Enniscorthy Regional Water Supply Scheme

Uisce Éireann is almost complete works on a €19 million upgrade to the Enniscorthy Regional Water Supply Scheme.

Uisce Éireann is almost complete works on a €19 million upgrade to the Enniscorthy Regional Water Supply Scheme. The project which will benefit over 11,000 consumers, will ensure a reliable and sustainable water supply for Enniscorthy and surrounding areas, as well as allowing for future growth and development. David Walsh Civil Engineering Ltd. is delivering the project on behalf of Uisce Éireann.

The Enniscorthy water supply infrastructure had limited resilience, with deficient intake arrangements and undersized raw water mains, which has led to frequent outages and water quality issues for the Enniscorthy supply. The existing intake area at Clonhaston, which has now been replaced, was subject to flooding/damage on a regular basis and was restricted for operation.

The supply was on the Environmental Protection Agency (EPA) Remedial Action List (RAL), which identifies water supplies that are in need of improvement. As the project is near completion the supply has now been removed from the EPA’s RAL.

• Replacement of the raw water intake at Clonhaston to transfer water from the River Slaney to the Vinegar Hill Water Treatment Plant (WTP).
• Replacement of 2km of interconnecting raw water main.
• Construction of a new pumping station.
• Upgrade of the water treatment facilities at Vinegar Hill WTP.
• Landscaping and all associated site development works.

Ensure a reliable and sustainable water supply for Enniscorthy and the surrounding areas.

• Improve the efficiency of the facility.
• Provide capacity to support future growth and development of Enniscorthy.
• Remove the supply from the EPA's Remedial Action List. The supply was removed from the EPA’s RAL in February 2026.
• Ensure compliance with national and EU regulations relating to the provision of drinking water.

• The scheduled completion date for the project is spring 2026.
