I'm making a small winery in my garage, and will need to wash dirty dishes/fill and clean the wine tanks regularly. There is currently a cold water spigot in the garage. I was hoping to rig a wash basin up to this so I can use the water supply with an industrial stainless sink.
My main concern is draining the waste water. I would be mostly draining dead yeast, old wine, soap and water and a mild bleach solution used for cleaning tanks.
I might have to drill through the cinder block foundation, into the basement and run drain pipe to either the clothes wash basin, or over twenty feet away to the main waste stack.
What are my options and what, if any laws are there regarding waste water? Can I use PEX or flexible tubing for the drain tube, and just let the waste dump into the sinks down in the basement?
I want to make as few alterations to the garage as possible, in case we ever have to sell the house. It would be good if I can yank the system and leave as little a mess as possible for future owners.
