Carlow Disinfection Programme

National Disinfection Programme

The National Disinfection Programme ensures Carlow will continue to have safe and secure drinking water. We have been working with Carlow County Council to assess the water treatment plants in Carlow.

About this project

AECOM (Murphy Process Engineering ltd.) is working on behalf of Uisce Éireann to deliver the National Disinfection Project across the county.

Disinfection systems at 12 plants are being upgraded and standardised.

These sites include: The Parade (Bangelstown), Royal Oak (Bangelstown), Ballinkillin, Borris, Raheenleigh, Rathvilly, Oak Park (Carlow Town), Sion Cross (Carlow Town), Leighlinbridge, Old Leighlin, Tyllow and Bilboa WTP.

What is involved

The programme involves assessing the condition and performance of all the sites. We then determine the disinfection systems that need to be upgraded.

Works at the plants included upgrades to the:

  • Chemical storage and dosing infrastructure
  • Chlorine contact time provision systems
  • disinfection systems 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:

  • Improve the security of drinking water for residents and businesses
  • Improve disinfection systems and standards
  • Future-proof the security of supplies
  • Provide improved control of the systems
  • Ensure continued compliance with Drinking Water Quality Regulations
