About this file
This file contains site visit photos showing backflow preventer equipment and water supply infrastructure at what appears to be a government facility. The images document three water systems: a 6" non-potable water line, an 8" city water main, and a 10" fire water main, each equipped with Watts backflow preventers and regulators. The equipment includes model 909 reduced pressure backflow preventers rated for maximum 175 PSI and 110°F, with UL classification tags from Classified Underwriters Laboratories.
The photos show both current and pre-2017 configurations, with the equipment originally housed in underground vaults. The vault images show blue-painted backflow preventers, gate valves, and associated piping installed in concrete chambers. One photo shows an above-ground concrete pad with block walls, presumably the new installation location. The documentation appears to be related to a Bureau of Reclamation project to replace or upgrade these backflow prevention systems.
