Our company is the largest provider of steel water pipe manufacturing spirally welded pipe, rolled-and-welded straight seam pipes for the water market in diameters of 14-inch through 146-inch.
Potable Water Systems – A conveyance portion of a potable water system consists of Transmission mains, and a network of Distribution mains. Raw water, whether it is drawn from surface or ground supplies, must first be conveyed to a community, then distributed to consumers.
Conveyance from the source to the point of treatment is typically provided by larger diameter pipelines, called transmission mains, typically at least 14-inch in diameter. Following treatment, transmission mains also carry the potable water to the distribution pipeline network for delivery to homes and businesses.
Transmission lines contain few interconnections, while the distribution system is a complex network of loops and interconnecting pipes of small diameters, typically no larger than 12-inch. Today, steel water pipe manufactured to AWWA C200 is one of the most widely used pipe materials for water transmission.
For large diameter water transmission applications, steel pipe is most widely specified today
Some of the largest water transmission projects are being built with spiral welded steel pipelines. The Integrated Pipeline (IPL) project is 148 miles in length with pipe diameters of 108-inch, and is being built in North Texas to bring water from Lake Palestine to Tarrant Regional Water District and the Dallas Water Utilities. The Provo Reservoir Canal Enclosure Project was a 21-mile long, 126-inch diameter pipeline, with polyurethane lining and coating, built to enclose a canal and prevent an annual loss of 2.6 billion gallons of water. Stake holders included the US Bureau of Reclamation, Metropolitan Water District of Salt Lake & Sandy, Jordan Valley Water Conservancy District, and the Central Utah Water Conservancy District. Construction was recently completed on the 45-mile long, 66-inch diameter, Southern Delivery System in Colorado. The purpose of the project is to convey raw water from the Arkansas River stored in the Pueblo Reservoir to the City of Colorado Springs, the City of Fountain, Security Water District, and Pueblo West Metropolitan District.
