California, Oregon and Washington are among the states moving forward with regulations and road maps for the construction and operation of building- and district-scale graywater capture and treatment systems for non-potable-water use, such as toilet flushing and irrigation.
The 645-foot Millennium Tower—the tallest reinforced concrete structure in the Western United States—is sinking and tilting, and the building owner places the blame squarely on the adjacent Transbay Transit Center project.
Earlier this month, the first building in the U.S. permitted to treat rainwater for potable uses also became a Living Building—the highest level of ultra-green-building certification granted by the International Living Future Institute.
