Frank R. Bowerman Landfill Groundwater Protection System, PHS 8B - 2

Sukut is performing work on the Groundwater Protection System project, consisting of a 5 million cubic yards of compacted fill placement to buttress the North Landslide Complex at the Frank R. Bowerman Landfill. The new support will stabilize the expansion of the new 1.1 million square feet of composite liner system which will be constructed by Sukut along the slope face of the buttress fill. The scope also includes landfill gas collection system construction, drainage, and 30,000 square feet sedimentation basin improvements.
