At a previous place of employment, we took a 55-gallon drum, had it fitted with a standard water spigot on the side near the bottom, and built a cart with wheels for it.  The cart was high enough that a garden-type hose, attached to the spigot could be placed in a low sink so that the water could easily be drained. The cart was low enough to avoid a high center of gravity, so it would not tip over easily.  The wheels should be able to be locked.  It was easy to roll the semi-filled drum to an appropriate sink, or, if one was close by, just place the end of the hose into it.  We kept the hose short (under 10 feet) to keep it from being snaked across a room.

Last May ANSI introduced standards that require an annual full 15 
minute flush and calculation of the flow rate of eye washes and 
showers.  As the person that checks all 64 eyewashes/ showers on 
campus let me say that floor drains would've been a godsend.   My 
showers will fill a 30 gallon bucket anywhere from 30 seconds to 1 
minute.   I tried using a sump pump to direct the water into a sink, 
but those drains are overwhelmed in 3 minutes.   Where I have windows 
that will open, I run the hose out the building.   For those that I 
don't have windows I haven't come up with a good solution yet.   Ideas 
anyone?   Physical plant has told me just to run hose from the lab on 
the 3rd floor all the way through the building and out the front 
door.    I understand the reasoning behind prohibiting floor drains - 
but can't they come up with drains that will remain closed until 
someone opens them?
