Cistern under my house - bad idea?

Here in northern California we get essentially all our rain in the winter and none in summer. If I were ever to have the funds to build a home I'd like to make it water efficient. My idea is to have a grey-water cistern under the house or under the yard and an elevated water tank. A windmill would pump water from the cistern into the tank. The tank would supply water for flushing toilets, watering the yard, washing the car. Water from the kitchen and toilet would flow to the sewer as usual, but water from the bathroom sinks, showers, and washing machine and rain from the roof gutters would go into the cistern.

Please shoot me down and tell me why this is a really bad idea.
