    Default Grant Info for Large Diameter Hose

    Can anyone shed any light on specific NFPA guidelines (should I look at 1901 or something else) or successful narratives for Large Diameter Hose? We are considering applying for LDH and related appliances. We currently have no LDH at all, and are debating what total length to apply for. We are a rural department with no city water (hydrants). Any input or info would be appreciated. Thanks!

    NFPA 1142 the Standard on Water Supplies for Suburban and Rural Fire Fighting. ISO also has many recommendations/requirements that can be used for arguing for sustained water flow. Besides the fact it's easier to pump 1-5" for 1000gpm than 2-3" lines. Friction loss is not our friend.

    No problem. We aren't Abbott and Costello, but it works.

    Think thru what your objective is, not how you are going to use a particular tool. LDH is a tool to solve a problem not the objective.

    We also are a rural dept 35mi2, pop 350, no hydrants (or municipal water supply) or local water supply (minimum 7mi each way to refill tankers). Nearly done with Phase 1 of water supply improvement program. We are using LDH to solve our problem in meeting ISO fire flows in our small town and some rural areas. Last summer we created/dug/installed a 350000gal fire pond/lagoon w/dry hydrant. This spring will be installing an electric pump (1500gpm+) with hydrant. 2000ft of LDH will reach any structure in town. At present mutual aid will pump the LDH our pumper/tanker will respond to the scene. When pump @ fire pond is done will not need the mutual pumper. LDH is essentially a portable fire main.

    We actually sourced our LDH from US Navy surplus (5000ft of 6"). Mount/carry on a hosewagon/trailer with a reel (see manure handling drag hose equipment). Towed/laid by our utility pickup when needed. The additional 3000ft of LDH will allow us to move a large vol of water to some of our large rural problem areas. In particular a couple of large hog barns (50000ft2/2500gpm). This was a small part of our 2004 equipment AFG (LDH fittings etc.

    Ph 2 of our water project is developing rural water storage lagoons and tanks to act as water sources so we will not have to depend on the inadequate tanker fleet in the area, can lay LDH. A rural water system (15" main) is also going across one end of our fire district and now attempting to force them to install hydrants.

    Where ground/stored water supplys are not available in rural area we will lay LDH from the structure to the road (frequent 1000ft drives) where a supply pumper with multiple portatanks/tender dump site is located. Another good use of LDH. Our pumper now carries 5" Storz LDH for use with ground mount monitor or for local fire ground distribution from the 6" "main"

    LDH also can solve problems with tender fill at hydrants (pressure or dry) or can reduce tanker travel distance (lay a mile of LDH from water source to best available local tender fill point, can reduce congestion/inefficience of tender fill at the water source, solve inefficient tender route due to less than optimal location of water.

    The primary references you need to work with concern the ISO standards. www.isomitigation.com and www.isoslayer.com Also possibly applicable are the AWWA standards which pertain to hdyrant location etc.

    Standards are hydrants to meet ISO fire flows within 300ft of structure and max of 500ft spacing between hydrants. OR FD demonstrates the ability to meet ISO fire flow standards using alternative water supply - as thru use of LDH and alternative source of water source.
