If this occurs during normal business hours, please call the Wastewater Treatment Plant at 317-852-1114, or call the Utility Billing Office at 317-852-1102. You will need to actually speak to a person to ensure that your sewage issue will be addressed. Leaving a message will not address the issue. If this occurs outside of normal business hours, please call 911 and they will dispatch the appropriate personnel. Be prepared to provide your name, address and phone number.
