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.
