What's on Your Tanker? #40 - Tanker/Pumper - Stockton Springs, Maine

President Mark Davis, January 26

Water hauling rigs truly vary from region to region throughout the United States. Many variables come into play when we look at how we use our water haulers: topography, water source distance and access, availability of mutual aid rigs, versatility of the piece, etc. Rigs are often designed and equipped to best serve the response district which they serve. During our 2015 seminar in Prospect, Maine ... (Full Story & Photos)

What's on Your Engine Company #09 - Suction Inlet Control Valves Make a 2200 gpm Flow Achievable

President Mark Davis, January 19

In our seminars we always discuss the importance of being able to control the flow into your pumper's suction inlets during drafting operations. Such control can be accomplished in a number of ways using internal or external control valves. At our 2013 seminar in Plainville, New York, Plainville Engine 4 (1750 gpm) used three, 6-inch suction inlets to hit a peak flow of 2200 gpm from a 6-dump tank ... (Full Story & Photos)

Three, 6-inch suction lines helped this pumper produce a 2200 gpm flow from a 6-dump tank set-up.

While not as efficient as getting a full-size pumper to water's edge, this open-relay operation was able to get tankers loaded fast and back on the road to the dump site.

Fill Site Operations #13 - Grass Rig Used to Support Open Relay Tanker Loading Site - Kansas

President Mark Davis, January 12

At our 2013 seminar in Ottawa, Kansas we had the chance to use a grass rig (brush truck) to support an "open relay" tanker (tender) loading site. The operation was part of our 2-hr water supply drill which culminated the 16-hr Rural Water Supply Operations Seminar that we delivered for the Franklin County Firefighters Association. The water source was a large pond located at a local church camp ... (Full Story & Photos)

What's on Your Tanker? #39 - Vacuum Tankers Load from a Dry Fire Hydrant

President Mark Davis, January 05

During our 2013, 16-hr Rural Water Supply Operations Seminar in Ashville, NY we had the opportunity to load a couple of vacuum tankers using a dry fire hydrant. As noted in a number of discussions in our Members Area, perhaps the greatest advantage of these type of water hauling rigs is the ability to self-load at NFPA 1901 design rates without the need for a pumper at the water source. The photos ... (Full Story & Photos)

Fill Site Operations #12 - Using What You Have

President Mark Davis, December 29

We show a lot of "big water" operations using "big water" stuff....but not everybody has that stuff. When faced with a water supply operation that can't wait, figure out how to use what you have to the best of its ability. These photos from our 2012 seminar in Sumter County, Alabama, show a 1,250 gpm pumper drafting through 40-feet of 6-inch suction hose and loading tankers at a rate of 1,000 gpm ...

Dump Site Operations #26 - Multiple Suctions - New Hampshire

President Mark Davis, December 15

A few photos from our 2013 seminar in Chichester, New Hampshire. The folks did a nice job of getting multiple suctions into the primary dump tank so that they could maximize their drafting capacity. Chichester 54-Engine-1 (1500 gpm) operated as the dump site pumper and supported a water supply operation that started with a "rural hitch." When operating as the water source pumper work to get as much ... (Full Story & Photos)

Always work to get multiple suction lines in place when operating as the drafting pumper at the water source.

Dry Fire Hydrant Design #54 - A Training DFH - Autagua County, AL

President Mark Davis, December 08

Looking back through some more of our older photos we found a few that we took from our 2010 rural water supply seminar in Autagua County, Alabama. For the tanker shuttle drill on Sunday, Stan Merrett from ETT Fire brought his "demo" dry fire hydrant with him for our use. The dry fire hydrant prop is portable and let's folks see what a basic dry fire hydrant looks like and how it works. We used it ... (Full Story & Photos)

What's on Your Tanker? #38 - Shelby FD Tanker 113 - Shelby, AL

President Mark Davis, December 01

Going through some photos from our 2012 seminar in Four Mile, Alabama we came across these photos of a 2,000 gallon tanker built on a repurposed power company line truck. The boom was removed from the heavy-duty chassis and a 2,000 gallon tank was installed. The rig worked pretty well hauling water at our drill and was set-up to support forestry efforts (250 gpm pump plus hose reel.) We don't know ... (Full Story & Photos)
