The Wastewater Treatment Facilities (WWTF) are located on outer Mitchell Avenue. The plant is operated by a Foreman (Tom Hose) and four Operator/Maintenance employees.The Robinson WWTP was newly constructed in 2010-2011 and includes a 2.5 MGD Advanced Activated Sludge Plant and complete laboratory where they perform process control and NPDES testing. They also maintain 12 sewage pumping stations located throughout the city and surrounding area, an Industrial Pretreatment Program and provide wastewater billing. The plant has consistently met or exceeded its NPDES permit requirements over the past 22 years. The Robinson Wastewater Treatment Facility finished a 7.8 million dollar upgrade in 2011. It is a state of the art activated sludge facility incorporated into their existing infrastructure.

Highlights of the new facility include Biological Nutrient Removal (Denitrification and Phosphorus removal), automated storm flow management, waste activated sludge screening and disposal, waste sludge conditioning to reduce waste sludge yield, ultraviolet disinfection, plant effluent water reuse and a comprehensive SCADA package which includes the plant and all 12 collection system lift stations.

The upgrade raised the plant design average flow capacity from 1.5 Million Gallons per Day (MGD) to 2.5 MGD and the design peak flow capacity from 3.75 MGD to 6.25 MGD. The expansion began on 5/6/10 and was completed on 9/5/2011.

They have a written safety program which includes monthly safety seminars. The seminars are presented in house by WWTF employees. The topics range from “Confined Space Entry”, to “Lockout – Tagout”. The facility promotes energy savings as well as pollution prevention & waste minimization by hosting Household Hazardous Waste, Electronics Takeback and Used Tire Collections. They provide tours for local schools, community colleges, civic organizations, and other interested groups and individuals.
