- Cheyenne Southern Water Transmission Main Phase 2
Burns & McDonnell designed approximately 11 miles of potable water transmission line ranging in size from 42 inches to 12 inches in diameter. This project strengthens the water infrastructure in the southern portion of the City of Cheyenne. The water line is located in utility easements and within existing right-of-way. The water line runs through undeveloped areas as well as city streets. There are two crossings of Interstate 80, one crossing of Interstate 25, two railroad crossings and multiple road crossings.
Coordination and planning with outside agencies was very important to the project and included reviews by the Wyoming Department of Transportation, Laramie County, City of Cheyenne, Union Pacific Railroad, Burlington Northern Santa Fe Railroad, U.S. Fish and Wildlife and the Army Corps of Engineers. The city delayed a street rotomilling and overlay project so the water line could be installed prior to street improvements.
Alternative materials were allowed, including steel and ductile iron, and cathodic protection design was performed for both. Burns & McDonnell is providing all construction management services for this project.
