Scientists are hard at work trying to develop plants that are genetically engineered to require little water to grow, but we can also do our part. One way is through a gray water rerouting system.Now besides this, you will also have to look into water and electricity connections as well as telephony lines. See how long it will take you to get these up and working.

It also eliminates the heat losses inevitable with long runs of pipe.
