What’s Happening Now?

Until end-2017

Irish Water is continuing to progress the environmental studies required to prepare a planning application for the GDD project. A range of environmental studies and assessments have been conducted including both land-based and marine-based surveys. The Environmental Impact Assessment Report (EIAR), which includes the findings of these environmental studies and assessments, will be submitted to An Bord Pleanála as part of the planning application in 2018.

Prior to submitting a planning application for GDD in 2018, we are undertaking a public information campaign for the Greater Dublin Drainage project in November 2017. We are providing information and holding public information events on the development of this vital piece of regional wastewater infrastructure, which will serve the equivalent of half a million people into the future.

The public information events will take place on:

  • Tuesday, 21st November 2017 at Portmarnock Hotel and Golf Links from 2-8pm
  • Monday, 27th November 2017 at National Sports Campus Conference Centre in Abbotstown from 2-8pm
  • Wednesday, 29th November 2017 at Hilton Hotel, Northern Cross in Clonshagh (Clonshaugh) from 2-8pm

You are welcome to come along and meet the team to find out more about the Greater Dublin Drainage Project.


What happens next?

Planning Stage: 2018

The planning application, including an Environmental Impact Assessment Report (EIAR) and Natura Impact Statement (NIS), will be submitted to An Bord Pleanála in 2018.

Following the submission, there will be a period of statutory public consultation carried out by An Bord Pleanála.

Design & Procurement: 2019 – 2021 approximately

Irish Water will hold a public procurement process to appoint contractor(s) to design, build and operate the GDD project.

Subject to the planning permission being granted and once contractor(s) have been selected, the construction process will begin with the Regional Biosolids Storage facility. This is envisaged to take approximately 18-24 months and will be completed by 2021.

Construction: 2021 – 2025

Construction of the GDD wastewater treatment plant and the associated orbital sewer, pumping station and marine outfall is estimated to take three years and will begin, subject to planning permission, in 2021.

Irish Water will liaise closely with local communities throughout construction and is committed to ensuring that all works will be undertaken in a safe and environmentally responsible manner.

It is intended that the new regional wastewater treatment facility and associated infrastructure serving greater Dublin will become operational from 2025 and will protect public health, safeguard the environment and facilitate the development of our communities and business to 2050 and beyond.

The GDD project, when combined with other plant and network upgrades, will achieve the strategic objectives of the Greater Dublin Strategic Drainage Study (2005), meeting the need for additional wastewater treatment capacity for greater Dublin into the future. The GDD project is a key part of Irish Water’s Water Services Strategic Plan 2015-2040.
