Greater Dublin Drainage Project


Client: Irish Water

Greater Dublin Drainage is a major infrastructural project led by Irish Water. The project, which is being undertaken to provide a much-needed wastewater treatment capacity for the Dublin region, comprises an underground orbital sewer and two pumping stations; a wastewater treatment plant (WwTP) on a 23-hectare site at Clonshaugh; and an outfall pipe from the wastewater treatment plant discharging 1km north-east of Ireland’s Eye.


Irish Water is currently progressing the studies required to prepare the planning application for the GDD project. FAC forms part of the specialist team brought together to carry out the Environmental Impact Assessment (EIA) of the proposed treatment plan and pipeline route. FAC’s role is to prepare the socioeconomic chapter which explores the impacts of the proposed development on human beings. The assessment considers the attributes and characteristics associated with the following aspects, and proposes mitigation measures to address any impacts that may arise:

  • Demographics
  • Community and Residential settlement
  • Economic activities and employment
  • Public Amenity and Community Infrastructure
  • Tourism
  • Access and connectivity

The planning application and accompanying EIS is expected to be lodged to the relevant authority, An Bord Pleanála, in late 2016.
