Due to rapid growth, the plant needed to be expanded to a treatment capacity from 13.5 MGD to 22.5 MGD. Design included upgrade of the raw water pump facility, new carbon feed system, raw water metering vault, flash mix reactor, two 4.5 MGD process trains, upgrades to the waste handling facilities, expansion of the pipe gallery building, high service water line, new on-site 2000 lbs./day hypochlorous acid generation system, a new clearwell, a new high service pump station, and upgrade of existing feed system. A significant accomplishment of the project was the replacement of the gaseous chlorine as the primary disinfectant with a non-hazardous hypochlorous acid generation system.
