Broomfield North Area Lift Station and Pipelines

Client: City and County of Broomfield
Completion Date: Nov. 2013 (est.)
Location: Broomfield, Colo.

Summary

Burns & McDonnell is providing design-build services for the North Area Lift Station and associated pipelines located at Highway 7 and Interstate 25 in Broomfield, Colo. The first phase of this fast-track design-build project includes design and construction of the lift station, including all concrete work and wet wells, as well as force mains and other support utilities. Future phases of the development will include additional pumps and appurtenances as the lift station peak capacity will be expanded from 2 million gallons per day (MGD) up to approximately 9.6 MGD. The first-phase work includes the installation of 450 horsepower of pumping with backup power and an oxygenation system to reduce hydrogen sulfide generation in the force mains.

The initial phase of the force main includes 8,000 feet of 12-inch-diameter fusible PVC. Sections of the future force mains also will be constructed, including 2,500 feet of 14-inch-diameter fusible PVC and 5,000 feet of 18-inch-diameter fusible PVC. Other supporting pipelines in the first phase of the project include 4,200 feet of 24-inch-diameter gravity interceptor and 3,100 feet of 12-inch-diameter potable water main.
