What is ISO Hauled Water Classification?
The Insurance Service Organization (ISO) ratings are numerically categorized from one through ten. A rating of Class "1" is the highest rating a fire department can receive, 10 being the worst or unprotected. The following information lists the requirements that have been met by the M.E.S., which has enabled them to qualify for a rural hauled water credit.
Mulvane's rural classification for Fire District #12 had been a ISO Class 9 until 2004. In 2004 we were able to reduce this to a Class 8B. The 8B rating is based on the ability to supply 200 gallons per minute for 20 minutes in non-hydrated areas. In June 2008 Mulvane Fire Rescue performed the Rural Hauled Water drill for the ISO, lowering the rating class even further. Mulvane Fire Department was able to demonstrate the ability to provide 500 gallons per minute for 2 hours to any portion of Fire District #12. Final results of this drill were an ISO Class 5, effective December 1st, 2008. Only about a dozen (12) departments in Kansas have done this exercise for the ISO, there are 1,177 rated communities in Kansas!
To receive an ISO rating the following minimum requirements must apply:

Special "Thanks" to all the Volunteers who made this happen!
Dispatch Credits improved from the City evaluation in 2004.
The first timed evolution was to set up the fire hydrant for re-supply. This included driving 200' to the hydrant, laying out the supply hose, attaching the hydrant valve and turning on the hydrant. Time was stopped when water started flowing through the hose. Only the driver & passenger were allowed on this exercise. Our time on this was 41 seconds.
The second timed evolution was to have all the tenders pull up to the dump tank and unload their water. Time was started 200' before the dump tank and stopped 200' away from the dump tank. Trucks had to back up to the tank & off load water, side dumps were not allowed. Mutual Aid companies were required to perform these tests as well. We were only limited by the number of firefighters in this exercise that we could substantiate on a normal structure fire, which in our case was 14. Our 4,000 gallon dump tank was placed in position before the drill began.
The third timed evolution was to have all the tenders resupply at the fire hydrant. Time was again started 200' prior to the hydrant and stopped after the truck drove away 200'. The driver, passenger & a water supply officer was all that was allowed to help with this drill.
Mutual Aid tenders from Udall (CCFD #4) and Belle Plaine (SUFD #9) assisted us in these drills. Times from SCFD #1 were already in the ISO database. Derby Fire Department provided an Engine Company on standby in case of an alarm since our resources were completely used up during the drills.
The fourth timed event was a modified NFPA 1410 drill. Engine #402 and Tender #408 had to come in from 200', set up the dump tank, advance a 2.5" hose line and have water flowing at draft from the dump tank. This had to be done within 5 minutes. We were able to accomplish this in a record time of 2 minutes, 19 seconds. We were allowed to utilize 14 firefighters on this exercise.
