Consolidating 2 Into 1
Gresham Smith was selected as part of a design-build team with Garney Construction to provide improvements to the aging pretreatment infrastructure. The award-winning project consolidated two influent components—the headworks and grit removal process—into a single headworks facility equipped with a new odor control system and a septage receiving station.
The upgrades included flow metering and sampling, four fine-screening channels with band screens and washer/compactors, and three stacked-tray grit removal systems with associated grit pumping and classifiers. The facility is capable of treating an average of 66 million gallons per day (MGD) with bypass capabilities of up to 120 MGD.
Maintaining Operations & Outreach
The design-build team successfully maintained plant operations throughout the project thanks to the carefully executed bypass sequencing and maintenance plan. The project also included effective community outreach to minimize disruption to residents, particularly given the facility’s location between two neighborhoods. The leading-edge project ensures that the South Cross Bayou AWRF continues to deliver reliable and sustainable service to Pinellas County residents and businesses.
