When rain doesn't come it is called a drought. Water conservation is needed before and during a drought.
As of 2007 Orme, Tennessee was one of the hardest-hit communities in the drought-ridden southeastern United States, due to its dependence on two vulnerable water sources: a waterfall-fed creek and a natural spring that delivered up to 60,000 gallons/day (227,000 liters/day). These sources dried up to only 5,000 gallons/day (19,000 liters/day), not enough to pressurize the supply lines to the town's residents.
A temporary solution was arranged inwhich a 1961 firetruck hauls water to the town from Alabama providing enough water to keep the system running for only three hours each day, from 18:00 to 21:00 local time.
The mayor of Orme, Tony Reames, arranged a permanent solution in the form of a connection to the municipal system of the nearby community of Bridgeport, Alabama. In his words: "It's not a short-term solution. It is THE solution." The connection would be via a 2.5 mile (4 km) pipe between the two communities, paid for by an emergency grant of $377,590 from the USDA. The project was hoped to be completed by the end of November 2007.
