Around here, the ground is way too hard for that. They use a big "pressure washer" to break up the hard clay, then the slurry is sucked up.

Yup. Hydrovac. Very common in Canada too. I've never heard of "dry" hydrovac. Very interesting. "Pin It")

A few years ago I did something very similar on a much smaller scale using my shop vac
Shop vac shovel
Never try to tell me it can't be done
When I have to paint I use KBS products

Oh that's good. Duct tape a garden hose to the business end of that and you're on to something.
very common in industrial excavation around power cables, pipes etc. the Kingvac 6000 trucks are not cheap, so it's mostly industry that can afford to hire them.
The alternative is hand excavation since a trencher or backhoe bucket can cause lots of unwanted damage, guys with shovels and picks can do a lot of damage as well.

Digging a hole like that must really suck!
