Work Continues To Replace Corroded Underwater Pipework In Cork

Works are ongoing to repair a pair of large diameter iron non-return flap valves, located at the quay wall on the Marina, near the Atlantic Pond in Cork.

The dual valving system dates back to the late 1960s and permits flow of water from the Atlantic Pond during low tides, while preventing tidal inflow during high tides.

Following an underwater inspection by our specialist marine contractor, involving a sub-aqua dive team, with additional surface support from Cork City Council drainage crews, it emerged that significant repairs were required to both valves.


Phase 1 of the repairs, involving the bespoke refabrication and replacement of the hinging mechanism to the inner valve, is almost complete. Reinstallation of the valve have been completed.

Phase 2 of the repairs, involving the procurement and installation of a new valve, replacement of a section of corroded underwater pipework and localised quay wall repairs, at the site of the external valve are also being progressed, in partnership with our specialist marine contractors. This phase of the works is intended to provide the necessary redundancy in the valving, to mitigate against similar future issues.
