CSO Public Notification

Combined Sewer Overflow Notification Program

The City of Marion has started a Combined Sewer Overflow (CSO) Notification Program designed to educate and notify the public about the city's combined sewer system. The program uses a CSO information line, general information website and signs posted on waterways at various locations throughout the city to provide information to interested citizens.

Program Objectives

  • Notify interested residents when CSO discharges are influencing the water quality of the Mississinewa River in the Marion area
  • Educate the public about the potential hazards and impacts of CSO discharges, and
  • Enable citizens to take appropriate steps to protect themselves and their families from exposure to waters affected by city CSO discharges.

How to Participate

Telephone Information Line - Contact the City of Marion Engineering Department
Information Line Number

CSO Information Website - The CSO Website includes background information about the city's combined sewer system, locations of CSO discharge points, and what efforts the city is currently taking to improve the water quality of the Mississinewa River. The information posted on the website will be periodically updated.

The city is currently in the process of updating existing CSO signs and posting additional signs at several locations. The new signs notify the public of the CSO Information Line, and discuss the potential hazards of water affected by CSO discharges. The city is placing the updated signs near CSO discharge points, parks and other public access points.

For additional information about the CSO Notification Program please contact Pat Pinkerton of the Marion Utilities at 765-664-2391.
