Welcome to Greater Dublin Drainage

Greater Dublin Drainage is needed to provide wastewater treatment capacity for the Dublin region.

The Greater Dublin Drainage team completed a site selection process in 2013 and identified the preferred option as being:

an underground orbital sewer and two pumping stations;
a wastewater treatment plant (WwTP) on a 23-hectare site at Clonshagh (Clonshaugh);
an outfall pipe from the wastewater treatment plant discharging 1km north-east of Ireland’s Eye.

This offers the best solution for the future development of wastewater treatment capacity in the Greater Dublin Area

Following completion of the site selection process and extensive input from public consultation in 2013, Irish Water is progressing the studies required to prepare the planning application for the GDD project. A number of additional studies are now underway or planned to inform the Environmental Impact Statement (EIS). These include Marine Ground Investigations in Baldoyle Bay.

Irish Water is managing the planning stages of the GDD project which involves the preparation of a planning application to be submitted in the first half of 2017 to the independent planning authority, An Bord Pleanála, for its adjudication.
