Water, water everywhere at Emory University

System saves millions of gallons

The landmark WaterHub at Emory University in Atlanta is an eco-friendly water recycling plant that cleanses 400,000 gallons per day of wastewater for purposes other than drinking.

Harnessing biomimicry processes, WaterHub uses beneficial bacteria, microorganisms, plants and hydroponic technology to treat black water, gray water and stormwater for later use in steam and chiller plants, as well as for toilet flushing in a number of residence halls.

The system, which also includes a 50,000-gallon reserve tank to support the university’s heating and cooling systems in case of emergency, reduces by 146 million gallons the annual amount that Emory drains off the Atlanta municipal water system.
