Melaver Residence: Water Conservation
Steps to help relieve the high consumption of water have lead the Melaver team in the direction of recycling the gray water from the homes washing machine and sinks. The water will be re-purposed to flush the toilets. 
The system designed and installed by RainHarvest Company of Atlanta, GA will provide two underground tanks one for gray water and the other for rain water storage that will be used to irrigate the back garden.

Study: Toilets Need Radical Redesign

The Western World's dependence on flush toilets could be its environmental downfall.
Toilets that use less water, such as the "squat toilet" in which one squats over a hole in the ground, are prevalent in parts of Asia, Europe and Africa, but a new historical study suggests that after decades of flushing, it will take radical innovations for the mainstream West to adopt any new system.
"Most people can hardly imagine that other ways of handling human waste have ever existed," said study author Maj-Britt Quitzau, an environmental sociologist with the National Environmental Research Institute of Denmark. "But actually, systems did exist prior to the flushing toilet where human waste was collected within the cities and re-used in farming areas."
Since the 1900s, scientists have known that flushing away human waste comes with environmental consequences , such as using precious, potable water. Each year, a typical person will use almost 4,000 gallons of drinking water to flush away 75 pounds of feces and 130 gallons of urine, according to a 2001 study by the Swedish International Development Cooperation Agency.
While drinking-water shortages plague millions in such places as India and in some African nations, Westerners continue to oppose alternatives to the flushing toilet.
