This is a technical schematic diagram titled "Domestic Water Riser Diagram" prepared by the U.S. Army Engineer District, Baltimore, Corps of Engineers. The diagram illustrates the domestic water distribution system for a multi-floor building, showing the piping layout and connections across three floor levels (1st Floor, 2nd Floor, and 3rd Floor). The schematic is marked "Not to Scale" and includes detailed annotations for pipe sizes, valve locations, and connection points throughout the system.

The diagram depicts the water supply infrastructure with multiple risers distributing water vertically through the building structure, along with associated shut-off valves and check valves positioned at strategic points. The notation indicates this is a revised drawing (marked as "Revised as Built"), with revision information documented in the title block. The drawing number is F-721-90-12 with a sheet number of 155, establishing this as part of a larger construction or facility documentation set. The document references standard specifications and notes regarding equipment sheets and applicable standards, typical of federal construction documentation and technical specifications for building systems.
