About this file
This is an Engineering Systems Requirements document (ESR D20) for plumbing systems at the P-909 SOF SDVT2 Operations Support Facility at JEB Little Creek, VA. The document details comprehensive plumbing requirements including fixtures, water distribution, and specialty systems.
The specifications require dual function flush valve water closets, manually operated metering faucets for lavatories, emergency eyewash and shower facilities in battery storage areas, and natural gas water heaters for domestic water. The document mandates copper tubing for above-ground piping, PVC for below-ground waste piping, and cast iron for vent systems. Specific requirements include backflow preventers, master thermostatic mixing valves, floor drains with trap primers in mechanical rooms and restrooms, and a compressed air system meeting ISO 8573.1 class 2.4.4 standards. The facility must also include small commercial ice machines in laundry rooms, breathing quality air compressors, and tank fill stations. All installations must comply with International Plumbing Code (IPC) and UFC 3-420-01 standards.
