The WaterHub

The WaterHub® is an eco-engineered water reclamation and reuse system that combines natural treatment techniques with the latest filtration and disinfection technologies. With increased microbial biodiversity, WaterHub (hydroponic) treatment systems provide a more resilient biological process design, with reduced energy profiles, a compact physical footprint and reduced biosolid production. WaterHub® systems are customized to each site and application from industrial pretreatment to district-scale, on-demand recycled water facilities. With a lush, natural system aesthetics, full odor-control and automated operational features, the WaterHub is designed for integration into urban settings.


Sustainable Water offers turn-key project financing through a Water Processing Agreement (WPA). Similar to a Power Purchase Agreement, a WPA is a financing vehicle that allows Sustainable Water to fully design, build, own and operate the WaterHub® at no capital expense or development risk to the end user.

Sustainable Water designed the WaterHub at Emory University to integrate into the existing campus framework using two small parcels near Chappell Park Field. Up to 400,000 gallons of wastewater is mined directly out of the campus sewer system daily. Water is cleaned to Georgia Reclaimed Water Standards through an energy efficient, eco-engineered treatment process supported by solar (PV) energy production. The system has 50,000 gallons of clean water storage capacity, providing N+1 redundancy for campus district energy systems. Recycled water is distributed to multiple utility plants and select dormitories for toilet flushing via a 4,400 linear foot “purple pipe” distribution system.

The WaterHub reduces Emory’s draw of potable water by up to 146 million gallons annually. Since its commissioning in May 2015, the WaterHub has processed over 150 million gallons of water. In addition to its function as a water reclamation system, the WaterHub is designed to promote research and community outreach, enhancing the concept of the campus as a living, learning laboratory. With built-in lab space and easy access ports for water quality testing, the facility enables research in a variety of topics. The lower site also includes a demonstration reciprocating wetland system (ReCip®) as a showcase to visitors interested in other sustainable treatment technologies.
