Water Bob is a good place to start for water peace of mind.
Based on what you've said in this thread, it seems like your most reasonable preps will be for bad weather. Do you have a small shovel and bag of salt in your vehicle for winter? How about an extra pair of gloves and a hat just for the car, or an emergency food stash if you get stranded somewhere? Flashlights are always a good, cheap thing to have on hand as well.
WaterBobs are a great purchase in my opinion. 100 gallon bathtub insert to keep water clean and fresh during an emergency for only $34.95. We have one for each bathtub.

Buy a WaterBoB instead.
Thank you for sharing. Just a few more things to add. These are a few things that I purchased... and yes, I've linked everything in case someone wants to check them out.
Ummm... I think that's it.
Edit: Even if you don't use these this winter, there's ALWAYS the storm season and hurricane season. Most of the items above can be used for ANY emergency.
Something like this.
If you're worried about your bathtub not being very clean or if it has leaks, there are bladders you can buy. Even has a hand pump.
