Auburn Southside Wastewater Treatment Plant
Auburn, Alabama

The City of Auburn needed to upgrade the Southside Wastewater Treatment Plant and hired Goodwyn, Mills and Cawood, Inc. to provide the necessary design services. The existing facility was an activated sludge plant with an average daily flow capacity of 5.4 MGD and a peak flow of 16.4 MGD. GM&C designed an upgrade to the facility to increase its average daily flow to 9.0 MGD and a peak of 27.0 MGD. This upgrade included the installation of a new headworks with mechanical screens and grit removal, two anoxic pretreatment cells, additional aeration capacity for the existing diffused aeration system, the modification of parallel flow trains into a series type flow system, one new rim flow clarifier, a raw sewage lift station upgrade, clarifier flow control system, and a complete sludge handling facility with belt filter press, polymer feed, lime stabilization and aging cribs.
