Regaining a water resource for communities along the Lake Mead shoreline

This report discusses a project to upgrade four small water treatment plants on the shores of Lake Mead National Recreation Area. Construction involved replacing the old dual‐media gravity filtration systems with new plants using the latest in filtration technology. The project also addressed the efficiency of irrigation systems by replacing existing flood irrigation systems with a more efficient drip system and by reducing the use of membrane filtration reject into the irrigation system to reduce potable water use. A combination microfiltration/nanofiltration treatment processes was selected for the replacement treatment plants. The article discusses the creation of a desert water team by the contractor to manage all four projects as one program with project oversight being provided from one central office where all documentation and data control were conducted. The article also describes how trouble‐shooting in the desert required creative solutions, and the problems that were encountered when the treatment plants were due to start‐up.
