CJD Powerhouse Sump Techincal Drawing - 950087.pdf

This is a technical drawing from the U.S. Army Corps of Engineers showing detailed specifications for a drainage sump oil skimmer installation at Chief Joseph Dam. The drawing (SK-CJD-350) includes multiple views and details of the equipment arrangement, including a circular detail view of the equipment setup, a "View B-B" cross-section showing the tank with pump and controls, and specifications for concrete floor drilling and hole locations.

The drawing provides specific installation details for mounting the skimmer system to a concrete floor, with precise measurements for bolt hole locations and spacing. It shows the arrangement of key components including the skimmer, decanter, slide pin, and associated mounting hardware. The drawing indicates the equipment must be properly anchored to the floor using stud bolts and includes detailed dimensions for proper placement. This technical document appears to be part of a larger procurement package for replacing the powerhouse drainage sump oil skimmer and day tank system.
