There's a spigot on the side of the building. We asked if we could use it and they said "sure if it even works". It did🙂 We used our hose with inline RV filter. We drank it for a few days and we're fine. Went back another day and just filled up without asking. Need a square key to turn on. They’re closed on Sunday also but the spigot is accessible.

You need a key to use this spigot and they wouldn’t let us use it, don’t count on this for water
