You might want to pop open your phone book and look up Church of Jesus Christ of Latterday Saints. If a cannery is listed, call them. The one near me has a full, assembly-line cannery but it also has small units one person can operate to fill #10 cans he buys from them (and no, they don't gouge prices). Ask if they'll let you can water.

If no cannery is listed, call the ward closest to you on Sunday. If you don't get an answer, keep calling about once an hour. Ask for the number of the ward canning specialist. If they don't have one, ask for the Relief Society president. That person would be able to help you.

Good luck,
