Some middle Tennesseans are digging wells in an attempt to save on water bills. Well diggers stay busy in Middle Tennessee, but, as drought conditions near, homeowners are seeking out their skills even more. Well digger Freddie Lancaster told Nashville's News 2, "People get to panicking, get scared." He continued, "We put a lot more wells in town when it goes to getting dry."He explained, "Everybody wants a green grass, a green yard." The second generation well digger said Middle Tennessee's hot and dry weather has meant an outpouring of business on his end. While digging a well is not cheap, the long term benefits are seen in years when rain is scarce and water bills go up in an attempt to keep the lawn green. Lancaster said 90 percent of the time they find water. So the next time you pass a green lawn after sweating it through days of 100 plus degree weather, either a lot of money is being spent, or a well has been dug."You'll see a lot of signs in the yard that say, 'irrigating by well,'" explained Lancaster.Depending on depth, a well can cost between $3000 and $10,000.
