Cork City Water Mains Rehabilitation

Water supply project

This €15.8 million investment is needed to improve water supply and quality for homes and businesses in Cork City.

The project will see the large-scale replacement and rehabilitation of over 27km of old, corroded water mains in Cork City and will also reduce water leakage by over 18 million litres of water per week on completion. Existing sections of water mains will be increased and upgrades to service connections will be carried out as part of the project.
