You can see alligators and ancient cypress trees in Corkscrew Swamp, a National Audubon Society nature sanctuary. But an equally fascinating sight is the sewage treatment plant. You can stroll through on your way to the restroom. Wastewater filters through a series of tanks filled with bacteria and water plants . . . Then the water flows through two artificial marshes, where swamp plants remove the last traces of nitrogen.
Clean water is returned to the restrooms for further flushing.
It's a cost-effective process, and it's totally natural. The EnvironMinute is produced in cooperation with the National Safety Council and made possible by the Teresa and H. John Heinz III Foundation.
