lright i need some help figureing out what to do, here is the scope.
i found a tank off an old sewage truck or something, its an 800 gal tank i think its about 12ft long 3-4ft wide. i want to put it on its own trailer for flooding a mud hole when needed. here is what i figured so far
800 gals is about 6680 lbs
tank is about 1500-2000 lbs guessing
i have an old 3/4 truck ford frame i think, would the full floating axle hold up to the weight with some modified springs? i might be able to get a dually rear end also if need be, or another sugestions. i want to keep it relativly cheap, i'm getting the tank for $150
My '93 F250HD has the 10.25" Ford/Sterling full-float axle, and on the door sticker, it's rated at 6084 lbs. I'd think that you would want to go heavier, or use 2 axles, but there's always the brake issue, too--you can't link a trailer's hydraulic system with your tow vehicle's.
How far are you looking at hauling this traier? If you aren't going too far, it probably would work ok, just take it slow. It's a little different if you were trying to run down the raod for a long ways at highway speeds... The trick to it is that the load on your hitch likely wil be more than you want, due to the tippy nature of single axle trailers, and the motion of the water.
I think I'd use a tandem-axle trailer. The load might not get you into trouble by itself but water sloshes around so the weight distribution won't be steady. Hard braking might overload the hitch. Is it wide and flat, tall and narrow, round, etc, and do you know if it's baffled?

not sure on what year or axle the truck was/is. i'm starting to think a tandem trailer would be better also for the weight and because the sloshing, i dont know if the tankl is baffeled or not. a freind has some trailer house axles i can have for the project as long as he can use it as well. the distances full, wouldnt be more than 5 miles
My main concern would be Hepatitis if that is an old sewage tank.
You've probably overestimated the weight of the tank. If it's made out of 12 gauge sheet steel it should weigh about 800#.
Like others have said, it depends a lot on how far and fast you plan to pull the thing. If it was me, I'd load it in an old hay wagon and not worry about tongue weights. It does make it more difficult to back though. On my first load of water I'd dump in about 5 gallons of bleach. I'm not sure that would sterilize it, but it couldn't hurt.
An 800 gal tank sounds like it was from a porta-jon truck. Most septic trucks have much bigger tanks. If it was used for septic or porta-jons it won't have baffles. I agree that a dual axle trailer will be easier to handle than a single, but since you aren't going very far, you could probably get away with one axle. You will just have to mane sure your axle was in the right place to get your tonge weight correct.
1st off, i would find a stearalizing somethinanother and get that sucker bacteria free etc.
2nd, 5 miles isnt that far, your probly in the country, wouldnt worry bout brakes.
(if your in the middle of nowheres, flatland country)
3rd, find an old hay wagon, the trailer with a steering axle in the front and solid axle in the back. if you cant find one, def. go double axle and space them a little bit apart ( as long as you dont plan on goin far)
4th, if your good with a welder, torch, after i cleaned the tank, i would make about a 2ft cirlce hatch hole in the top.
5th, get in the hole you made and make a few baffles.
Realize that this is just waht i would do
last i would try to find a gas motor pump and mount on the trailer. (bout a 3in. hose) and plumb a quick connect to your tank so you could fill up from a pond etc. (wouldnt run up your water/ elect. bill)
I don't know if you've ever seen like a UAP, Helena, FFM tank trailer, but thats pretty much what i described to you.
realize that these are production units, that you would just want to get the ballance of the tank right. thats what i was trying to show you in the pictures
If it is a old septic truck tank it is heavy, probably 3/8 barrel and thicker ends. The tank needs to be that thick to withstand vacume and pressure. I know in NY that anything over 500 gallons you need an endorsement on your license. I would check with your local laws before starting, unless you have an endorsement! But the mud sounds fun!
a friend of mine has a couple trailer axles hes giving me when i get the tank.
i dont think i'm going to worry about cleaning the tank beacuse the truck it sits on is about a mid 70's chevy 2 ton truck and knowing the owner of the salvage yard its been there about 20 years. i have the endorsment but i'm not too worried about that. i have acess to a trash pump i plan to pump out of stream not too far a way like i said 5 miles round trip. thanks for your guys input it has been a lot of help. i'll post some pics when its complete, and those close enough will have to come out and play lol

Might be cheaper to just drop a small block in the truck and not worry about trailers at all. Or is he giving you the tank because he found a home for the truck?
