Arklow Wastewater Treatment Plant Recognised with Prestigious Awards

/by

 

AOCA Engineering is proud to announce that the Arklow Wastewater Treatment Plant, a landmark project in which we played a central role, has been recognised with significant national awards for both its environmental and architectural contribution.

The facility has been honoured with the Architectural Association of Ireland’s (AAI) Downes Medal for architectural merit, and has also been shortlisted for the Royal Institute of the Architects of Ireland (RIAI) Public Choice Award 2025. These awards highlight not only the importance of the project in delivering vital infrastructure, but also its innovative approach to design and integration within the community.

A Long-Awaited Solution

For decades, Arklow faced the challenge of untreated wastewater discharges into the Avoca River and the Irish Sea, in breach of environmental legislation. The new plant finally addresses this long-standing issue, bringing an end to the discharge of untreated effluent and safeguarding both public health and the local environment.

Engineering & Architectural Excellence

Constructed on the site of the old Wallboard Factory at Ferrybank, the €139 million plant is designed to serve an initial population equivalent of 24,000, with capacity to expand to 36,000. Beyond its technical capabilities, the project stands out for its architectural design, with striking façades inspired by Arklow’s maritime landscape and features that enhance both sustainability and biodiversity.

The facility incorporates advanced treatment processes, new interceptor sewers, and a long sea outfall for treated wastewater. Energy efficiency has been prioritised, with gravity-led flows, rooftop solar panels, and design elements that minimise operational impact.

A Collaborative Achievement

AOCA Engineering is honoured to have contributed our expertise to this transformative development. The project has been widely recognised as an example of what can be achieved when engineering and architecture work hand in hand to deliver sustainable infrastructure that benefits both the environment and the community.

We congratulate our project partners and all those involved in bringing this milestone achievement to completion.
