It is perhaps not so easy to locate a septic tank hidden on your property, especially if it has not been properly documented or maintained. Septic tanks are underground, and their locations are not necessarily apparent. If you need to locate one for maintenance, inspection, or home remodeling, here are easy but effective tips on how to do it.
Look through Property Records and Maps
Your first move should be to review property records and building permits. Records for most homes provide the original septic system plan. Visit your local municipal or health department office to get a how to find septic tank of the septic plans for your home. These records will usually include a map showing where the tank was installed.
Look for Sewer Pipes in the Basement or Crawlspace
Find the master sewer pipe in your home. It is a large pipe (usually 4 inches in diameter) that sends wastewater from your home to the septic tank. It will typically leave through the foundation wall and go in the direction of the septic system. Follow the path of this pipe outside your home to get an idea of where the tank would be buried.
Look for Yard Signs
Septic tanks also create subtle yard signs. Look for:
Depressions or Bumps – A septic tank or drain field can create a visible depression or bump in the ground.
Green Grass – If one area of grass is growing faster and looking greener than the rest of the grass, it could be due to septic tank moisture.
Unusual Odors – A faint smell of sewage in some areas can suggest that you are close to the septic system.
Use a Metal Probe or Soil Probe
The position of solid material in the ground can be found by using a 4-foot metal rod. Drive the rod into the earth, probing for a huge, flat area, which is sure to be the top of the septic tank. Be careful of cutting pipes and even the tank.
Mark the Vent Pipes and Clean-Outs
Search for small vertical pipes protruding from the ground on your land. These are possibly vent pipes or clean-out pipes from the septic. These should usually determine the approximate area of the tank and drain field.
Utilize a Septic Tank Locator Tool
If all of the above methods do not succeed, you can employ the use of a septic tank locator. The device works by flushing a transmitter down the toilet. The transmitter sends signals to a receiver, which leads you to the exact location where the tank is.
Call in a Professional
As a second option, a septic professional can locate the how to find septic tank in a matter of seconds with devices such as ground-penetrating radar or electronic probes. Yes, it is worth paying someone, but you’ll save time and you won’t damage the system by mistake.
Look Around Average Places of Installation
Septic tanks are usually installed:
10-25 feet from the house.
In a location that will not interfere with service truck access for maintenance.
Away from driveways, large trees, and wells.
Look for Inspection Covers and Lids
Septic tank lids or access covers may be just a few inches below the surface. Carefully dig around suspected areas and inspect for concrete or plastic lids. Avoid puncturing the lid or disturbing the system.
Ask Former Owners or Neighbors
If you are a new homeowner, it is useful to consult the previous owner or neighbors. They might know where the tank is or have some useful information gathered during previous maintenance operations.

If it is required, use a probe, locator device, or call in a professional. Now that you have found the tank, mark the area for reference later. Regular maintenance and check-ups will keep your septic system running efficiently and save you the cost of having to do costly repairs.
