An "Odor Control" project also commenced on February 4, 2009 and will serve to scrub the foul air which may be emitted on occasion from specific process units. This project is slated for completion later in 2010.
3.1 Twelve Mile Creek Water Reclamation Facility
Permit No. NC0085359. Twelve Mile is an extended aeration facility utilizing biological nutrient removal and tertiary filtration. Disinfection is accomplished via UV (ultraviolet light). Twelve Mile effluent is discharged into Twelve Mile Creek, which is part of the Catawba River Basin. The facility is permitted to discharge up to 6.0 MGD of treated wastewater. January 18, 2008, the Twelve Mile facility was permitted to dispense bulk "reclaimed" water to authorized users (Permit No. WQ0032519). Bulk reclaimed water has multiple "Non-potable" uses which can serve to reduce demand upon the potable water supply and distribution system. The bulk reclaimed water program was suspended in the fall of 2008 pending a system upgrade which includes secondary disinfection. Operational changes have been successfully implemented to control phosphorous quantities discharged. A "Plant Reliability Enhancements" project which commenced February 4, 2009 will serve to aid monitoring and control operations upon completion in early 2010. An "Odor Control" project also commenced on February 4, 2009 and will serve to scrub the foul air which may be emitted on occasion from specific process units. This project is slated for completion later in 2010. Twelve Mile Creek WWTP is located at 8299 Kensington Drive and serves Waxhaw as well as portions of Indian Trail, Stallings and Weddington.
