Roscommon Main Drainage Scheme

Irish Water is progressing works to upgrade the sewer network in Roscommon Town.

Irish Water, working in partnership with Roscommon County Council, has commenced works on the Roscommon Main Drainage Scheme project to safeguard the environment and provide for future growth and development in the town. This project represents a further step in the continued delivery of improvements to the wastewater network in Roscommon.

When completed, the €20 million project will reduce the risk of sewer flooding in Roscommon Town and improve water quality in the River Jiggy and River Hind. It will also increase the capacity of the sewer network, providing a platform for future population growth and economic development.
