Know Where to Find Your Septic System Tank

House With Septic System

Pumping your septic system every 3-5 years should prevent an expensive backup. However, not knowing where your septic system is in your yard will make it difficult to spot and repair leaks or flooding in a timely manner. The following potential solutions may help you find your septic system tank.

Locate the Main Sewer Line

Locate the main sewer line in your basement or crawl space. It is usually 4” in diameter and will be made from cast iron or PVC pipe. Note where this pipe exits your home then go outside to the corresponding spot. Normally, drain pipes are laid in straight lines. So, in theory, you should be able to find your septic system tank by tracing this straight line from the drain pipe to the septic system tank.

Indications of a large buried object may be a large divot or hill, or patchy parts of the lawn. If an untreated septic system has reached its limit, you may find it by smell. Typically, you will not see your septic system near a well water system, paved surface or major yard features like a pool.

Your septic system tank may have one or two lids. There will be two lids if it has dual compartments for filtering and breaking down waste. Lids are usually raised up from the main tank, making a soil probe an ideal tool to find them.

Use a Probe

Any probe-like object such as a four-foot piece of rebar will work. Do not push the probe too hard when searching your yard. You do not want to damage your septic system tank lid. You may need to tap the probe with a mallet to search for a septic tank that has been deeply buried. Septic tanks can be installed up to four feet deep. You will need to uncover the lid with a shovel.

Find Clues

Should this fail and your home is not too old to have public records, you can try checking with your city, town or county records for a septic system permit.

If the homes in your neighborhood are similar, a neighbor may know where their septic system is buried and from that, you might guess the location of your own septic system.

Mark The Spot

It is important to mark your septic tank location as soon as you find it. Do not rely on memory. A lawn ornament placed over the lid is ideal for marking the spot. Also, take measurements from the nearest two corners of your home and record them with your important papers for future reference.

Jim is a true professional who worked with me over months to identify and correct septic field problems. His positive attitude and helpful discussion in resolving issues is the best I found.


Mike and Shane came out and did an outstanding job on replacing our septic pump. Same day service - and they came out on a Friday evening! Mother's day would not have been very happy if they didn't save the day. HIGHLY RECOMMEND!!


We had our septic tank pumped and baffle tee replaced. The guys were on time, respectful and quick. They cleaned up very well after the job and even fluffed our pine straw to perfection!! We'd recommend these guys without hesitation.


Michael and Shane did an awesome job. Had to pump the septic,install a new baffle tee and tail out line. Very little yard displaced. Will definitely use Septic Service Pro again. Very pleased.


We live in Dawsonville. The crew that came out was very professional. The company owner explained to me the value and the many details about the septic that I did not know, that is why I chose them in the first place. Excellent service. R.McGary


Jim and his crew installed a new leech field for us quickly and professionally at a very reasonable cost. They handled all of the permitting and inspections and completed the work in a timely manner. Would recommend them to anyone.


Michael and assistant pointed out a leaking toilet that I didn't know I had (saved me $ there!). They also disturbed very little of the yard to get to the tank. Not the super cheapest but no hard upsell when they got here. Very pleased.


The team was efficient, friendly, knowledgeable and FAST to arrive. The bill was extremely reasonable for the work needed to be done. I would HIGHLY recommend Septic Service Pro.


These guys were amazing. Jim and Mike came when they said they would, did the job, explained everything they did. Very courteous,and professional. I am a handicapped person and felt extremely comfortable with them at my home. Thank you!!!!!
