Major upgrade to the Ringsend Wastewater Treatment Plant commences
Ringsend is the largest wastewater treatment plant in Ireland
Irish Water is today commencing work on an €80 million, 400,000 population equivalent upgrade to the Ringsend Wastewater Treatment Plant. Ringsend is the largest wastewater treatment plant in Ireland and was built to treat the wastewater for the equivalent of 1.64 million people. Currently the plant services over 40% of the national population and is treating wastewater for the equivalent of 1.9 million people.
This upgrade will take approximately two years to construct and will accommodate the current demand, support planned housing and economic growth in the Dublin Region and will improve the quality of the treated wastewater discharged to the Liffey estuary.
Currently, the plant serves the Greater Dublin Area including the city centre and stretching to suburban areas such as Dalkey, Rathcoole, Clondalkin, Blanchardstown/Mulhuddart, Dublin Airport and Howth, as well as parts of Meath such as Dunboyne, Clonee and Ashbourne.
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.
Lord Mayor of Dublin City, Mícheál MacDonncha said: “With the CSO predicting the population of the Greater Dublin Area to grow by 1% per year over the next ten to fifteen 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.”
“This is a priority project for Irish Water and is vital for future social and economic development in Dublin, for public health and for improving the waters and ecology of Dublin Bay."
Minister for Housing, Planning and Local Government, Eoghan Murphy, TD said: “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.”
Managing Director for Irish Water, Jerry Grant said: “This is a priority project for Irish Water and is vital for future social and economic development in Dublin, for public health and for improving the waters and ecology of Dublin Bay. The work starting today will add a further 400,000 population equivalent treatment capacity to the plant. We will be submitting a planning application to An Bord Pleanála in the Spring of this year to progress the further upgrade to the plant to support the wastewater needs of a population equivalent of 2.4 million, in the most cost effective, environmentally sensitive and timely manner.
AGS technology was identified by Irish Water as ideally suited to deployment at Ringsend. We are already using this technology in Shanbally and Clonakilty Wastewater treatment plant and have proven its suitability for the Ringsend Wastewater Treatment Plant.
Given the economic projections for growth for the Greater Dublin Area, Irish Water will be rolling out a number of major investments in both water supply and wastewater for the region of which the Ringsend Wastewater Treatment Plant Upgrade Project is one of the most important. We will also be seeking permission shortly for the Greater Dublin Drainage Scheme, with a new wastewater treatment plant in Clonshaugh, which will be needed from 2025 to enable the northern & north western environs of the city to continue to grow into the future.”
In December 2017, 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.
