I had a great email from one of our readers, Bill Roth, who has developed a set of 4 homes out in San Antonio called Arroyo San Antonio. He incorporated a lot of common sense features attentive to both power and water conservation: energy star appliances, dual flush toilets, front load washing machines. I was particularly struck by his approach to greywater harvesting. Obviously being in the desert the good residents of San Antonio are very water conscious, but frankly we all need to think that way. Too much water flows through our homes that can be given a second use, and we all need to think about water consumption more seriously.
