Irish Water, working in partnership with Monaghan County Council, has completed a €6 million modernisation and upgrade of its Castleblayney Wastewater Treatment Plant.
The plant was originally constructed in the 1980s – the mechanical and electrical equipment had exceeded its operational life and required an upgrade. The works will ensure the wastewater treatment plant is fully compliant with EU Urban Wastewater Directives and will bring environmental benefits to the area as well as providing the capacity for future growth.
EPS Group carried out the works on behalf of Irish Water.
This project will bring significant benefits to the area in terms of health, development potential and improved water quality.
The upgraded treatment plant includes a new inlet works, a new sewer from Muckno Pumping Station to the wastewater treatment plant pumping station (which has eliminated the need for the Muckno Pumping Station) and associated infrastructure which has been designed to improve the standard of wastewater treatment and accommodate the local population into the future.
The project forms part of Irish Water’s investment plan which involves a €5.5 billion investment in capital spending on drinking water and wastewater quality and capacity and new infrastructure up to 2021. Works have been prioritised to address the most critical issues in line with commitments outlined in Irish Water’s Business Plan.
