My personal motto has always been “plan, don’t panic”. And something as simple as putting a few jars of water in the canner can help you plan for extended power outages, emergencies, or when you might need access to sanitized water.

This is one of the simplest canning projects you can do, making it perfect for beginners. Even better, it’s something that can be accomplished slowly.

Let’s say you’re Canning a batch of peaches and you don’t have enough jars to fill the canner. Pop in a few jars of canned water and congrats, you just took one easy little step toward caring for yourself and family.

How Do You Can Your Own Water?

It’s incredibly simple! You take clean water and boil it for 10 minutes and then water bath can it for 20 minutes. Allow the jars to seal and store in a cool dark place. See the printable recipe card at the bottom of the post for additional details.

Pro Tips

  • Water in the canner must cover the jars by 1-inch the entire time they are processing. Half-gallon jars are most convenient for storage, but you must use a canner that can accommodate their size.
  • You cannot reuse lids from jars of canned water for other canning projects. Save them for freezing jars of water or soup, or even for affordable dry goods storage (related: Pantry Essentials).
  • You can technically store the water indefinitely, but to be honest, I would probably replace jars every 2-3 years.

Canning Water is great for emergency preparedness or power outages.


  • 7 quarts water {+ more for the canner}



  • Wash and clean your jars. Set aside.
  • Wash your lids with hot soapy water and place them in a clean bowl for now.
  • Prepare your water bath canner by filling it with water. You just need to have enough water to cover the jars by 1 inch once the water is boiling.
  • Fill a clean stockpot with 8 quarts of water and bring to a rolling boil for 10 minutes.
  • Fit jars with a canning funnel, and using a glass measuring cup with a handle, carefully pour water into the jars. Leave 1/2 inch headspace.
  • Wipe the rim of the jar with a dry rag.
  • Place a clean new lid on the jar. Add a ring, and tighten to fingertip tight.
  • Using canning tongs, gently place the jars in the canner.
  • Put the lid on, and set your timer. Pints, quarts, and half-gallons should process for 20 minutes. Pro tip: the water must return to a boil in the canner before you can start the timer.
  • Once the jars have processed, remove the canner from the burner, carefully take off the lid, and allow it to sit for 5-10 minutes. Pro tip: I tend to just slide it into the middle of my stove, as it weighs a ton.
  • Carefully remove the jars, and place them on a thick towel in a place where they can be undisturbed for 12 hours. The lids should start to pop within 20-30 minutes of being removed from the canner.


Step 4 has you boiling 8 quarts of water, but you'll only be canning 7 quart jars. The extra water is to account for any water loss during the boiling process.
You can technically store the water indefinitely, but to be honest, I would probably replace jars every 2-3 years.

  1. We have clean jars that we are sterilizing in canner. My question is, since we are bringing this water to a boil can we skip using another pot to boil water to can by just using the water we are using to sterilize the jars in as the water we can?

    • I would say as long as the jars you’re putting in that water to sterilize are already clean, and nothing else is going in that water, then it should be ok.

  2. Hi I want to do my water in half gallon jars I have but my water canner or pressure canner are not y’all enough for me to have the water over the lids as needed. If I use a pot with a lid that gives me the space I need, does it need to have a rack of some sort for the jars to sit on or can they sit directly on the pot? 

    • You need a rack on the bottom to keep the jars from cracking. If you don’t have a rack that fits in the pot, a super easy “DIY canning rack” is to zip tie a few canning rings together and place the jars on top of that.
