    Water flow in coffee roasting operation

    I am looking for a reference point here. I know that typically water is not used in the roasting process (unless you are quenching) but when setting up a wholesale roasting operation producing 500-1000 pounds of roasted coffee per week how much water are you using on a daily basis. I am referring to water used for washing hands & mopping up. The water that would be used for cupping and other "coffee lab" activities would not be involved at this location. My need for this info is based on doing a build out on a space that would require a new gray water drainage system where no septic/drainage system currently exists. By knowing the typical water flow/usage for a basic coffee roasting operation, I will be able to design the proper gray water drainage system.

    Any info any of y'all have on this would be great.
    Thanks!

    When I cup... I typically go through about 3 gallons of water for roughly 8 coffees (I use non-plumbed hot water dispensers)... maybe 12-15 gallons to wash dishes in 3 compartment sink, several gallons of coffee is brewed when dialing in new batch brew coffee, 3-5 gallons of water for mop, I have no idea how to gauge hand washing/toilets since I'm mainly plumbed into a sewer system.

    Thanks, That's what I figured, probably ~10 gallons per day.
