How many uses are available before the typical portable restroom holding tank fills up and needs to be serviced?
Typically, portable restrooms contain a 50-60 gallon holding tank, and will fill up after approximately 75 uses. If you are using our “Port-A-Jon Rental Planning Chart” (see above link) to estimate the number of restrooms needed for your guests or patrons, the portable toilets will likely fill to capacity after about 6 hours of steady use.
