F. Wayne Hill Water Resource Center & Plant Tour

Gwinnett County Department of Water Resources is committed to providing superior water service at an excellent value in one of the fastest growing regions in the United States. An important part of this service is to recover resources from wastewater: reclaim water to return to the water supply, convert gas to energy, and reclaim nutrients to create fertilizer.

The F. Wayne Hill Water Resources Center is one of the largest ozone and membrane wastewater treatment facilities in the world, with the ability to process up to 60 million gallons of wastewater per day. This reclaimed water is returned as high quality effluent to Lake Lanier, or through a 20‐mile pipeline to a discharge point at the Chattahoochee River. Gwinnett’s return of this valuable water resource to Lake Lanier recharges the supply for water withdrawal needs.

The gas‐to‐energy process a can produce up to 40 percent of the plant's energy needs, as well as all of the heat needed to operate its anaerobic digesters. Bacteria in the egg‐shaped digesters turn wastewater solids into methane gas at temperatures near 100 degrees Fahrenheit, reducing the waste that goes to landfills. The gas by‐product was previously burned off as waste. 

The nutrient reclamation process, known as the Ostara Pearl® process, recovers more than 85 percent of the phosphorus and 40 percent of the nitrogen from nutrient‐rich process streams before they accumulate as struvite on pipes and equipment. Two reactors turn the nutrients into slow‐release fertilizer, Crystal Green, which is sold into the agriculture, turf, and horticulture markets. The facility has the capacity to produce up to 1,400 tons per year.

The Center site is over 700 acres, with approximately 180 of those used for the water reclamation facility. The additional 500+ acres are used for buffer zones, wildlife habitat and preservation, walking and nature trails, and the Gwinnett Environmental and Heritage Center.

WaterHub® at Emory University
Wednesday, May 9
8:00 am – 12:00 pm 
Cost: $45 (includes transportation from the Hotel and back)

Join us as we tour the WaterHub® at Emory University.  The first system of its kind installed in the United States, the WaterHub is an on-site, district-scale water reclamation and reuse system serving Emory University’s main campus just outside of Atlanta, GA. The system mines up to 400,000 gallons of campus wastewater and utilizes eco-engineered processes to treat the wastewater for non-potable demands including heating, cooling and toilet flushing. The WaterHub enables the University to reduce its draw of potable water by up to 146 million gallons annually – displacing nearly 40% of total campus water demand. Moving the field of water reclamation forward, the WaterHub serves as a model for district-scale sustainable water management in urban areas.
