The wondrously named Water and Poop explains how SWEs are taking off but face major challenges. Water quality isn’t always the best and prices can be high. Plus, as the community raises itself, the poor can still get left behind, not able to afford the water.
SWEs can provide some amazing opportunities to get safe (not just “improved”) water to people who need it, but in the long run will this come at a cost to these very same people? As SWE popularity increases with entrepreneurs, international organizations, and private companies , we will just have to wait and see.
