Cork City Water Supply - Eastern Strategic Trunk Watermain

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

Irish Water, working in partnership with Cork City Council, is working to improve the security of water supply across Cork City through the delivery of three projects. Farrans Construction is delivering these three projects on behalf of Irish Water, with the works expected to commence in the coming months.

Irish Water is upgrading Cork City trunk watermains to increase security of supply and reduce leakage of large strategic mains in Cork City.

News and Updates

Sundays Well Road

A road closure extension has been granted from Wednesday 01 September to Friday 01 October. Works will be carried out this weekend (Saturday 18th & Sunday 19th) and next week between Buxton Hill & Convent Avenue. Local and emergency access will be maintained at all times throughout the road closure.

Area 1 - Works on a culvert crossing will begin on Monday 20th September until Friday 1st October. There will be no access to the Sunday’s Well Road via the North Mall.

Area 2 - Works will commence from Buxton Hill towards Convent Avenue/Aagrah Indian Restaurant on the Sundays Well Road on Monday 20th September until Friday 1st October. There will be a full road closure in place along this section of works.

Local access between these sites will be via Sundays Well Avenue which is currently a one-way system. Traffic management will be in place facilitating vehicular movements 24/7 for the duration of these coinciding works to allow local access in both directions.

What is involved as part of this project?

As part of this project, Irish Water will:

  • Replace and upsize where required 2.4km of various sized large diameter trunk mains between Camden Quay and Shanakiel Reservoir.

What are the benefits of this project?

  • Provide a secure and reliable water supply to Cork City.
  • Reduced leaks as the replacement of water mains and service connections will eliminate existing leaks and reduce the amount of clean drinking water lost into the ground.
