About this project

Overview

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).

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.
