We have started saving water in various ways to keep some for our
plants. We have a 5 gallon bucket in our kitchen for when we need hot
water to wash dishes. Our kitchen is far enough from the water heater
that it takes most of a gallon of water to get the water running hot.
Now I put the bucket under the tap when I need to bring up the hot
water, so there's always some extra for the plants.

If the drought continues for a few years, I may have to invest in a gray
watering system...
