Sherrill Wastewater Treatment Plant & Collection System Improvements

What was the challenge?

The City of Sherrill Wastewater Treatment Plant (WWTP) and Collection System Improvements Project upgraded all treatment processes at the WWTP, which had been in continuous operation for 40 years and were operating past their useful lives.

How did Barton & Loguidice provide a solution?

The project included improvements to all process treatment systems including new vortex grit removal, influent mechanical fine screen, oxidation ditch rotors, final clarifier mechanicals, aerobic digestion, sludge transfer pumps, and collection system rehabilitation. New UV disinfection was also installed as required by the New York State Department of Environmental Conservation (NYSDEC) State Pollutant Discharge Elimination (SPDES) permit,

Why was the project a success?

This project utilized innovative and improved process equipment, where feasible, to improve treatment capabilities, efficiency, and safety. A mechanical fine screen and washer compactor replaced a channel grinder. The fine screen removes wipes and plastics that had become prevalent in the last few years and clog downstream pumps. The washer compactor removes water from the screenings and returns organic material to the liquid flow for secondary treatment.
