This wastewater treatment facility expansion doubles the capacity to serve the rapidly growing surrounding areas. The expansion was accomplished by constructing two new treatment trains of 3.0 million gallons per day (MGD) capacity each combined with increasing the capacity of two existing trains to 3.0 MGD each for a total of 12 MGD.
Additional improvements include upgrades to the existing plant, equipment, and controls to provide flexibility of operation between and among the various treatment components.
The structural systems include concrete rectangular tank structures, maintenance and operations building, and elevated concrete tank structures. The operation building structural system is comprised of exterior masonry load bearing walls with tie column elements, interior structural steel columns, and a steel joist system to support the roof. Shallow concrete conventional wall foundations and column foundations were designed to support the structure.
The existing electrical distribution system was upgraded to 480V, 4-wire system. Additionally, three existing 500KW generators were replaced with larger stand-alone generators. New additions to the existing wastewater plant included clarifiers, 5-stage treatment process training, belt press, SCADA system, filters, and rehabilitation of RAS and WAS pumps.
