Ending the discharge of untreated sewage into Cork Lower Harbour

Irish Water, in partnership with Cork County Council, is working to end the decades-long practice of discharging untreated sewage into Cork Lower Harbour and clean up the harbour through its investment in the Cork Lower Harbour Main Drainage Project. 

To safely complete these vital works in the Passage West area, it was necessary to temporarily close a 90-metre section of road on the R610 in the vicinity of Passage West library. 

Committed to consulting with the local community 

Due to continued progress and the cooperation and patience of the Passage West residents and businesses, these works are nearing completion and the R610 road will reopen from Saturday 10 November. We would like to reiterate our commitment to working with the local community to minimise the impact of these essential works and would like to thank the people of Passage West, Glenbrook, Monkstown and all the Lower Harbour residents for their ongoing cooperation as we work together to deliver the Cork Lower Harbour Main Drainage Project and end the discharge of raw sewage into the Cork Lower Harbour.

The works on Cork Lower Harbour Main Drainage Project are already having major benefits in terms of protecting the environment and the health of local communities, facilitating economic development and providing for a growing population.

20,000 homes and businesses will be connected to the new scheme

When all Cork Lower Harbour Main Drainage works are complete in 2021, the project will treat all wastewater from Passage West, Monkstown, Ringaskiddy, Crosshaven, Carrigaline, Glenbrook, Shanbally, Coolmore and Cobh. This means 20,000 homes and businesses will be connected to the new scheme and that raw sewage will no longer be discharged into the Harbour. At present, the equivalent of 20,000 wheelie bins of sewage is discharged into the harbour every day.
