Water kiosks usually sell fresh water for 20c-50c/gallon. The way the stations are set up may require the use of a bucket or other tall container to collect the vended water. Some search terms that may pay off: "water kiosk near me", "water vending near me", "ice vending near me", or "water fill near me".
Water kiosks are a great way to source water if free options are not available.
