Officials for the City of Bingen have known for awhile that their water system has been leaking large amounts. But when the city discovered that its pipes had leaked over half of all water that had passed through it in 2010, city officials knew they had to find the leaks, and fast.

"I was outraged at the number," said Mayor Betty Barnes. The number she refers to is the city's original calculation that it lost 53.65 percent of its piped water in 2010, known as distribution system leakage, or DSL. "It is unacceptable."
