Best way to remove 3’ of bed rock to burry septic tank?

[Professor Marvel]

where is this going to percolate or drain to?

Sounds like a jack-hammer job to me, just make believe your riding a Harley...............

I would get a quote and possibly hire it done. You would want to clear the rock deeper than just the minimum to lay a bed of sand in order to set the tank level. Rather than setting the tank on jagged rock creating voids and high pressure points on the tank bottom.

A small excavator with a hydraulic hammer would make short work of it.

I’m still recovering from a broke ankle. I can operate my backhoe but the man behind the jackhammer won’t be me. One of my buddies has a jackhammer. I might try to get him to try it before renting a mini excavator.

Get it blasted. They can do small charges and not disturb the house. You still have to dig it out with an excavator.

I’ve got a full size backhoe to do the digging but I don’t have a rock hammer or the hydraulics to run one so I’d have to rent the whole machine. I’ll check into the blasting option but I don’t have high hopes in finding someone to do it.

Only 30' from other houses, blasting bedrock? I don't think you are going to like the cost even if you can find a licensed contractor to do the blasting.

Hope you have good neighbors. Even small charges will be felt from the vibration of the blast. Then someone could be looking for a freebee to repair their long ago cracked drywall, ceiling plaster or whatever.

I don’t either. I figure somewhere on the $500 range to rent a mini with a rock hammer. I hope the mini is up for the job. I watched a 320 cat hammer all day to put in a culvert at gas station they’re building.

Drill it then use an expanding compound to crack it.

Then the hoe might work.

Sandstone does break well in layers,
