Greater Dublin Drainage Project
A new regional wastewater treatment facility and associated infrastructure to serve Dublin and parts of Kildare and Meath.
Greater Dublin Drainage
As our population and economy grow, so too does the volume of wastewater. The amount of wastewater generated in greater Dublin is projected to increase by over 50% in the period to 2050.
Greater Dublin Drainage (GDD) is a project to develop a new regional wastewater treatment facility and associated infrastructure to serve Dublin and parts of the surrounding counties of Kildare and Meath.
GDD represents the next major step in the development of wastewater infrastructure for Dublin and the surrounding counties. Once operational from 2026, the GDD project will have the capacity to provide wastewater treatment for the equivalent of half a million people to support the needs of our growing population and economy.
The GDD project proposes a new regional wastewater treatment facility to be located in the townland of Clonshaugh in north county Dublin, an underground orbital sewer from Blanchardstown to Clonshaugh, a new pumping station at Abbotsown, a partial diversion of the north fringe sewer, and an outfall pipeline to return the treated water to the Irish Sea. The project also includes a regional sludge treatment centre at the new GDD facility and an associated biosolids storage facility at Newtown near Kilshane Cross.

GDD planning application and statutory consultation
On 20 June 2018, Irish Water made a planning application for strategic infrastructure development to An Bord Pleanála for the Greater Dublin Drainage Project. The planning documentation can be viewed on the GDD Application Website.
The planning application includes an Environmental Impact Assessment Report (EIAR) and Natura Impact Statement (NIS). For a guide to the GDD Planning Application please see the latest GDD Project Update.
The application also includes a Public and Stakeholder Participation Report which documents how consultation feedback has informed the development of the GDD project. A community benefits scheme is also proposed as part of this project. Irish Water wishes to thank all of the individuals and organisations who have participated in the consultations on this project to date.
