If you own a property with a septic system, understanding its location and depth is crucial for maintenance and potential repairs.  For people who have inherited or recently purchased a property, it may not be obvious where the septic tank is located. At Upfront Septic, we often get asked, “How deep are septic tanks buried?” and “How can I find my septic tank?” Here’s a comprehensive guide to help you navigate these questions.

How Deep Is A Septic System Buried

The depth at which septic tanks are buried can vary significantly based on several factors:

1. Soil Type and Ground Conditions: In regions with sandy or loose soil, septic tanks might be buried deeper to ensure stability. Conversely, in rocky or clay-rich areas, they might be placed closer to the surface.
2. Water Table Level: Areas with high water tables might require shallower septic tank installations to prevent contamination and ensure efficient drainage.
3. Local Regulations: Western Washington has specific regulations regarding the installation depth of septic systems to ensure environmental safety and system efficiency. Typically, septic tanks in this region are buried between 1 to 3 feet below the surface.
4. System Design: The design and size of your septic system can also influence how deep the tank is buried. Larger systems might need to be installed deeper to accommodate the tank’s dimensions and the accompanying drain field.
5. Distance From The Home.  In Washington, tanks need to be at least 5 feet away from the building; in some scenarios, it may be further.  The further the tank is from the house, the deeper it will need to be buried to ensure a downward slope in the drain pipes.

How To Locate Your Septic Tank

Not sure where your septic tank is? Here are some of the best ways to locate your septic tank:

1. Check Property Records: Often, the location of your septic tank is documented in your property records. Look for a map or diagram that indicates where the system was installed.  For some counties, this may be public information.
2. Look for Clues in the Yard: There might be subtle signs indicating the septic tank’s location, such as patches of greener grass or areas that seem slightly sunken. These can be hints that the tank is buried below.
3. Look For The Lids: Some (but not all) septic tanks will have above-ground cleanout lids that allow for easy access. These lids may be hidden under planters, bird baths, and other garden disguises.
4. Use a Soil Probe: A soil probe is a long, slender rod that can be inserted into the ground to detect buried objects. Carefully probe the soil around suspected areas until you hit the tank.
5. Consult Professionals: If you’re unable to find the septic tank on your own, professional septic service providers, like Upfront Septic, have specialized equipment and expertise to locate your system accurately.

It’s important to know where your home’s septic tank is buried for several reasons.  Mainly, it makes maintenance much faster.  If service providers cannot find your tank, they may have to dig up parts of your yard to find out where it is.  In an emergency septic scenario, getting to the tank quickly can be the difference between minor and major sewage back up in your home drains.  Knowing where the tank is located will also prevent any accidental construction or gardening mishaps.  If your tank doesn’t have one, consider getting risers installed.  A septic riser extends the septic lid up to the surface for easy access and location; if you don’t like the look of an above-ground lid, you can cleverly cover it with a stone, garden statue, or planter.
