$4,803.00The Jessamine Creek Wastewater Treatment Plant is a 3.0 MGD average/10.4 MGD peak flow plant (expandable to 4.5 MGD average/14 MGD peak) and consists of a remote influent pump station; a screen building with fine screening and grit removal; a multichannel oxidation ditch with horizontal type mechanical aerators and automatic storm flow operation, two (2) 100¹ diameter circular clarifiers with density current baffles and algae sweeps, RAW/WAS pump station, tertiary filtration structure with 400 SF continuous backwash sand filter; disinfection structure with three (3) channels, two (2) equipped with ultraviolet disinfection equipment; effluent parshall flume and metering structure; aerobic sludge digester with diffused aeration; solids processing building with sludge dewatering performed using a 1.7 meter belt filter press with cake discharged by conveyor to a PFRP sludge stabilization system producing a Class A and B Sludge; odor control consisting of a three-tower wet scrubber system and a masonry operations building. Plant control included a supervisory control system and remote radio telemetry for the offsite influent pump station.
Improvements to the existing remote WWTP included in the project consisted of conversion of anaerobic sludge digestion to aerobic, conversion of gaseous chlorination/dechlorination to UV disinfection, and construction of a new sludge truck loading station.
W. Rogers Company (WRC) self-performed 75% of the work on the project. WRC drilled, shot, excavated and disposed of approximately 7,000 CY of rock; excavated, placed, redistributed or otherwise disposed of approximately 125,000 CY of earth; installed and tested 8,000' of exterior ductile iron pipe with fittings in sizes 3" to 36"; installed and tested 2,300' of 24" HDPE forcemain from the remote influent pump station to the plant site. WRC also installed and tested more than 4,000' of small diameter PVC water and chemical feed piping, and placed and cured more than 7,600 CY of structural concrete. This required the construction, placement and removal of more than 164,000 SF of forming surface and finishing of approximately the same quantity.
