Welcome to Greater Dublin Drainage
On Wednesday 20 June 2018, Irish Water made a planning application for strategic infrastructure development to An Bord Pleanála for the Greater Dublin Drainage Project.
Greater Dublin Drainage (GDD) is a project to develop a new regional wastewater treatment facility and associated infrastructure to serve north Dublin and parts of the surrounding counties of Kildare and Meath.
As our population and economy grows, 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. We must collect and treat this wastewater so that the treated water can be safely returned to the environment.
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 represents the next major step in the development of our 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.
GDD is a key part of Irish Water’s investment in new wastewater infrastructure in greater Dublin and will protect public health, safeguard our environment and facilitate growth to 2050.
