How We Serve You:
The City of Kokomo’s wastewater treatment plant is monitored 24 hours per day and is designed to treat 23.5 million gallons per day of all dry weather sewage transported by the collection system. Since the sewer system is combined (sewage and storm water), during a rain event, the treatment plant can process up to 40 million gallons per day continuously for the duration of the rain event. Beginning in 2010, after the construction of a Wet Weather Treatment Process, the treatment plant can process up to 40 million gallons per day continuously and will process an additional 40 million gallons per day of combined wastewater / storm water through the Wet Weather Treatment Process.

 The treatment plant operates and maintains twenty-two (22) lift stations. Each lift station is equipped with an alarm system which transmits an alarm by satellite to plant personnel.

 The City has approximately 300 miles of sewer lines within the service area.  Expected production from the City's Jet Rodder and Jet Vactor is approximately 3,500 feet cleaned. The Rodder (2) and Vactor (2) crews are assigned to specific grids within the City limits. All sanitary, combined and storm sewers (including catch basins) are cleaned per grid. The goal is to have all sewers, less than twenty-four (24’’) inch in diameter, to be cleaned annually.

 Structural problems within the sewer system are identified by a variety of methods, including but not limited to TV Inspections, citizen complaints or emergency stoppage, reports from cleaning crews or reports from inspection/survey crews.  Problems are categorized as major or minor.  Minor problems are generally those that require repairs requiring one day or less and do not require replacement of significant portions of the sewer system.  Examples of minor repairs are rehabilitation of existing catch basins or manholes or raising manholes.  Anything beyond the scope described above would be classified as a major problem

General Information:
The City of Kokomo's Wastewater Treatment Plant is regulated by the Indiana Department of Environmental Management through a National Pollutant Discharge Elimination System discharge permit (IN0032875). The City of Kokomo operates a Class IV, 23.5 MGD activated sludge treatment facility consisting of fine screening, grit removal, single stage nitrification, aeration tanks, secondary clarification, biological phosphorus removal, tertiary sand filtration, effluent chlorination/de-chlorination, aerated sludge holding tanks and a Class B Biosolids process utilizing a Centrifuge.

 The collection system is comprised of combined sanitary and storm sewers with twelve (11) Combined Sewer Overflow (CSO) locations, one (1) Wet Weather Treatment Facility (WWTF) outfall 027, and two (2) internal treatment plant bypass points.

The Kokomo Wastewater Treatment Plant is operating, maintaining and managing its combined sewer system and combined sewer overflows (CSOs) to comply with federal and state requirements, and more importantly, to preserve and protect the local and regional environment.  Kokomo is committed to properly managing CSOs and to abating, through proper control and management, adverse effects of overflows from the collection system to the local environment.
