About this file
This is a site plan drawing for the Furnace Creek Wastewater Sewage Lagoon System located at Death Valley National Park. The drawing (Sheet C4.38, dated January 17, 2025) depicts the overall layout of a wastewater treatment facility comprising three lagoon cells, with associated infrastructure and site improvements.
Key project elements include: removal and replacement of approximately 2,855 linear feet of existing fence with 3,239 linear feet of new 6-foot chainlink fence with double swing gate; construction of headworks infrastructure; grading of existing Cell #3; installation of pond level gauges and aerators; grade and riprap work for erosion control; and mooring line and mast installations. The contractor must perform fill excavation, soil mixing, and material stockpiling within designated soil quarry and stockpiling boundaries, with stockpiles confined to the quarry area per Section 31 23 00 "Earthwork," Paragraph 3.6. The site plan identifies potential quarry areas, site-generated fill mixing areas, temporary pit run and dredge fill stockpiles, and a service road connection to existing cells. The project is designed by C. Weaver, with technical review by V. Neary and M. Whelehon, under PMIS/PKG No. 178069 and Drawing No. 01-318717.
