Where is my septic tank? Answered from the public record.

  1. 01

    Enter the property address

    We geocode the address and search county and state septic records within the parcel.

  2. 02

    We match government records

    Permit files, health-department GIS layers and state septic inventories — never guesses dressed up as data.

  3. 03

    Get the location and the report

    GPS coordinates, distance from the house, permit details when on file, and a PDF you can hand to a client or crew.

We label what we know — and what we don't.

Septic records vary wildly by county. Instead of presenting every point as exact, each field in a TankFindr report carries one of three labels, so you know when to trust it and when to probe first.

How we source our data
  • Verified

    Taken directly from a permit or official record — permit number, system type, install date, GPS point.

  • Inferred

    Calculated from verified fields, such as tank size from permitted capacity or age from permit date.

  • Estimated

    From statewide inventories that locate systems at the parcel level. Good for "septic or sewer?" — confirm before digging.
