Information below is relevant until further updates are provided here or on our Supply and Service Updates section
Uisce Éireann is continuing its significant investment in Lismore’s water network, with almost 2.5km of ageing watermains now replaced as part of an ongoing upgrade designed to deliver a more reliable and sustainable water supply for homes and businesses across the town. This work is part of a wider programme in Lismore that will see almost 3km of ageing watermains replaced along Deerpark Road and Lismore Bridge.
The next phase of work will begin in the coming weeks and will involve further upgrades along the N72, from Lady Louisa’s Walk over Lismore Bridge, where the remaining section of almost 0.5km will be replaced, continuing the investment to reduce leakage, improve water quality and strengthen network resilience.
To safely progress to the next stage of commissioning the new infrastructure, customers in Lismore may experience low water pressure or no supply between 3pm and 8pm next Wednesday (28 January 2026). A further planned outage will also be required in the coming weeks, and details of this will be communicated closer to the time. Supply will return gradually once works are complete and the network has time to recharge.
Dave Murphy, Portfolio Manager at Uisce Éireann, said: “We are committed to ensuring Lismore has a more resilient and reliable water supply for the future. By replacing vulnerable sections of ageing mains, we are significantly reducing leakage and strengthening the network for local homes and businesses. We greatly appreciate the community’s patience and cooperation as we carry out these essential works, which will deliver long-term benefits for the town.”

Earlier this year, Uisce Éireann’s Leakage Reduction Programme arrived in Lismore, delivering targeted improvements, including the identification and repair of leaks on the water network in the town, including on the customer-side and key improvements to enhance underground flow control. These works reduced leakage in the area, saving thousands of litres per day and improving the reliability of water supply to our customers.
This project to replace almost 3km of water main is also being delivered as part of Uisce Éireann’s Leakage Reduction Programme which continues to deliver significant benefits to communities across Ireland, including improved water quality, provision of a more resilient and sustainable water supply for customers, and considerable water savings.
The first phase of works will take place along Deerpark Road from its junction with Main Street towards Deerpark North. The second phase will commence in early 2026 along the N72, from Lady Louisa’s Walk over Lismore Bridge.
