Nenagh Water Conservation & Wastewater Network Project

Water Supply Project

This €17 million Ervia combined infrastructure project is needed to upgrade the water and wastewater networks in Nenagh and to also bring gas to the town for the first time.

Ervia is undertaking this project in Nenagh to bring gas to the town for the first time. To ensure efficiency, reduce costs and to minimise disruption to the local community, the water and wastewater systems are also being upgraded at the same time. This is one of the largest combined capital projects being undertaken in Ireland and will benefit residents and businesses within the town and surrounding areas.

Upgrading the existing water supply network in Nenagh will reduce service disruptions and water leakage and will also with improve the water pressure. Replacing aging sections of the wastewater network will lead to reduced odour and flooding issues in the town.
