WI DNR Code/Guidelines Well and Pressure Systems

Well Casing Height WI DNR Code:  During a well inspection or drilling of a new well the WI DNR has a code requirement to be met with regards to the height of your well casing.  If you are planning on having a new well drilled keep in mind the well casing height needs to extend a minimum of 12 inches above outside grade (above ground).  If you are planning on landscaping (see General Info on landscaping) around your well, keep the 12 inch height requirement in mind to avoid non-compliance with DNR regulations.

The following is a list of DNR Well Casing height requirements for existing wells.  Note these are all minimum height requirements.

  • Wells constructed prior to April 10, 1953 shall terminate a minimum of 6 inches above established ground grade.
  • Wells constructed between 1953 and February 1, 1991 shall terminate a minimum of 8 inches above established ground grade.
  • Wells constructed after February 1, 1991 shall terminate at least 12 inches above established ground grade.
  • Wells located in a floodplain constructed on or after October 1, 1975 shall extend a minimum of 2 feet above the regional flood elevation for the well site.
