Reduce, Reuse, Recycle!!
My creative husband thought of this idea about a year ago now, where we save the bath water after our kids take a bath. It's brilliant! We fill up the bath tub, scrub down the boys, let them play till their hearts content, then afterwards we scoop up the water, store them in jugs, and then reuse the water by filling up the toliet tank whenever we flush. Wow, that was a long sentence!
We save money on our water bill by not having our toliet take so long to fill up. I guess we just speed up the process. And this way we're teaching our kids how to recycle, reuse, and reduce. So I challenge you to try to save water in some way or another.
