With planning permission now secured, construction is set to begin in later 2026, with Stantec and Ward & Burke Construction Ltd. collaboratively carrying out the works on behalf of Uisce Éireann.

The new treatment plant is a sustainable, nature-based wastewater treatment system which is designed to look and function as a natural wetland. It provides a natural treatment solution that will significantly reduce energy consumption and carbon emissions when compared with the conventional wastewater treatment process, while also acting as a carbon sink, helping to offset emissions from other sources. Uisce Éireannsaid the wastewater infrastructure upgrade will also enable sustainable local growth.

The constructed wetland will contain vegetated ponds planted with native species that will enhance local biodiversity. Due to the limited above ground infrastructure the ponds have minimal visual impact on the existing landscape.

The delivery of the project includes:

David McLoone, Uisce Éireann Programme Manager, said: 

“We are delighted that we can now forge ahead with the development of this sustainable wastewater infrastructure in Grangemockler. This project will play a key role in protecting the local environment, including the Currasilla Upper stream, that is within the lower River Suir Special Area of Conservation (SAC), while also promoting local biodiversity.”

The project is part of Uisce Éireann’s ongoing multimillion euro investment in upgrading the wastewater infrastructure across County Tipperary, including recently completed projects in Newport, Ballina, and Cahir; as well as ongoing upgrades at Fethard, Nenagh and Kilsheelan where planning permission was recently granted. Site investigations have also been completed on the network upgrade in Thurles.
