The City’s existing wastewater plant has been in service since September 1992. The plant provides adequate treatment to meet discharge limits, but is now loaded above its organic capacity at 131% of design. Bonds were secured to fund Phase 2 of a plant expansion as well as selecting a Contractor to complete the construction of the expansion. Construction will begin in Feb 2017. Phase 2 will increase the plant’s organic loading capacity as well as provide several system improvements. The total projected cost is $8.5M. Phase 2 of the expansion will reuse the vast majority of the existing plant. All the tankage will be reused and all equipment, with the exception of the current disinfection and dewatering equipment, will be reused. Chlorination-dechlorination equipment will be replaced with ultraviolet light disinfection to reduce potential hazards to the receiving stream. Sludge solids will continue to be composted for reuse as a soil amendment.
After the main treatment processes, wastewater solids are dewatered, mixed with wood chips and composted. The City’s compost meets all standards for EPA’s “unrestricted use” category. This compost makes a great soil amendment and is free to City residents. Call 687-6016.
