Wastewater Reuse Inventory* Last year, the Center for the Management, Utilization and Protection of Water Resources and the Tennessee Department of Environment and Conservation (TDEC) sent out the first of an annual survey of Tennessee wastewater treatment utilities (only those that are legally allowed to handle 0.1 million of gallons or more of water per day [mgd]) to find out which ones were using water conservation and water reuse practices. This is important to Tennessee as it faces strong pressures on its water resources from human use. You may also view these results from the Tennessee Department of Environment and Conservation's Web site links at http://www.state.tn.us/environment/dws/ and http://www.state.tn.us/environment/wpc/other.shtml. System Highlight: Sewanee Utility District (pdf file) We are spotlighting the Sewanee Utility District (SUD) this year as an example of a wastewater reuse facility. To learn more about how their system operates, contact Ben Beavers, general manager, at (931) 598-5611 or at 150 Sherwood Road, Sewanee, TN 37375. You may also read a brief description about the SUD by following the link above. (To view pdf files, you will need Adobe Acrobat software for Macintosh, Windows or Linux. This software is available free at www.adobe.com/products/acrobat/readstep.html.) 2006 Results Eighty-five household wastewater treatment facilities returned the survey. Of these, seven treated wastewater (or reclaimed water) to be reused in 2006. The total amount of wastewater these treatment facilities can handle is 20.92 mgd, and those facilities treated 15.6 mgd of domestic wastewater in 2006. Approximately 2.868 mgd of treated wastewater from these facilities were reused for beneficial purposes (like those listed in the table below). This table shows the number of facilities that reuse water in each TDEC Environmental Field Office District. It also shows how the treated wastewater was used within each district (how many golf courses, schools and parks were irrigated with it, etc.). TDEC Environ.

*The questions and format of the inventory survey were patterned after the Florida Department of Environmental Protection (FDEP) Annual Reuse Report. The Center and TDEC express gratitude to Dr. David York (Water Reuse Coordinator, Department of Environmental Protection, 3900 Commonwealth Boulevard M.S. 49, Tallahassee, Florida 32399) for granting permission to utilize material contained in the FDEP Annual Reuse Report. Appreciation is also extended to the Tennessee Association of Utility Districts (TAUD) for providing their support of the Reuse Inventory.
