If you're talking about Haiti, most small towns in the Caribbean collect rainwater for drinking water - each home collects runoff into a cistern, and they use that. The cistern costs some money up front to build but the water is free after that. Even on fairly large and wealthy islands (St. Martin, for example) have limited distribution of piped water.
They buy water (made from seawater via RO) only when the cistern runs dry (probably not even then in Haiti). Only the core part of PAP have actual running water, and IIRC the sewage goes into cesspools that are pumped out, and then hauled to a waste treatment (kind of) facility. Small towns just have septic tanks.

I make the ADL soil themselves. And that makes me very happy
