Project Background

An in-depth study was ordered by the Dublin Region Local Authorities in 2005 to evaluate all wastewater treatment infrastructure in the Greater Dublin Area (GDA).

The aim was to implement a strategy that would meet future wastewater treatment requirements which would allow for growth in both population and industry.

The key points from the study were:

  • To expand all wastewater treatment plants in the GDA to their maximum capacities to ensure wastewater infrastructure in the Dublin region could support future development.
  • To build a new regional wastewater treatment facility in North Dublin that would treat wastewater form the GDA to a high standard, meeting National and EU Directives and Regulations for water quality.

Dublin Region Local Authorities reviewed the study and established projects to implement and deliver the strategy. The Greater Dublin Drainage Project was set up to deliver the regional wastewater facility in North Dublin. The Ringsend Wastewater Treatment Plant Upgrade Project was set up to deliver the expansion works required at the largest plant in the GDA at Ringsend, which has provided wastewater treatment since 1906.

Dublin City Council applied to An Bord Pleanála and in 2012 received permission to carry out the recommended upgrade and expansion works at the plant to maximise its capacity. Permission was also granted to construct a 9km undersea tunnel designed to relocate treated wastewater from the plant out into Dublin Bay.

In January 2014, we assumed responsibility for the provision of public water services, which included the transfer of responsibility for the Ringsend Wastewater Treatment Plant from Dublin City Council. Since taking on this responsibility, we have completed thorough reviews and evaluations of the elements of the project and we are now proposing an alternative solution within a revised project. See our alternative solution here.

Irish Water is currently seeking feedback on a preferred site for a Regional Biosolids Storage Facility (RBSF) for greater Dublin including parts of Kildare, Meath and Wicklow. The preferred site at Newtown/Kilshane, Dublin 11 will serve Ringsend along with other key infrastructure in the Dublin Region. Details of the public consultation process and Irish Water’s proposed site for this facility, when confirmed, will be included in the planning application for the upgrade to the Ringsend plant. For further details on how to get involved in this public consultation or more details on the Regional Biosolids Storage Facility please visit our Biosolids section.
