Wastewater Treatment Plant

aThe wastewater treatment plant has seven (7) departments with 43 employees (Administration (3), Pretreatment (3), Laboratory (3), Plant Operations (7), Plant Maintenance (4) and Sewer Maintenance (23).

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 for four (4) hours and 30 million gallons per day continuously for the duration of the rain event. Beginning in 2010, during a significant rain event, the treatment plant will process up to 40 million gallons per day for four (4) hours and then 30 million gallons per day continuously and will process an additional 40 million gallons per day of combined wastewater / storm water.

The treatment plant operates and maintains eighteen (18) 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 a jet rodder is about 3,500 feet cleaned per day and from a mechanical rodder is about 2,000 feet cleaned per day.  Sewer maintenance crews are assigned to planned preventive maintenance four days per week (Monday through Thursday).  The crew’s work in specific sections are assigned by their supervisors.  All sanitary, combined and storm sewers (including catch basins) are cleaned in a section. The goal is for all sewers less than twenty-four (24’’) inch to be cleaned annually.

Structural problems within the sewer system are identified by a variety of methods including but not limited to TV Inspections, as a result of a citizen complaint or emergency stoppage, reports from cleaning crews or reports from inspection/survey crews.  In 2011, a "Job Order" program was established. This program consist of various department creating work orders and assigning them to the various departments within the Utility. 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.
