Arklow Wastewater Treatment Plant Officially Launched
A major milestone in Irish environmental and infrastructure development was reached today with the official opening of the €139 million Arklow Wastewater Treatment Plant. Taoiseach Micheál Martin and Minister for Housing, Local Government and Heritage, James Browne, were on hand to mark the occasion, celebrating the long-awaited end to raw sewage discharges into the Avoca River.
The new state-of-the-art facility brings Arklow in line with modern environmental standards and unlocks significant potential for housing and commercial development in the region. Until now, Arklow was one of 50 locations identified by the Environmental Protection Agency (EPA) where untreated wastewater flowed directly into rivers, lakes, or the sea, a practice considered unacceptable in a developed country.
Since Uisce Éireann (formerly Irish Water) was established in 2013, 85% of those locations have seen raw sewage discharges eliminated, with ongoing works at 41 of the 50 sites and plans in place to address the remaining nine.
Construction of the Arklow plant began in 2021 after decades of delays due to planning and legal hurdles. Despite the long wait, the project has been delivered both ahead of schedule by six months and within budget.
At the opening, Taoiseach Micheál Martin described the development as a crucial piece of national infrastructure.
“Strategic investments like this are essential to meeting housing demand while also protecting the environment. This facility not only addresses a long-standing environmental issue but also creates a foundation for Arklow’s future growth,” he said.
The plant is built to serve 24,000 people, with expansion capacity for up to 36,000.
Beyond its environmental and developmental impact, the facility has also been recognised for its architectural excellence. The plant received the prestigious Downes Medal from the Architectural Association of Ireland (AAI), awarded for outstanding architectural merit, a rare honour for an industrial building.
Minister James Browne highlighted the project’s broader significance, calling it;
“A transformation for the community. This facility protects the Avoca River, elevates it as a local amenity, and paves the way for new homes and businesses, helping Arklow thrive.”
Niall Gleeson, CEO of Uisce Éireann, emphasised the importance of collaboration in achieving this success.
“This project reflects what can be done when public agencies work in step with private industry leaders like Ward and Burke Construction. It’s a clear example of delivering world-class infrastructure that meets community needs and supports the Government’s housing goals.”
Local Councillor Peir Leonard spoke about the opening, saying;
“This is a day many of us have waited a long time for. I want to thank everyone who kept the pressure on to make this happen, along with the EU’s stronger environmental legislation, which played a crucial role in delivering this vital infrastructure in our lifetime.”
“I’m thinking especially today of Cllr Vincent McElheron and Cllr Tom Clandillon—like myself, they lived beside the river and understood deeply the importance of restoring it.”
“While there’s still much to do, particularly the remediation of the Avoca Mines and the development of treatment plants in Avoca and Aughrim, we are undoubtedly moving in the right direction. I’m excited for the future, watching our river and beaches come back to life, and seeing future generations enjoy them as we once did.”
The Arklow Wastewater Treatment Plant is now fully operational and stands as a long-overdue and highly significant development that not only resolves a long-standing environmental issue but also sets the stage for future prosperity in the region.
