Systems of water sanitation, unless you want to count cholera and dysentery as losers.

Arguably those don't create winners, because the concept of "win" necessitates triumphing over others.

Yeah I don't know anybody personally who feels like a winner because they have clean drinking water. It's universal where I live. In places where it's not, you might feel like a winner when the neighboring village doesn't have it, and sucks to be them.
