Mallow Sewer Network Upgrade

Irish Water is progressing with upgrades to the sewer network to eliminate nine sewer overflows and improve water quality.

Mallow Sewerage Network Upgrade Project

Irish Water, working in partnership with Cork County Council, is progressing with upgrades to the sewer network in Mallow, Co. Cork. The project is expected to be completed in spring 2023 and includes:

  • Upgrading the sewer network through the removal of 9 Combined Sewer Overflows (CSOs); and
