I have a small 500 gal septic tank that is fed from only a seldom used basement guest bath, but now needing to be pumped. Last time it was pumped was 25 years ago and, since then, a sidewalk has been poured over about 1/2 of the tank (oops!). Is there a way to install a riser to the other 1/2 of the tank to allow pumping without having to destroy the sidewalk? I dug down to the lid and it's about 20" below the surface. How to go about cuting a hole in the lid for the riser without taking off or destroying the lid?
