About this file
This is a site plan drawing for the Furnace Creek Wastewater Sewage Lagoon System project at Death Valley National Park. The drawing (Sheet C4.38, Drawing No. 215, dated January 17, 2025) depicts the layout and modifications for a wastewater treatment facility consisting of three lagoon cells with associated infrastructure improvements.
The project scope includes removing 2,855 linear feet of existing fence and installing 3,239 linear feet of new 6-foot chainlink fence to match existing fence material, along with a double swing gate at the headworks area. The work requires grading and installation of riprap, construction of a proposed fence line and headworks structure, and grading of existing Cell #3. The contractor must perform all fill excavation, soil mixing, and stockpiling operations within a designated soil quarry and stockpiling boundary, with stockpiles confined to this area. The design incorporates three pond level gauges (installed at each cell with red dashed outlines shown), a proposed gangway and floating dock system, surface aerators, mooring lines and masts, and connections to existing infrastructure including an 8-inch DIP and 8-inch SDR 35 PVC pipe. Additional work areas include a headworks area (referenced on Sheet C4.39), riprap grading (Sheet C4.42), and identification of potential temporary pit areas and site-generated fill mixing zones. The project is managed under PMIS/PKG No. 143, with technical review by M. Whelehon and design by C. Weaver and V. Neary.
