The once-in-a-generation investment will provide the capacity to support the town’s future growth, safeguard the local environment, and protect the Nenagh River for decades to come.

With planning permission now secured, Uisce Éireann will move forward with finalising design and preparing for the construction phase of the project.

Esther White, Uisce Éireann Portfolio Manager, said:

“We’re delighted to forge ahead with this much-needed project for the community in Nenagh. This major investment will expand capacity at the wastewater treatment plant from 12,000 to 19,800 population equivalent (pe), ensuring the town and its environs have the vital wastewater infrastructure to grow and thrive.

“It will support to unlock the towns growth, which is key to the delivery of new homes and businesses, while also protecting the local environment and enhancing the area for everyone".

EPS will deliver the project on Uisce Éireann’s behalf.

The Nenagh project is part of Uisce Éireann’s ongoing multimillion euro investment in upgrading the wastewater infrastructure across County Tipperary, which includes:

  • recently completed projects in Newport, Ballina, and Cahir;
  • ongoing upgrade at Fethard;
  • site investigations on the network in Thurles;
  • and planning under review for Grangemockler and Kilsheelan.
