Dry Fire Hydrant Design #46 - Graceton Road - Whiteford, MD

President Mark Davis, July 15

Another one of our bridge-mount dry fire hydrant installations in Harford County, Maryland....this one in the Whiteford area on Graceton Road at Jacks Hole. The bridge was State owned and the new installation replaced a fixed-pipe installation that had silted over. This installation was completed in June 2021 and produced a flow of 1067 gpm during the performance installation flow test. Elevation ... (Full Story & Photos)

The performance flow test produced a 1,067 gpm flow with 13 feet of lift at 390 feet elevation.

Dry Fire Hydrant Design #43 - Macton Road - Darlington, MD

Here is another one of our bridge-mount dry fire hydrants that we installed last month in Harford County, Maryland. This installation was done on Macton Road over Broad Creek in the Darlington area of the County. Elevation at this location was 240 ft and the lift was 14.5 feet. The new installation replaced a fixed-pipe installation that no longer worked due to the strainer being silted in.

Dry Fire Hydrant Design #42 - Glen Cove Road - Darlington, MD

President Mark Davis, June 24

Earlier this month we completed several DFH installations in Harford County, Maryland as part of their fire protection water supply source development program. Many of the installations replaced "fixed-pipe" DFH systems that had silted in over time due to sediment runoff into the stream.

The photos in this news story show our installation on Glen Cove Road over Peddlers Run in the Darlington area ... (Full Story & Photos)

Dry Fire Hydrant Design #41 - Part 3 - Cecil County, MD

President Mark Davis, June 17

The final piece of our bridge-mount DFH installation project in Cecil County, MD was to remove the old DFH riser. The old system was the reason we were there in the first place; that design had a fixed-pipe buried in the ground terminating in the stream and outfitted with a barrel strainer. The stream and Mother Nature simply won that contest and the barrel strainer became silted in to a point of ... (Full Story & Photos)

Dry Fire Hydrant Design #41 - Part 2 - The Flow Test - Cecil County, MD

President Mark Davis, June 10

On June 6th we were able to flow test our Fire Tower Road bridge-mount dry fire hydrant installation in Cecil County, Maryland. Using Community Fire Company of Rising Sun's Engine 813 (2,000 gpm), a flow of 1,093 gpm was achieved using a Hose Monster flow diffuser as the measurement device. The test hit our goal of 1,000 gpm but most likely could have been higher....however, we stopped the test ... (Full Story & Photos)

Dry Fire Hydrant Design #41 - Part 1 - Cecil County, MD

President Mark Davis, June 03

Last week we completed another bridge mount dry fire hydrant installation in Cecil County, Maryland. This installation replaced a fixed-installation that had "silted in" due to the sediment run-off into the stream. The bridge was owned by the County and thus permissions were easily obtained; especially since this was our fourth bridge mount installation there. Lift was under 15-feet and water quality ...

What's on Your Engine Company #03 - Keeping It Simple...Again

President Mark Davis, May 27

We are always fans of keeping things simple when it comes to operating a fire truck on the emergency scene. We recently got to see Jarrettsville VFC's (MD) Engine 713 in action drafting from one of our bridge-mount dry fire hydrants. While looking over the pumper we liked what we saw on the rear end regarding the markings on the direct tank fill, the rear intake, and the rear discharge connections. ... (Full Story & Photos)
