Meeting Omaha’s water needs for the next 50 years
Increasing Omaha’s water treatment capacity by 40%
Alberici constructed a 104 MGD greenfield water treatment plant, increasing the Metropolitan Utilities District’s treatment capacity by 40 percent and meeting Omaha’s drinking water needs for the next 50 years. This mammoth project, with buildings enclosing a total of 630,000 square feet, employed more than 450 craft personnel at peak construction.
Building a massive water treatment facility
Major components include the main water treatment facilities, 15 million gallon underground disinfection reservoir, high service/backwash pump station, gravity thickeners, residuals processing building, generator building, and surge control station. Alberici also installed equipment in the plant including the vacuum cleaning system, sedimentation and thickening equipment, and chemical mixing and injection equipment.
Coordination of large quantities
Over 1,000,000 CY of backfill, 104,000 CY of structural concrete, and 14,000 tons of rebar were needed for the project. Given these massive quantities, careful coordination and sequencing of the concrete foundations, walls, elevated decks, and backfill activities were vital.
Meeting the schedule despite extreme weather
The Alberici team delivered the project on time despite two severe winters and a 100 percent increase in average rain fall during the final year of construction.
