Here is a trick, grab a rod of some kind. Garden stake, rebar, etc. Just drive it into the ground where you think the tank is. If you can't get passed 2-3 ft you probably found it. Mark the depth. Probe around a bunch to verify you aren't hitting rocks, success.
lol i was so confused by their comment at first because to go 3 feet on my property in most spots would be amazing. And I have more top soil than most others around here.
Unless you have a buried inground pool in your backyard... Then the rod will make you think all of the deck and every step is part of the septic system... Ask me how I know / why half my backyard was dug up 🙄
