Good Luck with your research!!How amount of water use per wash in a commercial washing machine?
Well, to give you an idea of relative sizes, those water coolers in an office with the big blue jugs of water on them contain about 5 gallons full. So a top load washer wouldn't even use all that. Maybe 4 gallons. My front load uses about 3.3 gallons of water.





But that's for just the wash. There is also the rinse to get out all the soap, so that's another 3.3 gallons, for under 7 gallons total per wash.





I'm not sure about commercial washers, if they use only 1 rinse cycle or 2. But let's say they use 2, so there's a total of 10 gallons of water per wash.





Putting it in perspective again, consider that your toilet uses 1.6 gallons of water per flush, so if you flush it 6 times a day, there's 10 gallons again.
i would say my washing machine about 20 gallons per load.
