Irish Water has completed the installation of two pipes using horizontal directional drilling (HDD) at the Cork Lower Harbour Main Drainage Project.
In partnership with Cork County Council, Irish Water is working to end the practice of discharging raw sewerage directly into Cork Lower Harbour with its drainage project.
Last week, Irish Water completed the sewer pipe installation in the second and final drilled bore that extended more than 1 km under the Lee Estuary between Cobh and Monkstown.
Irish Water said this landmark engineering feat includes two of the longest HDD’s ever carried out in Ireland.
Cork Lower Harbour Main Drainage Project Manager Déaglán Healy said the team is delighted to have successfully and safely completed the drill and installation works for the contract.
“We’d like to thank [the local community] for working with our contractor for the works, O’Connor Utilities, who have worked tirelessly, in partnership with Long O’Donnell, Nicholas O’Dwyer and our own Irish Water project team, to ensure the safe completion of these works while minimising the impact on the local community as much as possible,” said Mr Healy.
The successful installation completes the works under the estuary and creates the vital connection between Cobh and Monkstown.
The new connection will allow the raw sewage from Cobh to be transferred for treatment, following completion of Cobh Town Networks’ contracts in 2021.
