Untreated raw sewage has been discharging directly into the lower harbour for decades. Wastewater is collected from homes and businesses across the lower harbour area and undergoes no treatment before being discharged into the sea. This practice is in breach of EU regulations. We are addressing this issue with a long-term investment in wastewater in Cork.

Cobh to Monkstown Estuary Crossing Contract

Irish Water has today awarded the contract for the design and construction of the Cobh to Monkstown Estuary Crossing pipelines to O’Connor Utilities Limited. This will move us a step closer to our goal of treating the equivalent of 40,000 wheelie bins of raw sewage flowing into the harbour by the end of 2021.
