Greater Dublin Drainage
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.
GDD represents the next major step in the development of our wastewater infrastructure for Dublin and the surrounding counties. Once operational, the GDD project will have the capacity to provide wastewater treatment for the equivalent of half a million people living and working in this area.
GDD is a key part of Uisce Éireann’s investment in new wastewater infrastructure in greater Dublin and will protect public health, safeguard our environment and facilitate growth to 2050.
