Sligo Disinfection Programme

National Disinfection Programme

The National Disinfection Programme ensures Sligo will continue to have safe and secure drinking water. We have worked with Sligo County Council to complete a detailed assessment of the water treatment plants in Sligo.

About this project

Glan Agua Limited has worked on behalf of Uisce Éireann to deliver the National Disinfection Project across the county. The Sligo programme is now complete.

Disinfection systems at 3 plants have been upgraded and standardised.

These sites include: Lough Easkey Regional Water Supply, North Sligo Regional Water Supply and Heapstown Well / Riverstown Water Treatment Plant.
