CJD Powerhouse Sump Techincal Drawing - 950087.pdf

This technical drawing is a detailed schematic for a drainage sump oil skimmer system designed for the US Army Corps of Engineers at Chief Joseph Dam. The drawing, labeled SK-CJP-350, provides comprehensive engineering specifications for an all-in-one oil skimmer system, including detailed views of equipment arrangement, hole location, and concrete floor drilling plan. Key technical specifications include a vertical tube-type skimmer with an integrated decanter and stainless steel collection tank, capacity range of 65-100 gallons, automatic oil recovery and water separation, and a free-floating closed loop oil collector tube designed to operate in a sump with fluctuating water levels between 15-35 feet from the finished floor. The system requires 120 VAC single-phase power, features a NEMA control box, and is designed for continuous 24/7 operation with integrated alarm and indicator systems.
