The Wastewater Division is responsible for the operation, maintenance and repair of the wastewater treatement facility at 14901 Poplar Avenue. The treatment plant covers approximately 240 acres and has a design capacity of 2.75 million gallons per day.
The City's Water Quality control Facility (WQCF) is located at 14901 Poplar Avenue. The Wastewater Treatment Division is mananged by the City's Wastewater Superintendent. The WQCF is rated to treat 2.75 million gallons of wastewater treatment daily.
Daily operation of the plant is under the guidance of the Chief Plant Operator. There are currently two other operator positions authorized.

This 1.0 MGD Lakeside Oxidation Ditch was built in 1980 and typically achieves 99% + reduction in biochemical oxygen demand (BOD) and total suspended solids. It will be studied for suitability for upgrades such as nutrient deduction and energy efficiency.

The 0.5 MGD advanced integrated pond system can achieve 81% reductionin BOD and TSS. It also functions as a flow equalization basin in the event of repairs to either activated sludge system.

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.
Digester and Biosolids 
The 2005 plant addition also included a three cell aerobic digester and six drying beds for volitile solids reduction and biosolids dewatering for disposal.
Clarifier Effluent Weir

Wastewater consists of used water, human waste, and toilet paper. The activated sludge process at Patterson consistently removes 99% of these pollutants to produce quality water for groundwater disposal.
