Inside Marshalltown city limits, homes and businesses are served by the city’s Water Pollution Control plant on Woodland Street, which runs under its own Iowa DNR wastewater permit. Septic work around Marshalltown is mostly for the acreages, farmsteads and rural lots outside the city limits, where each property treats its own wastewater.
If you are buying or selling one of those properties, Iowa’s Time of Transfer law requires the septic system to be inspected by a DNR-certified inspector before the sale or deed transfer. Septic permits, repair and abandonment permits and Time of Transfer paperwork for the county all go through Marshall County Environmental Health, in the courthouse on East Main Street.
