For Barkley Lake water, several million gallons are considered to be “unaccounted for” every month, though this represents a fairly small percentage of their total volume every month.
“It’s not low enough to brag about,” said Lake Barkley Superintendent Terry Goins. Barkley Water reported a low water loss of 2,233,000 gallons lost in April 2007, or seven percent of its volume for the month. The highest loss came in the month of November, with 12,716,000 gallons, or 28 percent of is volume.
“We had a line break across the Little River. We don’t know how big of a leak it was or how long it had been leaking,” said Goins. “That line is shut down but we won’t know how bad it was until we know about the next month’s loss.”
Goins attributes much of the losses to broken and leaking lines. He said that the district works to repair known breakages, though is limited to what it can do given available manpower and funding to hire contractors.
“Some of our lines are made from asbestos fiber, which is almost like cardboard,” said Goins. “This is some of the original pipe in Trigg County, dating from the ‘60s to early 1970’s. We don’t use it any more, though it was popular at the time. As it is used, it grows more porous, absorbing water that seeps out. We have 150 miles of this stuff out of 450 miles of total pipe.”
Goins added that the district uses some cast iron pipe while the remainder is made of PVC.
