Construction of site infrastructure - 2005 through 2008
December 2008 A protective membrane covers the liner system installed for Cell 1 of the Mesquite Regional Landfill. The 5-foot-thick liner installation was completed by Sukut on December 12th. The membrane protects the liner from the elements until landfill operation begin.
December 2008 Natures Image crews clear the shrubs from the 150-foot-wide corridor in which the rail spur for the Mesquite Regional Landfill will be built. The spur will extend about 5 miles from the Union Pacific main line near Glamis to the landfill.
November 2008 A three foot thick layer of dirt is placed to protect the composite liner system below from the heavy equipment that will be used to compact and bury trash. The composite liner system includes a gravel layer, high density plastic liner, and an engineered clay liner.
November 2008 Tortoise proof mesh is added to a chain link fence along the perimeter of the landfill. The tortoise mesh is installed 12 inches below ground and extends 24 inches above ground to keep desert tortoises out of the active landfill area.
October 2008 A third party inspector is hired to inspect each of the welds joining sections of high density polyethylene plastic liner. This plastic liner is the impermeable portion of the composite liner system and requires extensive field-testing to ensure its integrity.
October 2008 During construction, sand bags and rolls of liner material are used to keep liner in place.
September 2008 The composite liner system being constructed at the Mesquite Regional Landfill includes a gravel layer that would transport liquids coming down through the refuse. Any liquids collected would then be pumped out for treatment and disposal.
September 2008 Two more groundwater wells were added to the exisitng groundwater monitoring system at the Mesquite Regional Landfill. The groundwater is sampled, analyzed, and the results reported to the Regional Water Quality Control Board to monitor the integrity of the composite liner system.
August 2008 Administration buildings, security fencing, and storage areas are completed for the operations facilities at the Mesquite Regional Landfill. Granite Construction is the contractor for the project.
August 2008 A trench is dug around the upper edge of the first cell at the Mesquite Regional Landfill as part of the composite liner installation. The edge of the liner will be placed in the trench and firmly anchored in place.
July 2008 Rolls of synthetic liner and geosynthetic clay liner are stacked at the Mesquite Regional Landfill site awaiting installation as part of the composite liner for Cell 1 of the landfill. When complete, the liner being installed by Sukut will be more that 5 feet thick.
July 2008 Large steel canopies, installed by Granite Construction, shade concrete slabs at the Mesquite Regional Landfill that will be used for storage and equipment maintenance.
June 2008 Truck scale installation at the entrance to the Mesquite Regional Landfill is completed in anticipation of the landfill becoming operational by the end of the year.
June 2008 Sukut Construction prepares the subgrade for liner construction. An environmental monitoring system will be located in trenches below the liner to confirm the liner functions properly.
June 2008 The final phase of construction of the modular buildings begins at the Mesquite Regional Landfill. Granite Construction is installing plumbing, indoor electrical service, and completing skirting for the buildings.
