Officials in Johnson City anticipate work on the city’s water tank to be complete just before the end of summer.  

There are major changes atop Tannery Knob in downtown Johnson City- and not all of them involve bike trails.  Replacement of the Tannery Knob water tank is an impressive undertaking that will expand storage there by 2 million gallons.

“The original, 3 million gallon tank was a cast-in-place concrete reservoir that was built in the 1930s and had reached the end of its useful service life,” said Water and Sewer Services Director Tom Witherspoon.  “The new 5 million gallon prestressed concrete tank will be placed into service in early August…”

“Water storage tanks are an important part of our infrastructure because they allow us to meet daily and seasonal demands as well as to be prepared for emergency events like fires and widespread power outages,” Witherspoon said.
