I moved into my house a year ago and was told that I had a septic tank. My water bill confirms it, but I can't seem to find it. There are no clean outs or covered concrete pipes. It is not on my plat either. How can I find it? Any suggestions would be great. Thanks in advance!

Best way: Call a septic cleanout service person.. your neighbors may have recommendations since they are likely on septic too, if you are.

If you don't know where your tank is, and you didn't have it opened and inspected when you bought the house, you should get someone over there to inspect it right away. It may not seem like that big a deal when the septic fills up and makes the ground squishy, but what's really happening is grease and poo is clogging up the soil in your drainfield. I promise that the fix for that will be painful... expensive and intrusive.

In my neck of the woods (southern MD) it's only abouy $200 to have the guy come and pump the tank. He will find it on his own. It's well worth the money.

Well at least here, going back 20 years, all septic systems have to be approved and inspected. The county has a special inspector just for that.
In his office they have lay outs for all the septic systems,

But basically the septic tank companies and clean out people, find where your sewer line comes out of the house, and they use a metal rod, and keep pushing it into the ground intill they hit it.

There is a four inch pipe up the side of your home, the vent pipe.
At the bottom of this pipe is the sewage pipe to your septic tank, dig along the pipe, follow it until you find the septic tank. Easy as pie, it won't be very deep below the surface and it should run in a straight line.
