A crash course in changing the world.

3rd world countries often do not have adequate access to to clean water even without a catastrophic event. A homemade sand filter like this one. I am not sure how much water this produces.
I know there are a handful of organizations already implementing sand water filtration systems around the world. If we could somehow arrange to have pre-manufactured kits available for shipment around the world with instruction kits in the host countries language they could be air dropped, or sent in with team to be assembled and put into use.
The cost for making these kits is relatively low. Material and resources are readily available in nearby countries. We need to generate financial support and organize a team of responders to deal with the crisis. What do you see as the potential problems with this plan?
The water crisis globally is a Big Thing, so it's very good to see Evoke tackling it. But the story this week makes me a bit uncomfortable.
Dumping thousands of flyers into the river to warn people that it's dangerous? Even if they're biodegradable, I can't see how that wouldn't cause environmental havok.
Even weirder was the claim that it's inevitable that people will need personal water purification systems someday. To me, that's echoing the mistrust of public water systems that I see happening in North American culture - the mentality that tapwater isn't good enough, isn't safe enough. That leads to us paying private companies to bottle up "safer" water (which is usually just tapwater from another area anyway). Then we flll up our landfills (or our expensive-to-run recycling plants) with plastic water bottles that we never needed in the first place. Totally needless waste.
Also I'm not really sure why a commercial purification product is needed for a temporary problem with an existing, working water infrastructure. Just tell people to boil their water. Small-scale purification systems are a vital solution in parts of the world that do not have large-scale water infrastructure, so I'm not devaluing the research or production of those solutions, but if you only need to hold out for a week or two until the infrastructure gets repaired, it's overkill.

Are filters really needed on rain water? Water vapour is essentially distilled water and completely bacteria free until it condenses and falls into an already contaminated pool. A lot has been written about how acid rain causes respiratory problems but I can't find anything that says it's bad to drink. Sand filters won't filter out acids in any case.
