News -06-16-08 Gray Water (OasisDesign.net) "Any water that has been used in the home, except water from toilets, is called grey water. Dish, shower, sink, and laundry water comprise 50-80% of residential "waste" water. This may be reused for other purposes, especially landscape irrigation." "It's a waste to irrigate with great quantities of drinking water when plants thrive on used water containing small bits of compost. Unlike a lot of ecological stopgap measures, grey water reuse is a part of the fundamental solution to many ecological problems and will probably remain essentially unchanged in the distant future." Also called grey water, graywater, or greywater. 06-08 -06-16-08 Gray Water Recycling Supported in Two States (KPTV.com) "Oregon's State plumbing board meets this month to discuss rules permitting reuse of "gray water" inside homes to avoid having to flush drinking water down the toilet." "Only Arizona and New Mexico have standards for such gray water reuse." Also called grey water, graywater, or greywater. 06-08 Papers Using Reclaimed Water for Municipal Water Supply (USWaterNews.com) "When considering reclaimed wastewater for public water supplies, the public distinguishes between direct and indirect use. Adding highly treated wastewater directly into a water supply without storing it first in a reservoir is not a viable option. Indirect use is viable, however, and that approach was examined by the committee. Indirect use augments the drinking water supply by adding reclaimed treated water first to a lake, reservoir, or underground aquifer. The mixture of natural and reclaimed water is then subjected to normal water treatment before it is distributed as drinking water for the community. Since the 1960s, California's Los Angeles county has operated an indirect-use system in which wastewater, mixed with stormwater and river waters, supplies about 16 percent of total flow into groundwater basins. This mixture then is used as a source for drinking water supplies." 03-08
