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


  • Improve the security of drinking water quality for residents and businesses in Co. Leitrim
  • Improve disinfection systems and standards.
  • Future proofing the security of supplies.
  • Provide improved control of the systems.
  • Ensure continued compliance with Drinking Water Quality Regulations.
