I'm not going to describe all the details of what happened here. Nor can I offer any explanation for how an intelligent, educated, adult could completely ignore the rules of physics that would dictate what would happen when a valve, at the end of a horizontal pipe that is holding back 120 lbs. of waste water, is opened.
Anyone who has ever dumped the full blackwater tank on an RV knows how hard it is to close the valve before allowing the entire tank to empty. I now know this too. After the first few seconds of frozen horror, I was able to react when I realized that the contents of the tank was going to forcefully overshoot the 5 gallon bucket sitting below the end of the pipe. I yanked the bucket up over the opening on the pipe while simultaneously slamming the valve shut. Sort of... I got the valve shut after working it back and forth a few times, luckily before the bucket filled.
Well, long story short, after getting a garbage bag for my clothes, changing clothes, and grabbing another change of clothes for after my shower, I headed for a visit with one of the few people I knew that had electricity and working water. After my shower, and finishing my load of laundry, I headed back home, where I added a little bleach to the few jugs of drinking water I had and tried to rinse the splatters off the driveway, which created a fine layer of ice on the cement.
I sure wish the electric would come back on.
