Not an answer exactly, but the river flooded out the campground waste treatement plant at a local park. The park manager told me that after talking with the state experts, he was directed to requisition 2,000 gallons of ... human waste, for want of a more colorful and direct term, in order to "reprime" the system.
He did, and a week later it caught another freak flood and he had to buy another 2,000 gallons. So, the next time somebody tells you "I'm not in the sh*t business", tell them they're missing a profitable opportunity.
I swear it's true, not even I could make up a story like this.
