Franklin, Tennessee Water Outage Today

Who runs the water in Franklin: system profile

The system behind most taps in Franklin is Franklin Water Dept, which EPA records list as serving roughly 77,222 people. Customers know it as City of Franklin Water Management; the name on your bill is the one to call.

What feeds the taps in Franklin

Tap water in Franklin starts as surface water. Franklin Water Dept takes it from the Reservoir and the Harpeth River and runs it through treatment before it reaches the mains. Treatment points named in EPA's facility list include Harpeth River Plant. After treatment the water is held in 9 storage tanks and reservoirs, which is the buffer that keeps taps running for a few hours after a pump or main fails.

The outage angle. Surface water needs a treatment plant running around the clock, so a plant shutdown, a raw-water pump failure or a long power cut at the plant can lower pressure across the whole service area, not just on one street. Boil water notices are more likely to be citywide after that kind of failure than after a single main break.

Main breaks and shutoffs in Franklin: the usual causes

These are the causes that match the record for Franklin, listed roughly in order of how much they matter here.

• Freezing weather. Franklin sees about 68 days a year with a low at or below 32°F, and 11 days at or below 20°F. The coldest morning in the 2015 through 2025 record came on February 19, 2015. The longest stretch with highs that never rose above freezing ran 6 days, ending February 20, 2015. Frozen service lines and meters cause single-address outages, while ground frost and thaw cycles crack older mains and produce the street-wide breaks.
• Flooding and heavy rain. NOAA logged 55 flood, flash flood and heavy rain reports in Williamson County from 2015 through 2026, and 10 days a year bring an inch of rain or more. Flooding is hard on water systems in three ways: it erodes soil around pipe crossings, drowns pumps and electrical equipment, and can let contaminated runoff into the mains, which triggers precautionary boil notices.
• Storm-driven power loss. Thunderstorm wind, hail and tornado reports in Williamson County number 329 since 2015. Pump stations and treatment plants that depend on Middle Tennessee Electric (MTE) run on the electric grid, so a storm that downs power lines can lower water pressure even when no pipe is damaged.
• Younger pipe, different risks. Only 7% of occupied homes in Franklin predate 1970 (US 35.5%), so more of the network is newer plastic or ductile iron. Breaks tend to come from construction damage, pressure surges and weather rather than age.
• Digging and utility work. Street projects, fiber installation and excavation near buried pipe regularly cut mains in Franklin with no warning, usually on a day with perfectly ordinary weather.
• One-address problems. A closed valve, a meter swap or a failed regulator can leave a single house dry. Compare notes with a neighbor first; if they have water too, start with your own plumbing.

Franklin weather and water-main stress, 2015–2025

Main break season in Franklin runs from late fall into early spring, with the coldest stretch around December through February.

A note on the numbers: they are modeled for the city center and averaged over eleven years, so they show how often Franklin sees each kind of weather, not what any one thermometer read on a given day.

Franklin boil water notices and EPA compliance record

EPA lists 7 health-based violations for Franklin Water Dept since 2015, which is more than most systems of its size. It also lists 9 monitoring or reporting entries that are about paperwork rather than water quality, such as a missed sample or a late report.

Most recent health-based entries:

• January 2023: Drinking water above the legal limit for total trihalomethanes It is marked resolved.
• October 2022: Drinking water above the legal limit for total trihalomethanes It is marked resolved.
• July 2022: Drinking water above the legal limit for total trihalomethanes It is marked resolved.

A boil water notice in Franklin is a separate thing from a violation. City of Franklin Water Management issues one when pressure falls low enough for contamination to enter the pipes, after a main break is repaired, or when a routine test comes back positive. The Tennessee Department of Environment and Conservation (TDEC) oversees the process, and the notice stays until clean samples come back, usually a day or two after pressure returns.

Lead service lines and old plumbing in Franklin

The most recent 90th-percentile lead result filed for Franklin Water Dept is 1 ppb (2025). The federal action level is 15 ppb, so that result is well under it.

The age of the housing matters more than the utility's test average: 7% of occupied homes in Franklin predate 1970 and 1986 was the year lead pipe and solder were banned. Flush the cold tap after an outage and ask City of Franklin Water Management whether your service line is on its lead inventory.

Restoration times for water outages in Franklin

Most repairs of an ordinary main break in Franklin take half a day once the crew is on site. Bigger mains, deep bury and busy roads stretch that to a day or more.

City of Franklin Water Management will post an estimated restoration time for a break that affects many customers; ask for the repair crew's estimate when you call.

How much water to keep on hand in Franklin

With about 2.6 people in the typical Franklin home, FEMA's one-gallon-per-person-per-day rule means 8 gallons covers three days and 36 gallons covers two weeks.

• A standard water heater is a ready-made 40-gallon reserve. Shut off its power or gas, open a hot tap somewhere in the house, and draw from the drain valve.
• Fill a tub or large containers early for toilets, cleaning and handwashing, and store drinking water separately in clean bottles.
