Advanced Integrated Pond System

The 0.2 MGD advanced integrated pond system can achieve 81% reduction in BOD and TSS. It also functions as a flow equalization basin in the event of repairs to either activated sludge system.

Wes-Tec South Oxidation Ditch

The 1.25 MGD Wes-Tec oxidation ditch was put into service in 2005 and can achieve 99% reduction in BOD, TSS, and nitrogen. This system saves on electrical costs by controlling oxygen levels using varispeed drive 100 HP aerators.
