The contractors will have to have the first and second phases of the project done by November and April of next year, respectively, said Lake Barkley Water District Manager Terry Goins.
The first phase involves upgrades and renovations to the Lake Barkley Water Treatment Plant, including an increase of the plant capacity from 2 million gallons to 4 million gallons per day, Goins said.
The contractors have 430 days from Sept. 14 to complete the first phase, which means they will have to have that phase complete by Nov. 8, 2011, said Goins.
The general manager stated that contractors will also refurbish the raw water intake and will install three new raw water pumps, each with 50 horsepower, and a new 600,000-gallon concrete clearwell, or underground storage tank, will be installed and will compliment the existing 250,000-gallon tank.
The current 8-inch and 12-inch water lines, which connect Lake Barkley to the plant, will be replaced with a 16-inch ductile iron raw water line, said Goins, who insisted that carrying capacity to the plant won’t suffer.
Other renovations include two new 32,000-gallon flocculation basins, which will help bring the clear clean water to the top, and a new rapid mix, which will the stir the water, said Goins.
Also included are a new 87,000-gallon sedimentation basin, a new chemical storage and feed facility, a new high service pump building with three new 250-horsepower pumps, a new water analysis laboratory and renovation of four water filters, Goins said.
The second phase involves the installation of a new 16-inch ductile water main from the water treatment plant to the bottom of Pete Light Hill on U.S. 68, and construction will begin at the discretion of the contractor, Goins said.
The contractors will have 240 days from Sept. 14 to complete this phase, which means they need to have it completed by April 18, 2011, said Goins.
To pay for both phases of the project, the district is taking out a $5,439,000 rural development loan from the U.S. Department of Agriculture (USDA), as well as a $1,354,700 USDA rural development grant, a $1 million Kentucky infrastructure grant and a $240,600 Environmental Protection Agency (EPA) grant, said Goins.
There were 15 firms that placed bids on the water line project with bids that ranged from Cumberland Pipes’s bid of $1,311,390 to a bid of $2,579,911 by Lakeshore Engineering of Cadiz. Twin State’s bid was for $1,311,941.
By contrast, there were just four bids on the water treatment plant expansion project, with bids ranging from the Smith Contractors bid of $5,685,750 to a bid for $6,215,825 by Hall Contracting of Louisville.
Of the bids for the plant expansion project that were collected by GRW Engineers, the firm responsible for the overall project, the board chose Smith Contractors of Lawrenceburg with little discussion at the first meeting last Monday afternoon.
