It should be something similar to this : https://www.gcfdn.org/Giving/Funds-of-the-Foundation/Procter-Gamble-Charitable-Giving/Childrens-Safe-Drinking-Water-Fund
A human can go for more than three weeks without food, but the maximum time a person can go without water seems to be a week.
We saw what massive difference the Pineapple fund made to charities, but I think a project like this will make an even bigger impact, because the water sources for many people are filthy around the world and a few packets like this will provide clean drinking water for 1000's of people for a whole year.
Do you have any interesting projects that can be linked to donations for charity projects like this? Please find a way to include this in your projects or to start something new.
We can also crowd ask that P&G fund to accept donations in Bitcoin to also boost that project, if we cannot start something on our own.
They currently only accept Credit card payments. 
- $7.50 - give a child clean water for a year...
