Septic tank under driveway

[Jordan L.]

Hi all, I own a SFR in which I've learned the septic tank is located partially under the driveway. I bought the property last year without knowing its history, so I attempted to have the tank pumped only to learn the septic company would either have to tear out the driveway over the tank, or charge me $50/foot to dig and hopefully find the clean-out (though it's not guaranteed they'd find it). It's an older driveway so the tank had to have been pumped at some point. Is there an alternative solution that I'm missing? The tank was installed when the property was built in 1957.
