Make sure you have easily removable grates for your drains so these can be hosed down daily. Cuts down on fruit flies. A Drain outside your cold room so the condensate drain can be put there. You don't want to have anything in your drain in the cooler that would be a pain moving pallets etc. Drains going into a collection area to catch the solids? Have a floor mop sink in the brewery too.
Edit, Don't forget a 2,3 or 4 compartment sinks near the production areas. Need a place to clean the smaller parts.
