I use a 55-gallon drum, too, but have installed a small pond pump with a h ose that can be run to where needed.  This way the drum doesn’t n eed to be moved with the attendant spill OR injury issues.  It is moved with an ordinary hand truck.  This process is done monthly here and we can smell the clorine in the water, so imho the system is well flushed.

A t a previous place of employment, we took a 55-gallon drum, had it fitted wi th a standard water spigot on the side near the bottom, and built a cart wit h wheels for it.  The cart was high enough that a garden-type hose, att ached to the spigot could be placed in a low sink so that the water could ea sily 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 locke d.  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 int o a sink,  
but those drains are  overwhelmed in 3 minutes.   Where I ha ve windows  
that will  open, I run the hose out the building.   For thos e 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?
