Lee Road Water Treatment Plant

Under this design, build and operate (DBO) contract Murphy delivered a major upgrade to Lee Road Water Treatment which accounts for 70% of the water supply Cork city. The project entailed:

• Replacement of the existing facility with a newly constructed and commissioned 40 ML/day capacity water treatment plant.
• Refurbishment and upgrade of existing pumping stations feeding the distribution network.
• An increase in water treatment capacity from 36MLD to 40MLD over an 18 hour period.

Situated beside the River Lee, the existing treatment facility, had experienced flooding in the past. The design solution delivered by Murphy has delivered a state of the art treatment facility while raising the site by 2 metres to protect it against future flooding during extreme weather events. This will ensure that treatment plant reliability and performance are maintained under all such challenging conditions.

The upgraded facility designed and delivered by Murphy includes:

• Reconfigured raw water intake.
• Coagulation, flocculation and clarification system.
• Rapid gravity filters.
• Chemical and UV disinfection.
• Installation of pH correction facilities.
• Washwater and sludge handling facilities.
• New treated water pumping station and refurbishment of existing pumping station.
• EICA infrastructure including PLCs, communication links and SCADA system.
• Flood prevention works.

Upon completion of commissioning and performance testing in 2022, Murphy has operated and maintained this facility and continues to provide technical support to Uisce Eireann during the ongoing operation of the works.
