quote] Use the following guidelines when storing water: 1. Store drinking water in carefully cleaned, non-corrosive, tightly covered containers. 2. Store containers in a cool dark place. DO NOT store in direct sunlight. Polyethylene plastics (prepackaged milk and water bottles) are somewhat permeable to hydrocarbon vapors. Keep away from stored gasoline, kerosene, pesticides, or similar substances. 3. Stored tap water should be rotated every 6 months. Prepackaged bottled water should be rotated once a year. Check the pull date on the container. Be sure it didn’t sit on the store’s shelf for a year before you purchased it. Self Serve Bottled Water should be rotated once a year, as long as the water treatment process includes ozonation. 4. Rotate your stored water with the water you use on a regular basis. This practice helps insure you don’t have water stored longer than one year. Containers That Can be Used for Water Storage Food-grade plastic or glass containers are suitable for storing water. One-, three- and five-gallon water containers can be purchased from most outdoor or hardware stores. Any plastic or glass container that previously held food or beverages such as 2-liter soda bottles or water, juice, punch or milk jugs, also may be used. Stainless steel can be used to store water which has not been or will not be treated with chlorine; chlorine is corrosive to most metals. [/quote] Use the following guidelines when storing water: 1.

If you are that concerned about life of water in your containers then why not empty out after every trip you do? Unless you are going around the world in 1 hit you should be rotating your water containers on a regular basis.
If you have store water for long periods of time why not purchase a kit that will tell you what your FRC is? Lovibond are a company that provide this sort of equipment, they did at 1 point supply the Army with kit to compliment the water purifacation sets we used. As a Royal Engineer, I have provided potable water to Battlegroup sized formations in some very hostile locations. At the end of the day we still came down to the Lovibond kit to prove that we had the corect FRC in the water we supplied to the troops 110 D250 SE HT 110 USW SOLD RRE HSE Dynamic Gone, wife killed it VOLVO XC60 R Dynamic with some toys Polaris RZR 900XP SOLD Last edited by walfy on 3rd Nov 2012 10:53am.

Sorry for going all technical.
FRC = Free Residual Chlorine. We worked on 5ppm (parts per million) of FRC. But this will leave a slight chlorine taste to the water. Once we issued the water with 5ppm we then issued detaster tablets which then removed the taste. The adding of detaster tablets was the end users responsibility not the RE who provided the water. The longer we stored water the FRC would diminish as the bacteria in the water grew the FRC reduced to combat this. Hence we always tested water before issue and individual units would then momitor the FRC in any water they have stored. But in general units would only hold enough potable water for their immediate needs. They wouldn't store water for weeks on end. Plus when the Battlegroup is moving at a fast pace with the battlespace changing daily you didn't have the facility to transport huge quantities of water around with you.

Thanks for the info., some good reading.
I wouldn't say I was worried about the water as I can change the water with ease. It was more out of interest type question. I would like at some point a stainless steel water tank behind the N/S wheel arch with a pump/tape attached for both drinking and washing hands. 1999 Defender TD5 110 Regards John M0VAZ Econet Station 48 no clock |

We use this stuff for camping when we're not sure about the water quality - keeps water drinkable for 6 months:

Stainless steel water tanks in the wheel arch hold about 40 litres. Weight is low down and close to axle which are all good points. However they do not come cheap. Useful in a 90 if you are going on a long trip.
Alternatives include plastic tanks either on wheel boxes or between wheel arches. These are cheaper then stainless tanks Various water jerry cans are available, however avoid the cheaer ones as they will split if dropped when full! Another thing to consider are water bladders. Great advantage of these is that they do not take up much room when empty. Brendan |

I bet the S/S tanks don't come cheap. I was thinking around the 15 - 20L mark.
Plastic tank and bladders also have advantages. Is there a plastic tank that will fit under the wheel arch ? 1999 Defender TD5 110 Regards John M0VAZ Econet Station 48 no clock |

If you are really worried then you can buy a "Lifesaver 4000UF" which means you can treat dubious water in your own tanks or you can treat other water sources as you go - and thus not have the weight of drinking water in the truck (you must however have an emergency reserve if you're going anywhere where water of any description could be hard to find). You can treat up to 4000Litres for approx £120
To keep any water for longer I would not use the clear water containers - black plastic, stainless or plastic lined food grade jerry cans keep the sun off and remove one more source of energy for the nasties |

Depends if you're going somewhere nice and sunny - UV is our friend: http://www.sodis.ch/index_EN As I said a few posts back the Lifesaver/AquaClean stuff is an essential Tell someone you love them today because life is short.

Isn’t it a bit frightening to consider that all the water on the planet was there when the planet was formed and that we have been using this same stuff ever since?
Perhaps we are drinking dinosaur pee? Merlin  |

Some interesting observations
70% of the earths surface is covered with water. 97% of water on earth is salt water which leaves 3% as drinkable water Of that 3% 2% is locked up in the polar ice caps. So that leaves 1% of water suitable for drinking for an ever expanding human population! Amazing what you can learn from listening to the radio and then doing a quick google!
