Drinking / Household Water

Drinking water supplies are either public or private. Public water systems are managed by municipal water utility companies or smaller public water systems may be operated by one owner or operator. Public water supplies in Tennessee are regulated by the TDEC Division of Water Resources Water Supply Program  and the EPA Drinking Water Program

Information about your public water system is available from your local water utility, the SDWIS EPA database or the TDEC Division of Water Resources regional office.

To find your local water utility, call the city or county where you live or you may use the Safe Drinking Water Information System to narrow your choices.

Private Water Supplies

Private water supplies include wells or springs serving 1 to 14 service connections and less than 25 people less than 60 days per year.  In Tennessee, there are no regulations regarding private drinking water quality.  Individuals using a private water supply are encouraged to test their drinking water annually for pathogens and at least every other year for chemical contaminants, especially if the nearby land use includes current or former industrial activities. Water treatment systems may be installed to improve drinking water quality in private water supplies. More information about private water supplies may be found on the  Tennessee Department of Health  and the Tennessee Department of Environment and Conservation’s Water Supply Program websites.

Camping and Emergency Drinking Water

When in situations where your normal source of household water is unavailable, such as while camping or during a water related emergency only use water from known sources and treat the water before consuming. As always, the best time to plan is before a disaster happens.
