Due to aging chemical feed equipment at Renewable Water Resources’ Georges Creek WRRF, Harper was tasked with demolishing and removing existing equipment, associated piping, and storage tanks. Following demolition, Harper installed six new peristaltic metering pumps located in the Chemical building, as well as four new 8,000+ gallon FRP Tanks. Following completion of this work, Harper was awarded additional similar work at the facilities’ Biosolids Building, which included the addition of a second, larger centrifuge to their existing system. This new centrifuge significantly boosts the production capacity at the plant. Harper’s scope of work for the Centrifuge and Polymer upgrade at Georges Creek included installing a new centrifuge, procured by the owner, demolishing the old conveyor and installation a new conveyor, implementing a polymer feed system, installing new piping, new electrical systems, instrumentation, and controls, and providing the necessary services to ensure a fully functional and safe system.
INNOVATIVE METHODS
While the two centrifuges do not operate simultaneously, the new system enables continuous operation even when one centrifuge undergoes maintenance. Harper encountered several challenges during the project but successfully addressed them through teamwork and ongoing communication, which built trust and left a positive impression with Renewable Water. Harper consistently met project schedules and achieved profitable outcomes overall.
