9-Year Recipient of Director's Award

The Safe Drinking Water Act (SDWA) is the federal law that imposes regulations on the quality of drinking water water suppliers must adhere to.  The United States Environmental Protection Agency (USEPA) is responsible for administering the SDWA.  Tennessee American Water ensures the drinking water our customers receive is as good as or better than EPA standards. We are regulated by the US EPA and the Tennessee Department of Environment and Conservation (TDEC). 

Tennessee American Water has been an active participant in the Partnership for Safe Water program. The Partnership's mission is to "improve the quality of drinking water deliver to customers of public water supplies by optimizing system operations." Tennessee American Water's Citico treatment facility has received the Director's Award for the last nine years in recognition of adherence to the high operating standards of the Partnership.

From the moment water is collected from the Tennessee River at Tennessee American Water's treatment plant on Citico Drive the process of creating quality water for its customers begins.  In the treatment facility, water goes through six basic treatment steps:

1. Disinfection - Chlorine is added to kill bacteria or other microorganisms in the water. 

2. Coagulation - Special compounds are added to the water to help accumulate the silt and other particles from the water.

3. Sedimentation - The particles accumulated during coagulation become heavy and settle to the bottom of the sedimentation vessel.

4. Filtration - Following sedimentation, the clarified water passes through filters containing fine sand and granular activated carbon to remove very small particles and unpleasant taste and odor causing compounds.

5. Final Chemical Treatment - Following filtration, and before water is distributed to customers, the water is treated with approved chemicals in accordance with state and federal regulations. Chlorine is added as a disinfectant for the water during distribution; fluoride is added for dental health; and corrosion control chemicals are added to help prevent corrosion of home plumbing. 

6. Storage - Water is placed in a closed tank or reservoir to be used in meeting constantly changing water needs of the community.

Throughout the water treatment process Tennessee American Water experts test the water hundreds of times daily to ensure treatment is effective.
