I always like to keep some drinking water in the car Boot. I have it stored it in a metal flask.
Thinking it was in the dark i assumed it would keep almost indefinitely and i guess it could have been kept in there for a year.
Someone has just pointed out to me that Mould grows in airless and dark environments. But it still looks alright ?
What is the best way to store tap water ?

Swap the water out every 2 months or so - more often in summer.
Tapwater isn't sterile so whatever goes into the container stays there
and multiplies. It always amazed me that biofilms would form inside the
vessels containing the purest distilled water we can make. NASA finds it
something of an inconvenience for water recycling in space too.

There isn't ... unless you include ice cubes

Buy a can of water every few months and replace it. You can buy canned
water in Tesco.

Bottled water may keep, check the dates on the bottles.

Run the tap for at least a minute before filling your container. That
should ensure that you get mains drinking water and not water that has
been standing in your pipes, breeding bacteria. Drop a couple of water
sterilising tablets in before sealing the container. Change the water
every few months.

If you're really concerned, boil a kettle of water. When it's boiling,
flush out the metal flask with some of it. Then fill the flask with more
boiling water and seal. Leave to cool. Whether it will still taste the
same - or not - as fresh cold tap water I can't say.

Or just buy a bottle of water from a shop. I don’t normally approve of
bottled water but if you’re keeping a supply for emergencies in your boot,
pre-bottled water will keep much longer. A lot depends on just how long
you might it expect to be festering in your boot for.

Why should it last any longer than water prepared the way I suggest?

If you use water purification tablets, it shouldn't fester at all.

First get your purification tablets. Right, I’m sure I have some here
somewhere… Nope, off to town to an outside door shop to buy something I’m
gonna use once in a blue moon, OR, I buy a bottle of water from just about
anywhere.

Seriously, not worth the hassle.

Amazon is simpler.

I find them quite useful to have around. Then again, I drink a lot of
tap water with added CO2 and the pressure bottles need occasional
sterilisation to avoid becoming musty.

You obviously lack the prepper gene.

Keep two cylinders of Hydrogen and Oxygen and make your
own on demand.

I'm not in the UK right now and out here we have similar issues caused
by an unreliable electricity supply which often causes the water
supply to shut down.

Our routine is to keep several bottles of fresh tap water on the
premises, use the oldest to water the houseplants then refill the
bottle and put it at the back of the queue. Rinse and repeat.

Maybe you could do something similar? Use the bottled water from the
car whenever you want to wash the lights, plates and windscreen then
put a fresh bottle back into the boot afterwards?

My Brita filter unit say to use the water within 48 hours. Does
unfiltered water last longer?

Filtered water practically guarantees there will be photosynthetic algae
and bacteria in it (especially if the jug is in sunlight). Water from
the tap once it has run for a short while is fairly clean. It goes
downhill from the moment that you put it in a non-sterile bottle.

I keep four bottles in a cooler box obtained from Halfords a few years
ago, permanently connected to a cigar lighter socket so it's chilled
whenever I go out.

What happens when you are not using the car and it is 35C outside
though ?. How often do you empty and refill those bottles with
fresh water ?.

I don't have it there for emergencys, I have it there for drinking
when not at home.

I am happy to lose it. Just tried to get some blank DVDs locally

Never had much luck with the cheapest DVD blanks

The OP did not mention where the car was kept. When I was in the UAE I
used to keep am bottle of water bought from a shop, in the boot for
emergency use. Fortunately I never had to use it.
