Potential odour during essential maintenance at Ringsend

Irish Water is carrying out essential cleaning works at the Ringsend Wastewater Treatment Plant to deal with current odour issues and reduce the risk of odours from debris over the summer months.

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.

Key points from the study

  • 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.

In April 2019, An Bord Pleanála granted permission for the works required to facilitate the use of Aerobic Granular Sludge (AGS) technology, to omit the previously permitted long sea outfall tunnel and to upgrade the sludge treatment facilities at Ringsend, Dublin 4, and to provide for a Regional Biosolids Storage Facility in Newtown, Dublin 11. This further upgrade of the Ringsend Wastewater Treatment Plant will enable future population growth and ensure the plant operates to the highest possible environmental standards.  For further details on this planning application please visit our Environment and Planning section.
