Summary

This document is a technical blueprint and engineering schematic for an oil-water separator and drainage system. The drawings depict detailed construction specifications for a fuel storage facility, specifically an "Alter Jet Fuel Storage" system located in Minneapolis, Minnesota, designed by Geo. J. Grant Construction Co. and patented by McGire Industries (Patent No. 4,042,512). The schematic includes multiple cross-sectional views (Sections A-A, B-B, C-C, and D-D) showing the internal components and configuration of the oil-water separator, including inlet pipes, outlet pipes, baffles, tank saddles, concrete pads, vents, and support structures with detailed dimensional measurements in feet and inches.

The technical drawings provide comprehensive installation details for the separator system, including pipe connections, drainage provisions, and structural support requirements. The document specifies various components such as manway extensions with covers, control panels, corrugated metal separators, flanged and threaded connections, and liquid level indicators. The plans indicate this is a standard commercial oil-water separator design with provisions for environmental compliance through proper separation and drainage of liquid waste. All specifications, dimensions, and construction notes are clearly annotated throughout the schematic for contractor guidance and regulatory compliance purposes.
