Landfill Design

AquAeTer was retained by this client to prepare the landfill design and specifications for a new 1.5 million CY hazardous waste disposal cell, and to prepare the design and specifications for the final cover for Cells #11 and 12. The new cell was designed, permitted, constructed, and approved for waste disposal by NV DEP within a 15-month period. AquAeTer also provided construction quality assurance services for all earthwork and liner construction, and provided the construction certification report. This final cover was the first evapo-transpirative cover to be approved for a lined Subtitle C landfill.

  • Design and permit revision planning with client and NV DEP
