Cork City Water Supply - Western Trunk Watermain

Irish Water is progressing with significant upgrades to the water network across Cork City.

Irish Water, 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 Irish Water.

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.

Frequently Asked Questions

What are the working hours?
Monday to Friday, 8am to 6pm.

Will access to the Lee Fields carpark be affected during the works?
No, there will be no access restrictions to the carpark during the works.

What will be done with topsoil removed as part of preparatory works?
Topsoil will be temporarily stored within the works area and will be used to reinstate the area following installation of the pipeline.

How will the works area be secured?
All excavated areas will be securely fenced off.

Will trees need to be cut down?
No, tree removal will not be required as part of these works. Minor branch cutting works were completed in early June to ensure a safe working space for works. A survey was carried out by a qualified Ecologist who determined that this activity falls under the exemption described in Section 40 (2) (e) of the Wildlife Act (exemption from the prohibition on vegetation cutting in the course of road or other construction works).

What was done with the mulch from the cut branches?
Mulch was given to Field of Dreams / Down Syndrome Cork at the Clash Road as part of their raised beds and vegetable garden projects.

Will the pedestrian walkway along the Lee Fields be affected?
No, the works will not have any impact on the pedestrian walkway running along the Lee Fields.

How will the excavated areas be reinstated following completion of works?
The area will be topsoiled using the original topsoil and seeded back to grass. This will be completed by the end of September 2021. Full reinstatement with established grass regrowth is expected in Spring 2022.
