Where's my septic tank?

If the previous homeowner did not provide this important information, you have several options.

  • If your home was built in the past twenty years or less, the local DHEC office should have a copy of your permit on file. In fact, any person or organization with a legitimate interest in or concern about a septic tank — whether they own the property in question or not — can request a copy of a septic tank permit from DHEC under the state's Freedom of Information Act (FOI).
  • To request a copy of your permit, print, fill out and fax DHEC an FOI form, which is required even if you own the property. If possible, add these details about the property to the FOI form:
    • Tax map number
    • Lot number
    • Block number
    • Physical address
    • Date system was installed (if known)
    • Name of original permit holder (if known)
    • Subdivision name (if located in a subdivision)
  • If your home was built before 1990, look around your yard for manhole covers or lids hidden by grass or leaves.
  • You can also call a licensed septic tank inspector or pumper to help you locate your system. Your local DHEC Environmental Health office can provide you with a list of licensed septic tank professionals in your area.
