The OP's question has gone off topic in regards to what you have done to save water in this drought situation.
Everyone, including me, has posted everything but.
Here's what my neighbors have done to the front of their property, when the houses changed ownership.
No more front green lawns, and a desert landscape type of scenery was put in.
Getting to be more common in my area, doing away with grass, that doesn't have to be watered.
