Thanks! 

Agreed that the effectiveness well-digging probably does not generalize to other organizations or places

Their overhead is only $50k per year, so it's pretty small. And if we are thinking about the returns on an additional/marginal well, it probably doesn't make sense to include fixed costs in our calculations

QoL improvements: Not having to walk extended distance to get their water and then carry it back, being able to use more water because you don't have to carry it so far, not having to drink visually dirty water (https://www.wells4wellness.com/uploads/1/4/9/3/149316772/published/screenshot-278.png?1754683435)

As far as scaling goes, we plan to address that in our next post! They are a small organization, but it sounds like they could probably double in size (which would mean an additional $300k in "revenue" per year) without running out of good well options or organizational barriers anytime soon 

Does anyone know more about how the German university and immigration systems works? They accept anyone from any country who can get there and has a high school degree? And then how hard is it to stay in the country after graduation?

If they do accept anyone, and its easy to stay there after school, why aren't more people (who are a bit better off than the people Malengo's working with) doing this? Or maybe they are and I just haven't heard about it
