Imagine it is a typical Tuesday morning and your alarm sounds. You slap at the buttons to turn off the blaring buzz, climb out of bed and shuffle to your bathroom to wash your face and brush your teeth. You are getting ready to start your day as an operator at the nearby drinking water treatment plant. You go turn on your tap, but nothing comes out. You try the shower and, again, nothing. The same goes for the kitchen faucet, the one next to your coffee pot. No shower, no pearly whites, no coffee?this is not going to be a good day.
