Water waste making you insane?

The Bite
The fact is that, if you're reusing bath, kitchen, or laundry water, so consider hooking up a system that directs gently used water (called gray water) to your garden. Huge cerebrum not required.

The Benefits

*Saving H2O. Gray water systems can save up to 40% of drinkable water, and if enough people install systems, we could have smaller water-purification and sewage-treatment plants.
*Money in your bank. Hooking up a gray-water system can snag a tax rebate in some states (check with your city gov's water management department), and up your home's LEED credits to increase its value.

Personally Speaking:
One of our dads hooked up a gray water system for his garden, but we can't say whose since it isn't exactly legal without a permit in his state. How about you guys?
