Described as a “once-in-a-generation investment”, it aims to provide the capacity to support the town’s future growth, safeguard the local environment, and protect the Nenagh River for decades to come, according to the company. With planning permission now secured, Uisce Éireann will move forward with finalising design and preparing for the construction phase of the project.

Uisce Éireann portfolio manager Esther White said: “This major investment will expand capacity at the wastewater treatment plant from 12,000 to 19,800 population equivalent, 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 this project on Uisce Éireann’s behalf. Works will include the construction of a new inlet pumping station, modernisation of treatment processes, and the installation of new stormwater holding tanks with a total volume of 3,000 cubic meters.

The works will also include a new ferric dosing plant, sludge import system with centrifuges, and the refurbishment of the control building, installation of a new ESB substation and permanent site generator, and site-wide flood protection and attenuation.

The Nenagh project is part of Uisce Éireann’s ongoing multi-million euro investment in upgrading the wastewater infrastructure across County Tipperary, including recently completed projects in Newport, Ballina, and Cahir, ongoing upgrades at Fethard, site investigations on the network in Thurles, as well as planning under review for Grangemockler and Kilsheelan.

Uisce Éireann said it is responsible for delivering public drinking water and wastewater services for the people of Ireland.

“We are committed to enabling communities to thrive by continuously upgrading and developing critical infrastructure to support sustainable growth and development, providing safe drinking water, and enhancing the environment,” said a spokesperson.
