I have a 1250 gallon poly tank, both it's access man-holes are rubber gasketed.
I installed a 2 inch pump-out pipe through the top and going down to near the bottom, with a threaded coupling and cap.
And rather than putting it in the ground, I put ours in our basement. Now I know that it will not freeze, and I can easily pump it out without having to dig. Just thread on a fire pump suction hose and in a bit it can be empty.
No freezing, no digging it up to allow pumping, and no worries about folks driving over it.
A poly tank is also much cheaper than a concrete tank.
As for burying rubber, I live rural. We dont pay high enough taxes to support no inspectors. To have such bureaocrats on salary to give folks grief requires a much higher tax base, no thank you.
