Like many water utilities, the City of Greenwood, Arkansas has small diameter water lines that are not capable of providing adequate fire flow. In an effort to improve fire flow capabilities and to provide a fire hydrant spacing of 500 feet or less, the City invested in a capital improvements project to replace approximately 2,800-linear feet of 2-inch galvanized water line with 8-inch and 6-inch water lines through an established neighborhood. Hawkins-Weir Engineers (HW) provided project design services, periodic construction observation, and construction management services for the project.
Creek crossings are notorious for water line leaks and failures. The City’s 8-inch water line crossing of Fourche Creek had been undercut and exposed by floodwaters, posing an imminent threat of failure. HW coordinated with the US Army Corps of Engineers to secure the necessary permitting and developed plans and specifications to replace the existing water line with an 8-inch water line installed 3 feet below the flow line of the creek and encased in a concrete slurry. Hawkins-Weir provided project design services, periodic construction observation, and construction management services for the project.
