Water and Water Bottles

Every parent knows the frustration of having their child cry at you because the park's drinking fountain isn't working and you didn't bring water with you... or maybe that is just an Arizona problem for Arizona parents. But I'm pretty sure it is mostly a first world problem we can all relate to.
I hate standing at my water filter filling water bottle after water bottle- one for each child and one for myself. Takes forever. We have an in fridge water family size water pitcher. I know there are those of you out there thinking 'suck it up and use tap water'. This is true, it would save me tons of time and probably the money from buying the water filters. But the thing is we are on a well and our well water isn't filtered. It doesn't bother me to bathe in it or wash my clothes in it, but I have issues with drinking it. It may be fine, or it may not be. We have never had it tested. So until then I prefer to drink water I filtered.
We all have (or maybe its you) that friend who every time you turn around has bought a new bottle of water from some store. Last summer I started buying a gallons of water at the grocery store. Then I had the idea of re-filling the gallon jugs at the water kiosks. Now in Arizona they are everywhere. I don't know if it was just where I was but when we went to California on vacation I couldn't find them anywhere. For those of you who don't know what they are, they offer 1 gallon fill ups at a time for 25 cents or 5 gallons for $1. Lots of people use them to refill their freestanding water coolers. Yes that is 25 cents every time I refill it. But I use random change, and when I can remember I will refill the gallon jug from my filter at home. Some Kiosks even have chilled water. Those are my favorite.  I refill our gallon jug at least once a week during the hottest part of the summer. I bring it with us to the park (which is at least once a week, often twice or more). I keep a few cups or water bottles in the car and we fill them up from the gallon jug. When all is said and done it is only about $1 a month if I don't fill it at home at all. Yes its not freezing cold water. But it is water and most of the time it is just room temperature. The important part is that it is making my life easier and is a lot cheaper then buying new every time you are out and about.
