Thanks for all the suggestions, guys. I think we'll end up doing a long trench in between the rows of fermentors, and then just grade the floor under the brewhouse so that runoff drains to the trench. We'll also probably do another trench in the packaging area. We're going to put a circle drain in the cold room, one in the bar, and one in each bathroom.
Floor drain in Packaging area is a great idea.
My chiller is indoors and I do get a lot of condensations from pump that is in the chiller.
So think about that walking cooler and chiller create condensations and you have to do something with it.
