Under this design, build and operate (DBO) contract Murphy are delivering a major upgrade Lee Road Water Treatment which accounts for 70% of the water supply in the city of Cork. The project entails:
Replacement of the existing facility with a newly constructed and commissioned 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 water treatment plant site has experienced flooding in the past. The design solution to be delivered by Murphy will deliver a state of the art treatment facility while raising the site by 2 metres to protect it against flooding during extreme weather events. This will ensure that reliability and performance are maintained under all conditions.
