Uisce Éireann’s concerted efforts to improve water supply for customers in Clonmel is continuing as crews are working to replace old water mains in the town and undertaking improvement works at Glenary and Poulavanogue Treatment Plants.   

Work has been taking place in the areas of Western Park, Connolly Park, Western Road and Albert Street to replace 900 metres of aged cast iron water mains with new modern pipes along with the replacement of backyard services enhancing water quality and addressing the loss of treated drinking water into the ground. 

Update on Works to Address Water Supply Challenges 

Replacing water mains will over time enhance water quality, but Uisce Éireann acknowledges the wider impact of supply issues on businesses and residents in Clonmel. A cross-functional working group has been established to identify and prioritise key solutions and ensure these are delivered as quickly as possible. Uisce Éireann has dedicated considerable efforts to address the challenges identified through operational interventions and capital upgrades. 

In the last six months, Uisce Éireann has carried out several remedial and improvement works at Glenary Water Treatment Plant and undertaken a number of operational improvements at Poulavanogue Water Treatment Plant. As a result of these interventions and the ongoing work, the number of unplanned interruptions and water quality issues in the Clonmel area has reduced considerably, and local customers are benefiting from a more secure, resilient supply. As further works are complete, the risk of outages and Boil Water Notices will decrease. 

Longer-term, Uisce Éireann has committed to significant investment in the Clonmel area by the end of 2026 to deliver a more robust, resilient water supply which will include new sources, upgraded treatment facilities, 24-hours’ storage and an upgraded network. This will ensure capacity for domestic growth and development for the next 10-plus years. 

Uisce Éireann endeavours to directly notify residents and businesses at least 48 hours in advance of any planned interruptions to the water supply. Areas of works are limited to short sections to minimise impact on customers. Traffic management in the form of a stop/go system is in place where water mains are being constructed but the community can be assured that local and emergency traffic will be maintained at all times. Interruptions to supply as a result of burst water mains or treatment plant interruptions may result in water outages which are unplanned and cannot be communicated in advance. Uisce Éireann aim to update our services and supply map as soon as details of a water outage is notified along with an update on restoration times. 

Uisce Éireann also understands that some customers have different needs when it comes to using our water services and communicating with us. Uisce Éireann has a special service for those who are registered as critically dependent on water. You can register yourself or somebody in your home as a vulnerable customer by calling 1800 278 278, visiting our vulnerable customer section or emailing Our customer team will proactively update registered vulnerable customers in the event of an outage.
