How to get a copy of your septic record in Dawson County
1
Identify your property markers
Septic records are filed under the parcel identification number (APN) or original subdivision lot number rather than resident names. Obtain your parcel ID from your property tax statement or county deed.
2
Check the official repository
Dawson County files are accessible online via the official document portal: Open Official Viewer.
3
Request an as-built drawing and inspection card
Ensure you request the as-built construction diagram, which shows exact footages from house corners to the septic tank lid, distribution box, and lateral absorption trenches.
