Last week Cork City Council said council crews would be undertaking an "emergency excavation" at Upper Mount View near Kevin O’Leary Centra, to repair the main wastewater sewer which was "blocked by an unidentified illegal discharge of concrete".

The council said the inbound lane of the South Douglas Road would be closed between Ashdale Park and Loretto Park and that traffic management would be in place while the works are being conducted.

Survey works were carried out last week before the excavation works commenced on Friday.

The road was due to be reinstated by Sunday evening, however, works stretched into this week due to the extent of the blockage.

The council said it had hoped to “avoid working within the footpath, and in proximity to existing services under it” but this was not possible as it was found that the blockage extended into that area.

In a statement to The Echo earlier this week, the council said once the works are complete, a subsequent pipe survey and investigation will be undertaken “to attempt to identify the source of the concrete”.
