CJD Powerhouse Sump Technical Drawing - 950088.pdf

This technical drawing is a schematic for a drainage sump oil skimmer arrangement for the U.S. Army Corps of Engineers, specifically for the Chief Joseph Dam project. The document is labeled as drawing SK-CJP-349 and provides a detailed layout of an oil skimmer system's spatial configuration, showing various components and their positioning within a designated area. The drawing includes notations for existing equipment, access points, and a detailed view of the oil skimmer arrangement, with markings indicating specific measurements and spatial relationships critical to the installation of the oil skimmer system.

The drawing is directly related to the federal contract opportunity W912DW25R0024, which seeks an all-in-one oil skimmer and day tank replacement for the Chief Joseph Dam. The technical specifications require a vertical tube type skimmer with an integrated decanter and stainless steel collection tank, capable of recovering 65-100 gallons per hour, with specific requirements for operation in a sump with fluctuating water levels. The system must be mountable on a skid, operate continuously, and fit within a 30-inch by 74-inch footprint, with power requirements of 120 VAC single-phase and a NEMA control box for managing system components.
