Coachford Wastewater Treatment Plant

Wastewater Project

Irish Water, working in partnership with Cork County Council, is constructing a new wastewater treatment plant in Coachford, Co. Cork. EPS Group Limited has been commissioned to deliver this project on our behalf. This project is part of a €27 million investment in the Cork Mid-West area and will include the construction of a new wastewater treatment plant and associated infrastructure in this area. This will improve the wastewater treatment quality and capacity and ensure compliance with wastewater discharge regulations.
