LaVergne Water Plant at a Glance
The facility currently produces an average of four million gallons of high quality drinking water per day utilizing coagulation, flocculation, sedimentation, and multimedia filtration processes.

The plant has a state certified, in-house bacteriological laboratory that undergoes regular state and federal inspections for quality assurance and quality control. The finished water is disinfected using Sodium Hypochlorite. Fluoride is added for dental health.

Collecting Samples
Severn Trent Services collects water quality samples from various points throughout the treatment facility several times a day, 24 hours per day, and 365 days per year. As specified by state and federal regulations, technicians collect and analyze 40 samples per month from homes throughout the city.

To ensure that the samples represent the entire water distribution system, the system is divided into 30 zones. One sample is collected from each zone every month for laboratory analyses to guarantee that the water is of the highest level of quality and safety.

Protecting Citizens
Always putting the health of La Vergne citizens first, the water distribution network is designed with a cross-connection system that protects customers from contamination through back-siphoning from various commercial taps.

As required by regulations of the Federal Safe Drinking Water Act, technicians inspect and certify performance of approximately 1,200 backflow prevention devices throughout the distribution system annually.

Awards and Recognition
In 2009, 2011, 2012, 2013, and 2014 the U.S. Department of Health and Human Services and the Centers for Disease Control and Prevention recognized the operations of Severn Trent Services in La Vergne for the professional regulation of fluoride content at the optimum level.

Consistent, first-rate water fluoridation practice, as demonstrated by our water system, is a safe and effective method in preventing tooth decay, improving the oral health of community residents of all ages. In addition, the treatment facility has earned the distinction of being a State Approved Water System by the Tennessee Department of Environment and Conservation, Water Supply Division.
