Uisce Éireann has been granted planning permission for a €49 million upgrade to the Nenagh Wastewater Treatment Plant, a project expected to significantly reduce pollution risks and protect the Nenagh River in County Tipperary.

The investment will modernise the existing treatment systems and expand capacity from 12,000 to 19,800 population equivalent (pe). According to Uisce Éireann, the improvements will ensure that wastewater from homes and businesses in the town is treated to a much higher standard before being released back into the environment.

Esther White, Uisce Éireann Portfolio Manager, said the project represents a major step forward in protecting local waterways.

“We are delighted to move ahead with this much-needed project for the community in Nenagh. It will safeguard the Nenagh River, improve water quality, and provide the capacity the town needs to grow sustainably,” she said.

“It will also help facilitate the delivery of new housing and business developments while supporting long-term environmental protection.”

The utility said the upgrade will also reduce the risk of untreated discharges during heavy rainfall, a problem that has affected older wastewater networks in several towns across the country.

EPS has been appointed to deliver the project on behalf of Uisce Éireann. Design work will now be finalised before construction begins.

The Nenagh upgrade is part of a wider programme of investment in wastewater infrastructure across County Tipperary. Uisce Éireann has recently completed projects in Newport, Ballina, and Cahir, while works continue in Fethard and planning is under way for improvements in Thurles, Grangemockler, and Kilsheelan.

Uisce Éireann said its overall investment strategy aims to protect water quality, support future development, and ensure compliance with environmental standards across Ireland.
