Tullow Water Mains Replacement
Uisce Éireann has replaced aged water mains in Tullow Town Centre in order to provide a more reliable water supply, reduce high levels of leakage and improve water quality.
The works involved the replacement of over 2.1km of aged cast iron water mains with new modern pipes. The programme which replaced the water mains in Tullow Town Centre commenced in February 2025.
These works were being carried out as part of Uisce Éireann’s National Leakage Reduction Programme.
The section of works took place along Church Street, Bridge Street, Market Square, Mill Street, Bishop Street, Old Chapel Lane, John Street, The Course/ Crosskeys and Mullawn.
The works also involved laying new water service connections from the public water main in the road to customers’ property boundaries and connecting it to the customers’ water supply.
The works were carried out on behalf of Uisce Éireann by Shareridge and were completed by November 2025.
To minimise disruption, a phased approach with areas of works limited to short sections were adopted for delivery of this project.
The phases to facilitate works were as follows, with works commencing in Phase 1;
| Phase 1 | Mill Street Lower | March | 2 weeks | Road closure |
| Phase 1 | Mill Street Upper | March /April | 2 weeks | Road closure |
| Phase 2 | Church Street night works only | April | 2 weeks | Stop and go traffic management |
| Phase 2 | The Course/Crosskeys | April | 2 weeks | Stop and go traffic management |
| Phase 2 | Church Street – night works only | April/May | 3 weeks | Stop and go traffic management |
| Phase 2 | Old Chapel Lane | May/June | 2 weeks | Road closure |
| Phase 2 | Bishops Street | June | 2 weeks | Road closure |
| Phase 3 | John’s Street | June /July | 2 weeks | Road closure |
| Phase 3 | Course/Crosskeys continuing onto Chapel Lane, Mill Street and Mullawn | July | 2 weeks | Stop and go traffic management |

What are the benefits of the works?
The benefits of these leakage reduction works include:
- Reliable Water Supply – Replacement of problematic water mains and service connections will reduce the instances of bursts and interruptions to the water supply reducing disruption for homes and businesses in the area.
- Reduced Leaks – Replacement of problematic water mains and service connections will eliminate existing leaks and reduce the amount of clean drinking water lost into the ground.
- Improved Water Quality – Removing existing old cast iron and lead from the public water network and replacing them with new pipes will reduce the risk of contamination.
- Improved Operation and Maintenance – These works will deliver efficiencies including cost savings by providing improved water network operation that will require less maintenance in the future.
