  • Annsbrook, Approx 10km north of Dublin airport and approximately 2.7km west of Lusk with a marine outfall in the Northern Outfall Study Area, in the vicinity of Loughshinny
  • Newtowncorduff, Approx 10km north of Dublin airport and approximately 1.0km west of Lusk, with a marine outfall in the Northern Outfall Study Area, in the vicinity of Loughshinny
  • Clonshagh/ Clonshaugh, Approx 2.2km east of Dublin Airport, with a marine outfall in the Southern Outfall Area, to the north east of Ireland’s Eye.

are the three emerging preferred site options for the proposed regional wastewater treatment plant in north Co Dublin, part of the Greater Dublin Drainage project. Each of the three preferred site options includes a site of approximately 20ha in area, associated orbital pipeline routes from the load centres to the wastewater treatment plant, pipeline routes from the wastewater treatment plant to the coast, marine pipeline routes and a marine outfall location.  All three project options will now be considered further in detail before one emerging preferred project option is decided on and a planning application is made to An Bord Pleanála.

Fingal Co Council has published The Alternative Sites Assessment and Route Selection Report (Phase 2): Emerging Preferred Sites and Routes and maps. The Report and maps can be downloaded free of charge from  Digital copies of the Report can be obtained at a cost of €5.  Printed copies will be available to view at Fingal Co Council headquarters and at local libraries.  Printed copies will cost €150 to buy.

Starting today Fingal County Council will hold their third round of non-statutory public consultation for eight weeks, until 6th July, to give stakeholders and the general public another opportunity to meet with the Project Team and give their views and concerns on the project.  The public consultation opportunities include four Open Days, to be held in Fingal County Council headquarters in Swords on

  • Wednesday, 30th May from 2pm – 8pm
  • Saturday, 2nd June from 11am – 4pm
  • Thursday 14th June from 2pm – 8pm
  • Saturday, 16th June from 11am – 4pm

The Project Team will be available at the Open Days to discuss the Report, answer questions and listen to views. People can also email

According to Peter O’Reilly, Project Engineer, Fingal County Council, the preferred site on which planning permission will be sought, “needs to be a combination of the best location for the wastewater treatment plant, the new sewer and the marine outfall.

“We’re looking for the option that is best for the project, the one that will have the least impact on people and the environment.  These three preferred sites all have merits. Therefore, in order to decide on the site that is most suitable for all three elements of the project, a lot more detailed technical studies will have to be carried out.”

“Since last December, after the eight weeks of the last non-statutory public consultation on the nine large land parcels identified by the Project Team, our technical experts have been engaged in a step-by-step qualitative process to identify the three emerging preferred site options”, Peter O’Reilly continued. “Using technical and environmental criteria, detailed surveys, consultations and workshops, they believe they have now identified the three sites on which the project will have the least impact and we will now consult with everybody on these sites. The feedback we get will be reviewed and considered by the Technical Team as they move towards selecting a preferred site, orbital pipeline route and marine outfall location”.

The Report published today sets out the process used to identify and appraise the site options relating to the three elements of the Greater Dublin Drainage project; the site for the regional wastewater treatment plant, the pipeline routes for the new orbital sewer and outfall locations to the Irish Sea.

“We want to hear what people think should be considered as part of the selection for the final preferred site route and marine outfall”, Peter O’Reilly concluded, “and to hear any information relevant to the development of this much needed project. The Technical Team has been working closely with a team of 13 environment protection specialists and the three emerging preferred sites balance all their views.  Now we want to hear the views of the public again, before we go any further.”

This is the third in a series of non-statutory consultations held by Fingal County Council.  An Bord Pleanála, the independent planning board will carry out its own statutory public consultation when a planning application is made for the wastewater treatment works, the orbital sewer and the marine outfall.  All stakeholders will have another opportunity to give their views to An Bord Pleanála, at that stage.

The new regional wastewater treatment plant is needed in addition to the Ringsend plant, which is currently planned to be extended to its full capacity at which it will be able to treat wastewater from the equivalent of 2.1 million people.  The regional plant in north Dublin will initially be approximately one sixth the size of the Ringsend plant.  It will treat 350,000 population equivalent in 2020 when the plant opens and will be capable of treating up to 700,000 population equivalent, when it is at full capacity by 2040.  (Population equivalent includes wastewater from industries, hospitals, schools, offices, businesses, etc as well as homes.)
