apparatus - ✔✔Position/park the MWS apparatus so that it's ready to begin dumping its
load into a portable tank.
Start the clock on the dump valve is opened.
Keep the clock running as the MWS apparatus leaves the dumpsite, drives to the fill
site, and then returns to the dumpsite.
Stop the clock when the MWS apparatus dump valve is back in the proper position to
dump its next load.
