Back-up water supply if mains failed

Yorky

In the event of a disruption to the mains water supply, how can stored rainwater be purified to drinking-water standards without chemicals?

Reckon I'll stick with boiling the water and leaving it cool

Me too. Just seems a bit 'meh' to me.

It claims to get rid of faecal coliforms, by filtering it to 0.01 microns. The test to check for coliforms is carried out on 0.45 micron papers and requires a vacuum pump to draw the water through it.

Hence the reason it is designed as a straw, you need to suck like a f****r to get the water, whcih probably defeats the purpose of getting it in the first place.

As mentioned already, boil the water, let it cool, there is no better solution.
