Dry Fire Hydrant Design #11 - Swivel Mount Design - Westminster, MD

In late August 2017, we installed one of our bridge-mount dry fire hydrants in Westminster, MD. The installation used our saddle-mount bracket that uses a "non-destructive" process to attach to the bridge wall. (No holes are drilled into the bridge structure.) The location chosen for the Westminster site was a small bridge over a stream. The stream provided ample water supply and the bridge provided a lift under 10-feet. Once the installation was complete, a 1500 gpm pumper was used to conduct the installation performance test. A flow in excess of 1,000 gpm was achieved.

The GBW bridge-mount design has become increasingly popular where the installation of a permanent suction pipe is impractical.
