I feel like sometimes I post the craziest topics.
For the microbrewery I'm building, it's going to be in a shed in a corner of the yard - regs say it has to be a separate building - and that's pretty far from the basement where I'll be doing the conditioning. It would certainly be easier if, instead of putting fermenters on dollys and wheeling them down to the basement, I could just run a big tube underground and into the basement. What potential issues would I face here? Obviously I'd flush the piping after every brew.
Another potential would be to forego a wort chiller and have the pipe running from the brewery to basement BE the chiller. I'm thinking about this in one of two ways:
First, dig deep enough that I get cold(er) earth, and the wort cools by virtue of heat disippation into the surrounding earth by direct contact of pipe to ground
Second, make a giant counterflow chiller, running water from the basement into the shed via the larger diameter pipe, and running the wort into the basement in the opposite direction. Collected water from chilling could be used for garden water, cleaning, etc.
The final follow-up to this would be, according to code, what distance would I need between a water line and an electrical line, running parallel underground? Elec will be GFI.
