        Reusing Wastewater

        This video demonstrates how peat filtration beds at Bernheim Arboretum and Research Forest near Louisville, Kentucky purify and conserve wastewater and eliminate one cause of non-point-source water pollution. In many rural areas, wastewater from houses and other buildings flows into septic tanks and then into septic fields, where it can contaminate groundwater. At Bernheim, wastewater from the Visitor Center flows into a septic tank, but from there, it is released into filtration beds where microorganisms break down contaminants. The water that emerges from these filtration beds is clean enough to use for irrigation in the Center's greenhouse.
