What is required for septic system maintenance?

Maintenance and inspection is required for ALL septic systems in Winnebago County. The Zoning Office will send requests for pumping information three (3) years from the last maintenance date on file. It is the property owner’s responsibility to read the letter completely and comply with the requirements stated therein. Holding tanks are pumped and inspected when full. Pumping / inspection reports are then filed in the zoning office by the licensed pumper.
