Uisce Éireann is proud to announce that the Arklow Wastewater Treatment Plant has been shortlisted for the prestigious 2025 Royal Institute of Architects of Ireland (RIAI) Public Choice Award. This recognition celebrates the plant's innovative design and its transformative impact on the Arklow community. 

Designed by Clancy Moore Architects in collaboration with Ayesa Engineers, the €139 million facility marks a significant milestone as Ireland's first wastewater treatment plant to integrate architectural design from inception.  

Michael Tinsley, Senior Portfolio Manager with Uisce Éireann, said “Previously, Arklow faced environmental challenges due to the absence of wastewater infrastructure, leading to untreated sewage entering the Avoca River. The completion of this project has not only addressed these issues but has also reshaped the town’s visual identity, blending architecture with the natural beauty of the Avoca River and its surroundings.” 

The plant's distinctive mint-green structures have garnered attention for their aesthetic appeal and functionality. Features such as bat-friendly louvres and an on-site solar farm underscore the project's commitment to sustainability.  

The Architectural Association of Ireland recently awarded the plant its highest honour, the Downes Medal, for ‘outstanding architectural merit’. 

The RIAI Public Choice Award is unique in that it is determined by public vote, offering communities an opportunity to celebrate architectural excellence that enhances daily life. The Arklow plant secured one of 48 coveted spots on the shortlist. Uisce Éireann encourages all residents of Wicklow and beyond to support the Arklow Wastewater Treatment Plant by casting their vote.
