Owens Lake Dust Mitigation Project, Phase 5

  • Phase 5 implemented over 6.5 miles of shallow flooding dust control, shown above.

  • Twenty-two inch High-Density Polyethylene (HDPE) piping carries brine water between the lakebed’s dust control areas.

  • Three pump stations were constructed during Phase 5 to store, treat and transport water throughout the lake bed.

  • A series of turnout stations, similar to the one shown above, were constructed to strengthen the site’s infrastructure.

  • The 22,000 square-foot Sulfate Administration Building, seen here, was constructed during Phase 5.


Phase 5 of the Owens Lake Dust Mitigation Project involved both remediation activities and infrastructure development and construction.  Multiple facilities were constructed, including a 10,000-square-foot administration and 22,000-square foot operations building. Major work included the construction of approximately 26 miles of roads and berms, laser land leveling and grading and the installation of over 40 miles of 12-inch diameter subsurface perforated drain pipe and  high-density polyethylene (HDPE) conveyance pipe. In addition, seven control valve facilities, multiple supervisory control and data acquisition (SCADA) facilities and five pump stations with cathodic protection systems were constructed.

KDG’s Responsibilities

KDG served as the prime construction manager during Phase 5 of the project. Our team of resident engineers, inspectors, project control staff, technical specialists and safety professionals partnered with LADWP to monitor and coordinate all construction activities. Our staff was responsible for schedule and cost control of the construction contract, processing change orders, handling pay applications and tracking construction progress. Additionally, quality assurance and safety staff performed all onsite quality inspection supervision, technical inspections, site safety monitoring, and reporting.
