New regional wastewater treatment facility is being proposed

Greater Dublin Drainage (GDD) is the development of a new regional wastewater treatment facility and associated infrastructure to serve the growing population of north Dublin and parts of the surrounding counties of Kildare and Meath.

The new regional wastewater treatment facility is being proposed in order to protect public health, safeguard the environment and facilitate the social and economic growth of the Greater Dublin Area.

Greater Dublin Drainage Project

On 20 June, Irish Water made a strategic infrastructure planning application for the Greater Dublin Drainage project to An Bord Pleanála. On 25 July, Irish Water notified An Bord Pleanála that it had discovered that a small number of the supporting appendices to the Environmental Impact Assessment Report (EIAR) were inadvertently omitted from the submitted documentation.

The omitted information comprised a number of supporting appendices on the terrestrial and marine ground investigations and previously published project reports for the site investigation stage of the Regional Biosolids Storage Facility project. A number of drawings relating to landfill/quarry locations and road/rail/utilities crossings were also omitted.

Additional Statutory Consultation for GDP

The omission of the supporting documentation does not impact the findings and conclusions of the Environmental Impact Assessment Report. The data from these reports had already been incorporated in the main Environmental Impact Assessment Report.

An Bord Pleanála has notified Irish Water that it intends to hold an additional period of statutory consultation for the Greater Dublin Drainage Project from Thursday 13th September until Thursday 18th October 2018 inclusive. 

Planning Application and EIAR public consultation

Irish Water welcomes this direction from An Bord Pleanála and will place the GDD planning application and EIAR (including the previously omitted appendices) on public display from Thursday, 13 September 2018 at the following locations:

  • The Offices of An Bord Pleanála, 64 Marlborough Street, Dublin 1
  • The Offices of Fingal County Council, County Offices, Grove Road, Blanchardstown, Dublin 15
  • The Offices of Fingal County Council, Fingal County Hall, Main Street, Swords, Fingal, Co. Dublin
  • The Offices of Dublin City Council, Civic Offices, Wood Quay, Dublin 8

Anyone who has made an observation/submission to An Bord Pleanála as part of the recent statutory consultation does not need to resubmit their observation/submission. All previous consultation submissions remain valid and will be considered by An Bord Pleanála. Anyone who has previously submitted an observation/submission and would like to make an additional observation/submission may do so directly to An Bord Pleanála at no additional cost.

Compulsory Purchase Order

A further five week period for any objections to the compulsory purchase of lands and rights over land in connection with the Irish Water Compulsory Purchase (Greater Dublin Drainage Project) Order, 2018 will also be held. Any submissions or observations may be made in writing to An Bord Pleanála, 64 Marlborough Street, Dublin 1, before 5.30pm on Thursday 18 October, 2018.

The Greater Dublin Drainage project will help to ensure that the wastewater generated every day in our homes, schools and workplaces will continue to be treated safely in compliance with the EU and national wastewater treatment regulations.
