It’s official: California is once again in the throes of a drought — our worst in about 100 years. We’re being asked to cut water use. Here’s a simple water-saving tip, no matter what state you live in.

We’ve all been guilty of running water into the kitchen sink as we wait for it to warm up (or cool down, depending on Southern California’s season). Next time you finish the contents of a plastic juice or milk jug — preferably a gallon, but two half-gallons will work too — wash it out thoroughly and then sit it by the sink. (Wash and save the lid, too.) Next time you need hot water, run the water into the jug first. I find that after I fill a gallon jug, the water is warm enough (or cool enough) for me.

Cap the jug and use the contents for other things: Fill your coffeemaker or teapot. Fill the pasta or soup pot. Water plants. Replenish your pet’s water dish. I’m sure you’ll come up with more ideas.  That’s a gallon of water saved, and money in my pocket.

I also stash half-gallon jugs of water in my bathroom cabinets for possible emergency use. (That’s about the only emergency supplies I have, but at least it’s something.) I write a date on them with an indelible marker, and then rotate the jugs every few months. I usually use the water on plants, then refill the jugs, redate them, and re-stash them. Save water, save money, and be a little bit more prepared!
