For nearly 20 years drought conditions in the Colorado River Basin have caused Lake Mead to drop nearly 130 ft. In Southern Nevada, conservation efforts have reduced per capita use by 36 percent even as the population increased by more than 650,000 during the same period. Now work is in the final stages to develop a low lake level pumping station at Lake Mead to further ensure adequate water will be available in the most populous area of Nevada. Approved by the Southern Nevada Water Authority (SNWA) Board of Directors in May 2015, the $650 million project was awarded to Barnard of Nevada in September 2015, with completion expected in 2020. “When finished, this will enable us to access water under very low lake levels,” said Erika Moonin, project manager of SNWA. “The pump station is designed to operate at low lake level, from 875 feet above sea level to 1,060 above sea level. If lake comes up we can
switch back to other pump stations. But under very extreme low lake levels we will still have access to the community’s water supply.” The main components of the new pumping station include 34 well shafts more than 500 ft. deep
and 6 ft. in diameter to accommodate the pumps; a 26-ft. diameter access shaft; and an underground forebay 36 ft. high by 33 ft. wide by 377 ft. long. The flow rate of the pumping station will be more than 900 million gal. per day.
The new pump station is located on Saddle Island on the shores of Lake Mead and required significant underground work, posing challenges and risks. see DRILLING page 28

A grade separation project north of Los Angeles is calling for a different approach than many of the other Alameda Corridor-East Projects (ACE). Crews working on the Fairway Drive grade separation project, one of 19 separation projects in the San Gabriel Valley, will not only depress the roadway, but raise the railroad tracks, as well. “In the past, we mostly separated the roadway and tracks by depressing the roadway, said Charles Tsang, senior project manager of the San Gabriel see ACE page 44
