Science Cafe: Sewer-ology

When we wash the dishes or flush a toilet, we send everything "down the drains," but where is "down the drain?" and what happens to the "used" water when it gets there? And can it ever be used again? Turning wastewater into a usable, nontoxic product is a science that's a little chemistry, a little biological engineering and a lot of yuck. Join us for Sewer-ology 101.
