Construction continues on a $20 million water tank off old Frankfort Pike at the Town Branch sewage treatment plant.
On Thursday, crews were spraying concrete on the exterior of the 22 million-gallon storage tank. Construction began last fall and should be completed by December 2016.
The storage tank will prevent sewer lines from becoming overburdened during significant rain. The construction cost is $19.1 million. Design costs are more than $953,771.
The tank is part of a $590 million project required under a legal agreement the city signed after the U.S. Environmental Protection Agency sued Lexington for alleged violations of the federal Clean Water Act.
A second tank of similar size will be constructed on the site between 2020 and 2025.
