Central Missouri / Missouri River Corridor
Rural property here often means a private well and septic
Outside Hermann and Owensville, much of the county is rural, where homes rely on private wells and onsite septic systems that come with their own state rules and maintenance responsibilities.
Outside Hermann and Owensville, much of Gasconade County is rural. Out there, many homes do not use city water or city sewer. Instead, they use a private well for water. A well is a deep hole that pulls water from underground. They also use an onsite septic system. That is a tank in the yard that handles the home’s wastewater. If you are buying a rural home, this changes what you check. Test the well water for quality. Make sure the well gives enough water. Check that the septic system works and is permitted. The Missouri Department of Natural Resources sets septic rules and gives well guidance. The Department of Health and Senior Services has well-testing information. The smart move is to test the well and check the septic system before you close. Confirm any county permitting role with the county health office.
