Cork City Water Supply - Western Trunk Watermain

Uisce Éireann is progressing with significant upgrades to the water network across Cork City.

Uisce Éireann, in partnership with Cork City Council, is working to improve the security of water supply across Cork City through the delivery of three projects as part of the Cork City Water Supply Scheme. Farrans Construction is delivering these three projects on behalf of Uisce Éireann.

Western Trunk Watermain
Eastern Strategic Trunk Watermain
Shanakiel Watermains Upgrades

We are upgrading Cork City trunk watermains to increase security of supply and reduce leakage of large strategic mains in Cork City.

Western Trunk Watermain

This project involves the construction of a 5.5km link between the Cork City Water Supply Scheme and the Cork Harbour and City Water Supply Scheme, as supplied from Inniscarra Water Treatment Plant. This watermain will provide additional water supply capacity to Cork City by providing a strategic connection between the water supply schemes and will provide necessary headroom, to facilitate growth and also increase security of supply.


What is involved as part of this project?

As part of this project Uisce Éireann will:

  • Connect to an existing 1500mm diameter city and harbour trunk (city ring) main at Curraheen.
  • Construct a new 5.5 km trunk main connecting to the Cork City WSS at Lee Road Water Treatment Plant.
  • This project will include a crossing of the River Lee and critical road arteries into Cork City.
  • Connect to the Lee Road Water Treatment Plant and new pumping regime and into existing network.

What are the benefits of this project?

The works carried out as part of this project will:

  • Provide security of supply to Cork City
  • Provide necessary additional water supply capacity
  • Facilitate growth and development of Cork City
