Home made water tanks - 50 litre

edited September 2017 in DIY / How To Guide's
Hi guys, This arvo I started my water tank manufacture / install.
I am making up 2 x water tanks out of 90mm storm water pipe and fittings.
The front tank holds 20 litres and the rear tank should be good for 30 litres (yet to be made).
Front tank is to be located on the LHS of the transmission (same side as fuel tank). The rear tank is between the spare wheel and rear diff (at height above the spare wheel).
The rear tank will gravity feed to the front tank. Rear tank will have a filler located in the rear of my tray.
I'm going to get a 12 volt inline pump and set up a hose arrangement in the rear of my tray.
This is all at a very early stage. I have made the front tank today (about 2.5 hours work) and will attack the rear tank tomorrow. Still need to sort out supporting brackets, but shouldn't be much of an issue.
Cost for all the PVC material and HD reinforced poly hose was around $100.00

Will keep updating as I progress...

    Great idea Rokmeister. I will be watching with interest.

    I did something similar using 90mm DWV PVC pipe years ago but on a tray back. I did it as a temporary solution for a trip but 7 years later it was still going strong when I sold the vehicle (just recently). I used two pipes running east west; one forward and one aft (of the tray). I didn't join them as I figured that if one got busted up as I was remote driving, then I wouldn't loose all my water. I bolted them up to the chassis by using common commercial pipe hangers, but only using one half which I bolted to a 4"x2" pine section that I jigged sawed to match the pipe diameter. The pine was then bolted to the chassis. We thought it was important not to have any heavy items attached to the PVC, so we mounted the taps on flexible hose with common high pressure PVC fittings glued to the DWV pipe.

    Hi Ben, are you sure your pipe was not 100mm DWV?

    DWV pipe (drain,waste, vent) doesn't come in 90mm size, (40, 50, 65, 80, 100, 150mm etc.) only storm water pipe.

    Judging by the fittings, he's used 90mm storm water ;)

    Ha. Not only did I get the fittings wrong, but I also got the size wrong! I found another photo that shows the the fittings are 150mm. Even more capacity:)

    Got the rear tank made up today. Smaller capacity than I estimated (holds 22 litres). I will get 45 litres from the system once fully piped up which I'm happy with for what it cost me.
    I could have made it a big bigger but was then going to be close to the shocks. I am looking to upgrade these later and am trying to leave the water tank in place if possible.

    Hi all

    Great idea, i too had done this on a previous 4WD i owned.
    But it was going to be my last resort.

    I have been trying to find a tank on Ebay and related websites, to try and find a pre-made plastic tank to fit in rear space above the spare wheel.

    Has anyone else had any luck with such a tank???

    Try Boab. They already make a 40l fuel tank to fit there. Perhaps they can make a food grade version?

    I've been eyeing that tank off for a while now.... Fine when the kids are small, but impractical when they grow up...

    Depends of how much water you use :)
    My system holds 45 litres, perfect for hand washing or dishes on a trip.

    How do you get the water out, do you need to siphon it from both halves out of each passenger door into a cup?

    Take care of your water tanks and avoid a lot of grief. After all,could you imagine getting a dose of the squirts on day two of a trip up bush somewhere?

    If you are intending on using the water tank for drinking water, a couple of quick things that need to be done.
    1. Flush the water tank with town water (It has been treated and sanitised)
    2. After refilling the tank, add some chlorine to achieve 1.5 ppm, or another suitable disinfectant. This may be swimming pool chlorine, household bleach or a sterilising tablet available from camping stores.
    3. Don't drink old/stale water.

    If you are going to use liquid chlorine, I found a handy little calculator http://www.handymath.com/cgi-bin/chlorined3.cgi . Otherwise, 1 mL per 100 litres of water if using liquid swimming pool chlorine (10% chlorine) or 2 mL per 100 litres if using household bleach (5% chlorine).

    This process is standard for the green machine and works. It doesn't take much and is effective.

    When you think about it, the tanks are generally under the body where they get nicely warmed from engine heat and are guaranteed to grow most little bugs that like a temperature of 35+ degrees.

    My solution, bottled water or boiled. To be sure.. to be sure. But I am still going to install a water tank and am enjoying the thread.

    Before everyone says, how do you get the water over the hump, because I know it's coming, it has an outlet at each end.

    [MENTION=3767]Wallyspike[/MENTION] thanks for the info. Are you a water treatment specialist, I don't mean that in an insulting way I am genuinely curious if you are an expert. I have been using untreated water in my caravan tanks for years and in fact it is made worse because I am using rainwater. Two things I ensure occur are: 1. I keep lights away from the water and 2. I keep the tanks full during storage. Are there other things, bearing in mind I have never had an issue, I should be doing like adding chlorine as mentioned above? Are there more "natural" ways then adding chemicals?

    Public health and the environment are the areas I tend to specialise in for various councils and also the green machine, so water is right at the core. All too many times, I come across high risk practices and failures in the basics. It is not pretty.

    As far as keeping light away from water storages, that's good for stopping algae growth but it won't stop bacteria. The best way to store a water tank is dry - that is, if it can be properly dried out. (I can't with my van.) The closest solutions to treat water that meet the "natural" processes rather than chemicals are probably boiling, ultra violet light (kills the bugs, expensive) and ultra filtration. I've come across some of the ultra filtration units suitable for camping and bushwalking. The disadvantage of all these compared to 'chemical' treatment is there is no residual. That is, if the water is contaminated again, the bugs have nothing to stop them growing. Chemicals stay in the water for a few days/week or two.

    There are probably a couple of forum supporters that have camping/off road shops. they may be able to post some of their solutions. Also, it is worth doing a google search on camping water purifiers.

    I know the spiel is a bit long, but the solutions are pretty easy.
