“”Chlorine tablets?””
I’ve read that a drop of bleach in water gathered will make it safe for drinking and pool water may be safe? I’ve stored water and probably should recycle it on plants and add a drop of bleach in each bottle as I refill...I dated the bottles and almost afraid to check to see how old those are now...
Those things work, but rainwater is about as pure as it gets. Just stick a pot outside here in Houston, and you get all the distilled water you could want for free ;-)
