Water Quality Laboratory<\/em><\/figcaption><\/figure><\/div>\n\n\nSince 1993, Parsons has provided program and construction management services to the Southern Nevada Water Authority (SNWA)\u2014the agency responsible for addressing Southern Nevada\u2019s water needs\u2014on its major capital program. <\/strong>Our very first assignment was to develop a phased plan so new facilities would come into service just before they were needed. Key features of the capital improvement program include:<\/p>\n\n\n\n\n327 miles of pipeline<\/li>\n\n\n\n 13 pumping stations<\/li>\n\n\n\n 16 reservoirs and forebays<\/li>\n\n\n\n 2 large new intakes in Lake Mead<\/li>\n\n\n\n 6 large hard rock tunnels \u2013 4 drill and blast and 2 TBM up to 15 Bar pressure<\/li>\n\n\n\n 4 concrete lined access shafts as deep as 600 feet<\/li>\n\n\n\n 56 blind bore well shafts up to 91-inch diameter<\/li>\n\n\n\n A new ozone\/direct filtration plant<\/li>\n\n\n\n The addition of ozone treatment to the existing water treatment plant<\/li>\n\n\n\n Turnouts (distribution points) to regional water retailers<\/li>\n<\/ul>\n\n\n\nDeveloping A Project Control System<\/h3>\n\n\n\n To manage the requirements of such a large and changing program, we developed a unique project control system that linked to the overall project schedule to track spending on every contract. This system also provided transparency for SNWA to monitor how its ratepayers\u2019 money was spent as construction proceeds. Our other innovations and accomplishments on this program include:<\/p>\n\n\n

Lake Mead Intake No. 3<\/em><\/figcaption><\/figure><\/div>\n\n\n\nA programmatic environmental impact statement that covered the entire program, allowing projects to be built without further individual environmental studies<\/li>\n\n\n\n A detailed analysis that divided contracts into similar types of work and size. This has resulted in excellent prices<\/li>\n\n\n\n Design suggestions that resulted in similar structures and equipment that saved more than $29 million in construction costs<\/li>\n\n\n\n Value engineering on three of the major facilities \u2014 the two treatment plants and the intake in Lake Mead\u2014resulting in estimated savings of $35 million<\/li>\n<\/ul>\n\n\n\nWe recently provided planning, project development, design management, and construction management for SNWA\u2019s new Intake No. 3\u2014a deep water intake that will provide continued access to water from Lake Mead as a historic drought and declining lake levels threaten the operation of the other two intakes.<\/p>\n\n\n\n
Comprehensive Water Management<\/h3>\n\n\n\n We currently provide program and construction management services for the Intake No. 3 Low Lake Level Pumping Station (L3PS), which will deliver water from the recently completed intake to SNWA\u2019s two water treatment facilities. The project includes the new pumping station, 144 inch-diameter aqueducts to connect to existing facilities, and 69-kv electrical service to the pumping station. L3PS will have a total pumping capacity of 900 million gallons per day.<\/p>\n\n\n\n
