Hi Sheila,
Glad to hear you being creative and saving. You'll be amazed at how much you can conserve and reuse.
I've been practicing water conservation for ages. I lived in Sacramento in the '70s when we had a 6 year drought. Bricks in the toilet tank/reservoir, flush only when necessary, no lawn watering running into the street (one could be fined).
I have a self imposed policy here in Phoenix that I must use all faucet/tap water at least twice (unless I'm drinking it). I even save the ice cubes that get stuck in the ice maker. Water to boil artichokes, corn (as you point out) is saved and used to water outdoor plants. I have a watering can in the shower to catch the cold water that runs before the hot. (though in PHX we don't have cold water in summer.) I use second or third round water to rinse dirty dishes prior to putting them in the dishwasher. When water bowl for dog is refreshed daily I use the unused to water plants.
Thanks for joining the crusade!
