AMERICAN Helps Quench Music City’s Thirst in 24/7 Water Main Project

This article also appeared on Water Online.

Crews in Nashville and Davidson County, Tennessee, at times have worked around the clock – 24 hours a day, seven days a week – to complete Metro Water Services’ Cumberland City Low Transmission Water Main project. There is good reason for this full-throttle approach. It minimizes traffic issues and allows for more scheduling flexibility.

This project is part of Metro Water Services’ master growth plan that will provide system redundancies needed to help eliminate potential water pressure and flow problems in the future. Metro Water Services currently maintains 3,000 miles of water lines and has a capacity of 180 million gallons per day pumped from two water treatment plants. This project will help Metro Water stay ahead of the area’s continued population growth.

Garney Construction, contractor for the $32.9 million project, selected AMERICAN to provide almost 12,000 feet of 60-inch and more than 13,000 feet of 36-inch ductile iron pipe. AMERICAN Flow Control is also providing 13 resilient wedge gate valves with Flex-Ring ends in sizes 24, 36 and 60 inches in diameter. Project work began in early February and is expected to be complete by the end of 2017.

“Our relationship with AMERICAN goes back many years. We buy all our ductile iron pipe from AMERICAN. It’s a partnership.” – Jeff Seal, Garney regional operations manager

“Our relationship with AMERICAN goes back many years,” said Jeff Seal, regional operations manager for Garney and primary point-of-contact for the project. “We buy all our ductile iron pipe from AMERICAN. It’s a partnership.”

To optimize the dependability of the Low Transmission Water Main project, Metro Water Services specified resilient wedge gate valves. “AMERICAN is the only company that makes the resilient wedge gate valve with Flex-Ring restrained joint ends in the larger sizes we needed,” said Seal. “AMERICAN’s Flex-Ring end gate valve provides additional flexibility and deflection as the ground moves and shifts.”

To select a route providing the best flow conditions, Metro Water’s project team – including engineering firm Gresham, Smith and Partners – evaluated and compared multiple alternatives. Consideration was given to criteria including environmental, legal, water quality, permitting, property acquisition, constructability, cost, schedule and overall impact to customers.

Before ground was broken, AMERICAN worked with Garney Construction to develop a precise lay schedule for various sections of the pipeline, making installation of the pipe much easier in the field. That kind of planning will pay big dividends later when Garney crews lay a portion of the pipeline across the bottom of the Stones River. The river depth varies from 5 to 40 feet, depending on how much water is released by the J. Percy Priest Dam.

Pictured is AMERICAN’s 60-inch Series 2500 RW gate valve, which weighs nearly 30,000 pounds and has a height of more than 13 feet. It is the first and the largest resilient wedge gate valve in the industry of its kind, without flanged ends.

AMERICAN Ductile Iron Pipe is providing almost 12,000 feet of 60-inch and more than 13,000 feet of 36-inch pipe for Metro Water Services’ Low Transmission Water Main project.
