Smith Seckman Reid, Inc., (SSR), a Nashville-based engineering, design and facility consulting firm, was recently awarded the 2010 Engineering Excellence Award by the American Council of Engineering Companies (ACEC) of Tennessee for its work on the Stones River Water Treatment Plant located in Murfreesboro, Tenn.

Leading the competition’s Water and Wastewater category, SSR project highlights from the $40 million facility upgrade, include:

• Installation of a new membrane filtration system—now able to process 20 million gallons of water per day, Stones River is the largest membrane filtration system in Tennessee
• Replacement of facility chemical storage and dosing system
• A full transition of the facility’s disinfection system from the hazardous chemical gaseous chlorine to the much safer alternative onsite sodium hypochlorite generation
• Installation of a granular activated carbon (GAC) filtration system, helping to reduce pharmaceutical and total organic compounds in the finished water supply
• Commissioning of standby power generation for the facility

Built in 1966, the Stones River Water Treatment Plant had not previously undergone a facility expansion since 1981.
