I dont know how many of you have heard of the Water Master Tankers that are now E-One but if your department is looking for a tanker it would be well worth it to check into. We got a Water Master before E-One bought the company from a guy in our Fire Dept. They are amazing.
We use our tanker to suction water from ponds, pools, creeks, and etc. in no time flat. To fill our 4000 gallon tank it takes roughly a min or two from suctioning from a pond or such. A fire Hydrant is a little longer but not much. Also we have a fire pump on ours which we can suction water and pump at the same time. We operate everything from inside the truck and we can choose one of three outlets to dump the water.
Just wanted to throw this out and let ya look at them and check them out. Look into them.

I think the concept is pretty interesting, my deputy and I were just talking about it the other night.
What is the "maximum" hose length and/or lift you can suction through with this set-up?
We have some large ponds that are 15 feet from road access that I've been curious about accessing. We've played with turbo draft, but thought this might get us "drafting" quicker.

Watermaster has a couple of decent videos on youtube. As I recall 60ft is no problem (if you have enought 6" PVC suction hose).
I'm not sure getting set up is really going to be quicker than the TD Will get bigger flow than thru one TD (and don't need a draftsite pumper).

I'm not going to argue E-One vs. Firovac but a vacuum tanker is what you need if you really want to move water.
Our department has a Water Master that was delivered in 2005. We looked at both Water Master (now E-One) and Firovac. I was only back in time to see Firovac and I couldn't quite wrap my head around the vacuum tanker concept but after seeing one in action I am a believer! We wanted the Firovac to draft from our dry hydrant but it was configured for 5" and the tanker had 6". They said not a problem, butted the two different sizes of hard suction together and ran duct tape around the "connection". Firovac was drafting faster that way than we had ever done with an engine.
The key item is the fact that instead of having a relatively small primer motor like we have on traditional fire apparatus these tankers us vacuum pumps. Whereas the primer will fail due to a air leak the vacuum pump doesn't really care. It is designed to move a lot of air and therefor can establish a draft in places you wouldn't even think about attempting with an engine. We have drafted, without a problem from on top of a bridge where the water level was about 6' below the bottom of the bridge. Not the best draft scenario but it worked.
Cottonboy is correct, these tankers actually fill slower from a hydrant that draft. Like I said, I'm a believer in the vacuum tanker concept. They eliminate the need for a fill site engine, with just a couple guys you can move more water than several conventional tankers. The benefit is not only in the fill time, which is significant, but also in the dump time. You can reverse the vacuum pump and pressurize the tank and dump at the same rate as you filled. They can also be operated as a conventional tanker if you want by opening the vent.
It is my belief that tankers should have a fire pump (500 gpm minimum) to relay pump when needed. Using a vacuum tanker we have caught a draft and then relayed with an unlimited amount of water to our suppression engine. You can't beat that for rural ops.
They cost more than a traditional tanker but the money you spend will make your suppression capabilities that much better because you will have water to use. The only suggestion I have to offer is that you ensure the tank is lined to eliminate electrolysis over time. Something I really wish we had done.
If you are looking at replacing a tanker please take a look at the vacuum concept. It is definitely worth the time and money in my opinion.

They aren't very popular around here. (Central Oh.) Most depts. opt for more traditional tankers. We just ordered a Pierce pumper tanker because it will be the 2nd engine on fires and 1st if the engine is out of service. BTW, Vacuum tankers can cause damage to water mains if not used properly. You can't take all the pressure off of the mains and have negative pressure or you can collapse the water mains.

That is worth saying twice. I probably didn't stress that enough. The vacuum tankers load and unload at the same rate due to the fact that you can pressurize the tank and pressure dump.
Another benefit is that if you are concerned about ISO they get credit for the full load because they don't slosh any out. If you operate in cold temps they are great because they don't slosh water out which becomes becomes ice on the road.
The only way you could collapse the mains is if you connected the hard suction to the hydrant. Since hydrants usually produce pressure hard suction is not recommended.

Oldies but goodies
Some information is old but still good.

I dont know of anyone hooking a hard sleeve up to a pressurised hydrant - vacum or cent pump. Like fire info said - by using that technique - even a weak hydrant can be utilized.?

When we were looking at replacing a back up tanker I did speak with Firovac quite a bit and learned that tank lining was standard. As I said, something I would recommend.
Regarding your pump discussion with the boss. I'm assuming that you currently run without a pump. Do you have a problem with freezing? We either start the pump when we leave the station when it's cold or engage the pump when we get on scene to keep water moving.
Our tankers all have two 200' 1.75" preconnects "just in case" since they are on top of the pump house and out of the way until you need them. There have been several occasions where the preconnect came in real handy. My opinion would be that you only need one but then you could also put 3" up there to quickly deploy for relay pumping.
Our vacuum has 50' of 3" with Storz couplings preconnected, rolled and stored so both couplings are on the same end. When we need to relay pump you just grab the coupling and go to the intake. Works great for refilling grass rigs or nursing an engine.
Have a good one,

No problem with the current tanker( Converted fuel oil truck) it has a 250GPM portable but it isn't hooked up. No issues with freezing, we antifreeze our pumps after we drain 'em, His concern is that the rig might get used for an attack piece if it had a Fire pump.To me,that's a Policy and training issue,easily handled.

Great thread! Lots of good info and ideas.
On a side note,
Has anyone experimented with "fill lines" aka a 3" line with a 2.5" NST female on one end, and a 3" storz on the other?? It seems that more and more direct tank fills are being specced with 3" storz couplings. This seems like it would be a time saver for fill sites- either off a hydrant, a pumper, or a manifold. Would be nice for those foam ops, like with an around the pump system etc, that can't have much intake pressure too. Same for nurse ops, if your attack engine is so equipped.
One could store them as donut rolled pre-cons ( on the tank fills), in a fender mounted tray, in a tanker crosslay, or in a compt rolled up w/both couplings on the outside.
It would save having to fool around with adaptors, and make the make and breaks quicker on the units being filled.
