Water Quality Reports
The State of Tennessee and EPA require us to test and report on our water on a regular basis. Results of unregulated contaminant analysis are available upon request. Please note that annual Water Quality Reports are posted in May of the following year.
Our 2019 Water Quality Report Is Available Now
The main takeaway for 2019: Not a single violation according to state and federal standards for water quality.
During June 2020, our residential and commercial customers will receive a printed version of the 2019 report in their billing statements. Customers who receive e-bills will find a notice on their statements to view the report on CUD’s website.
Among other items of note from the report …
- The primary surface water source for Rutherford County is located at the East Fork of the Stones River at J. Percy Priest Lake. Community water systems are required to note the detection of contaminants from their source areas. However, bottled water companies are not required to comply with this rule.
- The filtration process at the K. Thomas Hutchinson Water Treatment Plant removes contaminants from our water supply. Staff at the plant collect samples of raw water each day to measure conditions including temperature, turbidity (cloudiness), and the level of mineral content.
- The water is cleansed with a mix of chlorine, chlorine dioxide, carbon, and coagulant before flowing into filters containing anthracite and sand. The state requires chlorine at a minimum of 0.2 milligrams per liter in at least 95 percent of samples taken throughout the water system.
- Finished water runs through 11 testing parameters each day to ensure quality, and a minimum of 120 samples are collected and analyzed each month to check for bacteria.
