South Treatment Plant

The People

scientistThanks to nearly 140 dedicated employees, the South Plant treatment system runs 24 hours a day, seven days a week. Trained professionals – operators, lab technicians, maintenance crew members, process control personnel and administrative staff – ensure the South Plant and the pipelines and pump stations that supply it with wastewater operate effectively.

Operators, licensed by the state, are responsible for the daily operations; lab staff perform analysis of the plant processes and products; process control staff analyze the data to optimize the plant's operation; and crews of machinist, mechanics, and electrical and instrumentation staff maintain and repair equipment at the plant and at the conveyance facilities in the service area.

Our goal is to provide the region with the best wastewater treatment service available while operating as efficiently and effectively as possible.
