CSO Community Notification

​

Indiana Law (327 IAC 5-2.1) requires communities with combined sewer overflows (CSOs) to educate the public about potential health impacts from contact with combined sewer overflow discharges, alert members of the public who are affected by CSOs and enable the public to better protect themselves from exposure to waterborne pathogens associated with CSOs.  The City of Sullivan has two CSOs that discharge into Buck Creek, on the East side off US 41, between Washington St. and Silver St. and one CSO that discharges into Busseron Creek for a total of three CSOs.  Combined Sewer Overflows (CSOs) occur when the capacity of the sewer system and treatment plant are exceeded due to rainfall or snowmelt.  When this occurs, an excess mixture of storm water and wastewater may be discharged into Buck Creek and Busseron Creeks through these three CSOs.  The greatest impact of discharges from CSOs is associated with bacteria in the untreated sewage and storm water run-off.  Bacteria levels in Buck and Busseron Creeks can rise for several days following a CSO discharge.  Notification signs have been posted at all CSO locations.  For more information, contact Tony Burkhart at 812-564-1161.
