Wastewater/Sewer Management

Wastewater / Sewer Management

The primary duty of the Wastewater Division is conveyance and treatment of wastewater flow from homes, businesses, and industries.  This Division also manages the storm water system, ditches, and culverts.  The Wastewater Division is guided by the Ohio Environmental Protection Agency (OEPA) through the National Pollution Discharge Elimination System (NPDES) permit number 0PE00000.

 

Sewer Maintenance

The wastewater collection system began installation in 1955, and continues to grow.  It contains piping in sizes from 6 to 60 inches in diameter that collects flows from homes, businesses, industries, storm water runoff, and Muskingum County.  The Sewer Maintenance crews are charged with routine cleaning, inspection, and repair of this vast system.  They are also responsible for the installation and maintenance of over 300 individual home grinder pump stations located in the City’s East End.

The City of Zanesville has a Combined Sewer Overflow (CSO) system.  This type of system combines normal sewer wastewater with storm water that is collected from streets.  In order to reduce sewer backups during high (storm period) flows, relief points were placed in the system that discharge directly to a waterway.  Under direction of the 1974 Clean Water Act, these types of systems must be removed or modified to allow zero discharge of untreated sewage to the waterways.  In order to achieve this, the City has created a Long Term Control Plan (LTCP) with the OEPA.  Work to achieve this goal has been ongoing for several years, and will continue until the main objective is satisfied.

If you are interested in connecting to the sewer collection system, please contact the City’s Engineering Department at City Hall at (740) 455-0601, extension 105.

It is important to note that the City is responsible for the sewer main pipe, while homeowners are responsible for any problems with the pipe extended to the home (sewer lateral pipe).  The Sewer Maintenance staff is available 24 hours daily for sewer backup related issues.  If a problem occurs, please call the Wastewater Plant for assistance.  It is recommended you call this Division prior to calling a plumber.

 

Wastewater Treatment

The Wastewater Treatment Plant was originally built in 1959, and has undergone several improvements through 2009.  The current plant processes are screenings, grit removal, primary clarification, trickling filters, aerated biological treatment, chlorine disinfection, anaerobic digestion, and a dewatering process.  This Advanced Secondary Treatment facility is rated for 11 Million Gallons per Day (MGD) of treatment, but can treat a peak flow of about 32 MGD before discharging into the Muskingum River.  Average daily flow is about 6 MGD.  The plant is operated both manually and automatically through a Supervisory Control and Data Acquisition (SCADA) system.

The Wastewater Plant treats for specific types of waste, and must therefore control what is discharged to the collection system.  These control mechanisms are found in the City’s Codified Ordinances, Chapters 922 and 923.  A Pretreatment Program is operated to monitor discharges from businesses (mainly grease control) and industries.  For questions about discharges to the sewer collection system, contact the Pretreatment Coordinator at the Wastewater Plant.

The Wastewater Plant personnel are charged with the proper operation and maintenance of the equipment, and monitoring the processes and streams from them in order to meet the limits of the NPDES permit.

 

The Wastewater Division offers plant tours and classroom training.  If you would like to schedule a tour, training, or if you have any questions, please contact the Wastewater Plant office during normal business hours.
