The Southern Nevada Water Authority (SNWA) has tapped Broomfield, Colo.-based MWH to design a new water supply intake in Lake Mead that will provide drought protection and water-quality improvements for more than 1 million residents of southern Nevada. The design phase of the project is expected to be completed within two years, and construction will be completed by 2011. The total project cost is estimated at $650 million.

Lake Mead Intake No. 3 will replace the 600 mgd capacity of the older, existing intake in the instance that Lake Mead's water surface drops below an elevation of 1050 feet above sea level. The intake also will allow access to better water quality at deeper levels of the lake.
