Will be building where there is only 6ft below floor elevation to bed rock. will be on a septic system so getting a 10ft to bottom type tank will be very difficult. If I set the tank on top of the bedrock it will take an ejector pump to get into a normal tank.
Is it a real PTA to use an ejector on the sewage line. I have delt with ejectors on the septic effluent with no trouble but not the inlet.
No aerobic tanks!!!!!!!!!!

Blasting?
I would only base a whole-house sewer on an ejector pump if there were absolutely no other way. I'd rather hammer out the rock and make a hole for the tank. Can you get to the drain field by gravity if you do that? If you have to go with the pump then I'd also install a generator, unless you think your electric service is absolutely reliable.
Not going to try to blast into this rock. Setting on top of rock will permit gravity to field. Already committed to stand-by generator.
I had a similar situation when I built my house. My septic system designer specified a "low boy" septic tank. It's still a thousand gallon tank only its about 4.5 feet deep. No problems after 7 years. This may help you shoot for a gravity system, or at least minimize your ledge removal.
Gravity never fails.
Moving parts will eventualy fail.
Like Frede said there are "lowboy" tanks.
Here's one from the plastic guys.

Maybe I'm wrong but isn't Bed rock is a pretty large catagory.
Could a backhoe dig it out?
Is there layers to it?
With the right contractor/equiptment it might come right out.

Aside from the problem David pointed out (no drains if you lose electrical power), I don't see any problem with using a trash pump to hoist the crud up into the septic tank. If you've already committed to a standby genny, you oughta be good.
We do this all the time with below-grade bathrooms and laundry rooms, so there's no reason it shouldn't work for draining the entire house although the size of the holding tank might have to be increased. A lot of them are plastic, about the size of a big garbage can, but I'm sure you can get bigger ones if necessary. Set the holding tank/pumping station below the floor of the basement with a grinder/trash pump in it, and away you go.
Oh, yeah, put a high-level alarm in that holding tank to warn you if the pump craaps out, the float-switch jams, or the circuit-breaker kicks out for some reason.
