Press Enter to show all options, press Tab go to next option

The City’s sewer treatment plant is a Class III activated sludge plant with a nominal design flow capacity of 5.5 million gallons per day and peak hour flows approaching 10.5 million gallons per day.  As part of ongoing improvements to the City’s Sanitary Sewer System, additional work at the treatment plant will soon commence. 

In upcoming months, the City will be constructing a new, fixed-cover anaerobic digester in the existing Wastewater Treatment Plant (WWTP) located at 201 N. Worthen Street.  The new digester is planned to be sited on the north side of the WWTP adjacent to the existing solids handling building on an area previously used as municipal landfill. Construction is anticipated to begin in 2020 and proceed through 2021. The project will increase both sewer treatment capacity and system redundancy.
