I installed quite a few pumped storage sewer systems for the owner of a old apartment complex, and a few rental houses that this guy owned.
This guy is a retired Navy man, which he joined after doing 4 years in the Marine Corp, and he is a Ditch Digging Son Of a Gun.
Forget the trencher, he wants to, and does all of the trenching by hand.
He even has a assortment of special shovels and hand tools that he's created to do the job.
One installation had a 4ft diameter x 6ft deep collection tank that had to be buried, and he dug the hole by himself.
The trenches that he dug were perfectly straight, the correct depth to the inch, and the bottoms were so clean that they looked like he swept them out with a broom.
I'm talking maybe 10 holes of various diameter from 3' to 6', depths of 4' to 6', and probably 200' of trenching.
This all was in rocky soil, so there were a lot of rocks laying around when he finished.
I've never met anyone like him, that guy loves to dig in the ground.
It's not about saving money either.
