractor procurement process is complete, construction work on the GDD Project is expected to be completed over a four year period".
