What was involved

​The programme involved assessing the condition and performance of all the sites. We then determined the disinfection systems needed 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) barriers where required
  • Monitoring instrumentation systems
  • Control, telemetry and automation processes


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

  • Improved the security of drinking water for residents and businesses
  • Eliminated the risk of boil water notices
  • 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
