FRANKLIN, Tenn. -- The drought in Tennessee has put the city of Franklin down to just a day's supply of water.

A pool of sludge is all that's left of the Harpeth River, a major water source for Franklin.

"We recently went nine consecutive days where we drew no water from the Harpeth River," said city administrator Jay Johnson.

The city is buying most of its water from the Harpeth Valley utility district. Electric motors pump water into the city's system.

"If we had a major power failure, if we had a major water line break, anything that disrupts normal operation during peak demand like this, can escalate into a crisis,” said Johnson.

But due to similar situations around the state, there are limits on how much water the city can buy.

The holding reservoir at the Franklin Water Department looks more like a beach right now instead of a lake.

There is an even bigger concern in the next few months because September and October are usually the driest months for the state.

"If our river is essentially dry in mid-August, that means we've got 60 to 75 more days of this,” said Johnson.

If Mother Nature doesn't provide some significant rain soon, some businesses may have to make big changes.

"We may ask a car wash that has 10 bays to close three or four of them. We might ask a laundry mat to adjust their hours,” said Johnson.

All non-essential water use is restricted. Residents can water their plants, but irrigating yards is out of the question. On Tuesday, the city cut service to 199 automatic sprinkler systems.

City officials said those who over water their yard will be given a warning. The second time the resident is caught, the city could turn off their water.
