Old Fashioned Water Saving Methods

When I was a young kid my grandfather used to talk about the rainwater tanks all the time.  He seemed to always be checking them when it had just rained.  I didn’t know much about them, only that they were very important to him and seemed to take up a lot of his time.  The older I got the more I learned about their uses and the importance of having them around.  I now have 4 of them on the back of my house and could not imagine those hot months without them.  Watering plants is so much cheaper now.
