Irish Water has started work this week on an €80 million, 400,000 population equivalent upgrade to its Ringsend Wastewater Treatment Plant, the largest in Ireland.
Ringsend 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.
The 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 extending out to suburban areas.
The 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.
Minister for Housing, Planning and Local Government, Eoghan Murphy, TD described the upgrade as “a hugely important and modernising step for our national and regional wastewater infrastructure.”
Irish Water will submit 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 the water company as ideally suited to deployment at Ringsend - the utility is already using the technology in Shanbally and Clonakilty Wastewater treatment plant.
Managing Director for Irish Water, Jerry Grant said:
“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.
