Dry Fire Hydrant Design #85 - Good Work by the South Salem Fire District!
President Mark E. Davis, January 15
Congratulations to the folks at the South Salem Fire District in Westchester County, New York on completing another dry fire hydrant installation. In January 2013, we completed a comprehensive water supply study/ assessment for the fire district. Since then, the fire district and fire department have worked hard to make improvements to their fire protection water supplies; they developed a plan and ... (Full Story & Photos)

Haulin' Water - 42 Years Ago - Nikiski, AK - Fill Site Operations
President Mark Davis, January 08
We've been doing this work a long time...23 years under the GBW Associates, LLC moniker....a bunch of years prior to that with no moniker. July 1984 had us in Nikiski, Alaska with Larry Davis and Chief Billy Harris working on hauling big water for the folks on the Kenai Peninsula. Several, large industrial complexes populated the area and the need for alternative fire protection water supplies was ... (Full Story & Photos)

Loading tankers at an incredibly fast rate. Crews were credited with a 1,000 gpm for the ISO 2-hr water supply drill. Something pretty much unheard of in that era.

Our first ever DFH install in Michigan was one of the many highlights for the year.

2025 - It's a Wrap!
President Mark Davis, January 01
Many, many thanks to everyone who helped make 2025 a banner year for us here at GBW Associates, LLC. Our training seminars took us to places far and wide such as Athens, Alabama; Wheatland County, Alberta: Fairlee, Vermont: Floyd, Iowa: Watertown, South Dakota; and, Ottawa, Kansas just to name a few. Along the way we amassed just under 8,000 student hours of instruction and hauled around a million ... (Full Story & Photos)

What's on Your Tanker #63 - External Jet Dump
President Mark Davis, December 25
From the Larry Davis, Jr. Collection, a photo from somewhere in New York State showing an external jet dump on a tanker. This is probably a circa-1980s photo and this technology was pretty innovative at that time. Work was underway on many fronts to figure out how to make tankers dump their water faster. The external jet dump was one of the innovations that could be applied to an existing tanker. ... (Full Story & Photos)

Innovation in the works! Hopefully, this photo means something historical to NY water supply folks.

Dry Fire Hydrant Design #84 - Diagnosing an Air Leak
President Mark Davis, December 18
No rocket science here. A fair amount of our work involves troubleshooting dry fire hydrant and fire hydrant problems and developing recommendations/plans for repair or replacement. For dry fire hydrant suction heads, a common issue with the PVC/metal heads is failure of the sealant or gasket where the metal head is threaded into the PVC fitting. Some times this is production QC and sometimes it ... (Full Story & Photos)

Dry Hydrant Design #84 - It Is Fixed!
President Mark Davis, December 11
In our last News Story we spoke about one of our bridge-mount dry fire hydrant systems that had a component failure; that system on Newport Road in Woodbine, MD was installed in 2006 and served for 19 years. The design of that system was our original design and used lighter gauge steel components. Since then, all of our designs for the last 15 years have used heavier duty, hot-rolled steel for the ...

The old system. The cradle arm corroded and broke.

The old and the new. All of our installations since 2009 use 1/4-inch steel for component design.

Dry Fire Hydrant Design #83 - It Finally Broke!
President Mark Davis, December 04
After 19 years of service, one of our earliest bridge-mount dry fire hydrant designs and installations finally gave up and called it quits! Back when we got started we used some lighter weight steel to make our parts and we did not have a good feel for how long they would last out in the elements. This past summer, the cradle arm on one of our 2006 installations finally failed due to corrosion. ... (Full Story & Photos)

Dry Fire Hydrant Design #82 - Bridge-Mount Installation - Richford, Vermont
President Mark Davis, November 27
September was a busy month for the dry fire hydrant installation program. On the 9th, an installation was completed in Richford, Vermont on East Richford Slide Road, a couple hundred feet from the Canadian border. The project received partial funding through the State's grant program. The site was a bridge over Lucas Brook, and the new bridge mount replaced a fixed-pipe installation that had become ...

Just a few hundred feet from the Canadian border, this installation provides access to fire protection water in East Richford Village.
