Wastewater Treatment Plant & Poplar Tree Reuse System

The wastewater treatment plant operations includes activities and tasks that have the potential of affecting the public’s health or the environment. Operator’s actions could change the treatment plant’s effluent or bio-solids quality. Operational activities confirm process modes, change process modes, handle treatment plant products, and maintain product quality. The activities directly determine effluent and biosolids quality that could affect public health. The activities use the majority of the direct and indirect materials consumed at the POTW. Most POTW energy and chemical use is consumed in process control activities at the treatment plant and lift stations. POTW operators operate the treatment plant, poplar reuse system, lift stations, and force mains.
