How to DOCUMENT the SEPTIC TANK LOCATION - How to Measure and Document the Septic Tank Location

When the septic tank needs to be pumped, a regular maintenance task, the cost of that service will be less if the property owner found the septic tank location and perhaps even uncovered the septic tank pumping access cover.

Other reasons to make a drawing of the the septic tank and drainfield location include enabling the inspecting and testing septic systems when buying a home or for safety, to assure that the septic tank cover is in good condition.

To remember the tank location in the future and to help future owners of the property, you should:

  • Mark the tank location with a flat stone or slate
  • Make a sketch Measure the exact location of the septic tank cleanout opening relative to the building: using "triangulation" you need to make only two measurements.
    1. From the tank cleanout, measure the distance to a permanent site feature such as the left corner of the building.
    2. Then measure the distance to a second permanent site feature such as the right corner of the building.
    3. These two distances can be set off in the future, even if the tank is hidden from view.
    4. Where the two points meet will be the tank cover.

Recording Septic Tank Location in our "Septic Tank Pumping Guide" includes a nice example of how to take measurements to document the exact location of a septic system component.

When you find your septic tank, if other clues helped you do so, please forward them to me by email so we can help others. Photos are very welcome too.
