Limerick Disinfection Programme

National Disinfection Programme

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

About this project

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

Disinfection systems at 19 plants have been upgraded and standardised. We have also finished operational upgrades to public water supplies and pumping stations.

These sites include: Rockhill PS, Anglesboro, Athlacca Pump Station, Ballingarry Spring, Moloneys Pump Station, Ballygrennan Borehole, Finn's Borehole (Bruff), Bruree Pump Station, Caherconlish Pump Station, Ballyagran Pump Station, Cooga Spring WTP, Fadamore WTP, Glenosheen WTP, Herbertstown Pump Station, Carrigmore WTP, Clouncagh and Hospital, Oola WTP and Martinstown WTP

What was involved

The programme involved assessing the condition and performance of all the sites. We then determined the disinfection systems that needed to be upgraded.

Works at the plants included upgrades to the:

  • Chemical storage and dosing infrastructure
  • Chlorine contact time provision systems
  • Disinfection system using Ultra Violet (UV) where required
  • Monitoring instrumentation systems
  • Control, telemetry and automation processes


The upgrade works carried out as part of this project will:

  • Improved the security of drinking water for residents and businesses
  • Improved disinfection systems and standards
  • Future-proofed the security of supplies
  • Provided improved control of the systems
  • Ensured continued compliance with Drinking Water Quality Regulations
