Through different techniques that reuse water and process wastewater on site, some buildings in the city are removing themselves form the water grid.
"Plenty of "green" buildings strive to generate as much energy as they use, but Bertschi School's new science building is one of dozens nationwide taking it a step further. They're attempting to unplug from the municipal water and sewer system to collect, recycle and reuse water and wastewater on site, a concept often referred to as net zero water.
The U.S. Army has a goal for several installations to reach zero water, energy and waste use, and this week it designated Fort Riley in Kansas, Camp Rilea in Oregon and Joint Base Lewis-McChord in Washington, among others, to be net zero water. It also named other installations to strive for net zero use for energy and waste."
