Overreacting to a little pee

They drained the reservoir, all 7.8 million gallons, because a man peed in it. 

About 1:30 AM on Wednesday, city of Portland water officials say, a 21-year-old man was caught on camera urinating in one of Portland's uncovered reservoirs -- one that provides water to a majority of Portlanders.

"Do you want to drink pee?" David Shaff, administrator of the Portland Water Bureau, asked.

And so now they are going to replace the 7.8 million gallons with a different 7.8 million gallons. 

Did anyone tell these people that fish and birds pee? 

And poop?
