You may already know that you have a septic system. If you're unsure, here are some signs that you probably do:

• You use well water.

• The waterline coming into your home does not have a meter.

• You show a "$0.00 Sewer Amount Charge" on your water or property tax bill.

• Your neighbors have a septic system.

Once you have determined that you have a septic system, you can find it by:

• Looking into your home's "as built" drawings.

• Checking your yard for lids or manhole covers.

• Contacting a septic system service provider to help you locate it.
