This is a mechanical layout drawing for a water system installation at Building #138 (Waverley Arsenal Public Works Division, Watervilet, New York 12189). The schematic depicts a plumbing configuration that includes two water softeners (#1 and #2) connected in series via 1.5-inch piping, with the system originating from a 1.5-inch black iron line rising 35 feet to the first floor. The water treatment train incorporates a 2-inch CPVC main line, a 4-inch OS&Y (open-stem-and-yoke) valve, a 4-inch butterfly valve for flow control, and a 1/2-inch drain line for discharge.

The lower section of the diagram illustrates the drainage configuration, featuring a 3-inch thresholdlet connected to a 4-inch flange with an 8-inch sump basin. The basin incorporates dual backflow prevention mechanisms and maintains a 2-inch vertical clearance. The system is designed with a 5-foot horizontal run and 15-foot extended line to the butterfly valve. This technical drawing establishes the specifications for water distribution and treatment infrastructure improvements required for the facility.
