Graywater definition includesKitchen sink wastewater
MissionThe Oregon Legislature directed the Environmental Quality Commission to consider the recommendations of a newly formed graywater advisory committee when adopting new rules, as well as to:
• Minimize the burden of permit requirements on property owners;
• Prescribe requirements that allow for the treatment, disposal or reuse of graywater; and
• Ensure the protection of public health, safety and welfare; public water supplies; and state waters.
Rules and Regulations
• DEQ regulates the use of graywater outside a building structure in Oregon. How graywater use will be permitted and allowed under the new law will be defined in the new graywater rules.
• Non-potable use of graywater within a structure is regulated under the state plumbing code.

How Much Graywater?
Data from Water Environment Research Foundation (2007)
How Much Graywater?“The buildings also recycle all of their "gray" water by filtering used water from sinks and bathtubs and reusing it to flush toilets, irrigate roof gardens and fill the structure's outdoor ponds. This reduces water use by more than 40 percent.” (China Daily, 12/30/2009)
