Southern Water Supply Boulder, Colorado

With approximately 96,000 feet of 36-inch diameter and 14,000 feet of 32-inch diameter raw water transmission pipeline, Southern Water Supply construction also required appurtenances running from Carter Lake in Larimer County south to Boulder Reservoir in Boulder.

Managing Water Pipeline Construction Across a Variety of Environments

Otak’s construction management team oversaw the roadway reconstruction and reclamation efforts for this project, which involved the installation of a 20-mile raw water pipeline that extends from Carter Lake to Boulder Reservoir. The alignment crosses open space, agricultural lands, roadway, streams, wetlands, and ditches. Some areas are environmentally sensitive and have very specific revegetation requirements. In particular, the stream crossings and wetland reclamation must be carefully monitored for compliance with 404 Permit requirements and floodplain regulations.
