Irish Water has started an €80 million upgrade to its Ringsend wastewater treatment plant.
It is expected that an extra 400,000 people will be served by the plant after its redevelopment.
Wastewater from Dublin has been treated in Ringsend since 1906. It is the largest wastewater treatment plant in Ireland, and services more than 40% of the national population.
Currently, the plant serves the Greater Dublin Area including Dalkey, Rathcoole, Clondalkin, Blanchardstown/Mulhuddart, Dublin Airport, Howth and the city centre, as well as parts of Meath such as Dunboyne, Clonee and Ashbourne.
The upgrade will take approximately two years to construct and will support planned housing and economic growth in the Dublin region.
It will also improve the quality of the treated wastewater discharged to the Liffey estuary.
This capacity upgrade is one part of an overall investment of €400 million by Irish Water in the Ringsend wastewater treatment plant upgrade project.
Subject to planning permission, the overall upgrade project will enable full treatment of wastewater for the equivalent of 2.4 million people, meeting all foreseeable development needs to at least 2025.
The Lord Mayor of Dublin, Micheal MacDonncha, said it is important that Dublin can sustain growth: “With the CSO predicting the population of the Greater Dublin Area to grow by 1% per year over the next ten to 15 years, it is vital our infrastructure keeps up with that growth.
“This investment will enable future housing and commercial development and help ensure Dublin is able to sustain continued growth.”
Minister for Housing, Planning and Local Government, Eoghan Murphy, welcomed the commencement of the upgrade, saying: “This is a hugely important and modernising step for our national and regional wastewater infrastructure.
“This investment is preparing our capital city for future growth. It will ensure that the highest treatment standards are being deployed and utilised in Dublin, that we are preparing for future housing, population and economic growth and that we meet the stringent requirements of the EU’s wastewater treatment directives.”
Last December, Irish Water awarded the capacity upgrade contract to Veolia Water Ireland Ltd & PJ Hegarty & Sons DC Joint Venture for the construction of this phase of the upgrade.
