Cork Lower Harbour Main Drainage Project
In 2015, the equivalent of 40,000 wheelie bins of raw sewage was discharged into Cork Harbour every day. We’ve reduced this figure to 10,000 by building a wastewater treatment plant in Shanbally as well as repairing and extending the sewer network to connect more harbour areas to the plant. Irish Water are moving a step closer to our goal of treating the remaining 10,000 wheelie bins of sewage by installing the Cobh to Monkstown Estuary Crossing and continuing the Cobh Town Networks Contract.

About this project
The Cork Lower Harbour Main Drainage Project aims to provide enhanced wastewater treatment through the development of a new wastewater treatment plant at Shanbally, Co. Cork. The project is important in terms of protecting the environment, facilitating economic development and providing for a growing population.
The plant will serve the areas of Cobh, Carrigaline, Crosshaven, Passage West/Monkstown (including Glenbrook) and Ringaskiddy (including Shanbally & Coolmore).
What is involved?
The Cork Lower Harbour Main Drainage Project consists of:
- A new Wastewater Treatment Plant (WwTP)
- 15 new pumping stations
- Upgrading of 4 existing pumping stations
- Approximately 30km of new sewers
- A drilled crossing under the estuary
The raw sewage from Cobh, Passage West, Glenbrook, Monkstown, Carrigaline, Ringaskiddy and Shanbally will be collected into new pipes and redirected to a new WwTP plant at Shanbally. The treated wastewater will then be safely discharged into the estuary via an existing pipeline near Dog Nose Point.
