Have you been to a colonia lately? They need water bottles because they build homes where there is no running water ---- a company here had some barrels clearly labeled "Toxic Waste" (but in English) stolen and later it was found they were being used in colonias to hold water.
I don't think there's a dwelling for miles around here that doesn't have running water...maybe I'm wrong, or maybe the Colonia folks are making the rounds.
