Storing pure water... how long?

Recommended Posts

Dundeeladdie

Hi all. I'm new to the forum and am thinking seriously about starting a window cleaning round up. Read loads of informative and inspiring threads on here, so thanks all of you.

My question is... Once the water has been purified and put into 25ltr containers does it stay pure indefinitely or is there a 'shelf life?

Thanks.

Just checked a 25ltr clear container that had 000 ppm put in it about 3 years ago left out in the garden in all weathers.

 

The tds reading I have just taken is showing 007 ppm but no way would I want to drink it :D

The RO filtration process takes out chlorine, minerals etc but doesn’t take out micro organisms out of the water. So if they are given sunlight and warmth will multiply quite happily. So you can end up with a microbiological soup with wiggly things in it and all :D

so you cant beat nature.....it makes you think.....thats why they look for water first across the universe for life...:)

 

i reckon two weeks at the most...if covered maybe longer...but why would you want to store it any longer? i suppose if its holiday time...i remember them...once upon a time....:D

My containers are so old now I tried moving them and the handles snapped off so just goes to show plastic doesn't last forever either.

Not as annoying as if you drop a full one on your foot when that happens. Lucky for me i didn't but the container did shatter rather well when it hit the ground though. :D

I also had some lying around for a year or so, but although the TDS is still low, the inside of the container is green with algae.

We used to get through 1400 litres a day on commercial work 5 days a week once a year we did have to scrub the inside of the water holders as over the year they turned green with algae never affected tds but very weird how it grew :-0
