Attch 5. OWS 2 - Bldg 606.pdf

This document is a set of technical drawings and specifications for environmental systems infrastructure at OWS 2, Building 606, prepared by Remedial Systems, Inc. and TKDA Engineers Architects Planners.

The drawings depict a wastewater treatment and stormwater management system for an airfield group facility in Minneapolis-St. Paul, Minnesota. Key infrastructure components include: a 304th Logistics Group D/V Separator with dual 58-inch diameter tanks featuring influent and effluent distribution systems, sludge baffles, and access ladders; a manway extension and external piping configuration; an oil/water separator system with 10,000-gallon capacity; catch basins and storm sewer manholes for surface water management; and interconnected piping networks for treatment flow. The system utilizes A/R sacrificial anodes for corrosion protection, level sensors, and lifting lugs for tank maintenance. Construction specifications require single-wall tank design with A36 steel, sandblasted exterior surfaces coated with polyurethane, and stainless steel hardware. External piping connections must employ dielectric bushings per manufacturer specifications. The catch basin and manhole schedule identifies specific pipe sizes, invert elevations, and pipe materials (ranging from 5 inches to 18 inches diameter). Additional site details include truck fill stand provisions, pumphouse configuration, water service connections, electrical notes for pump operations, and pavement/curb sections. The drawings are dated November 5, 1993, with revisions noted through 1993.
