What is grey water?

Water your would not like to drink. (shower water, dishwater, toothbrushing water)
(Black water is what goes down a toilet)

How can I minimize the creation grey water?

• Take less water to the playa: you will conserve water if you bring less! However 1.5 gallons per person per day is the bare minimum. You don’t want to have to ration your drinking water in the desert.
• When you shower, get wet, turn the water off, soap up (scrub those nooks and crannies), then turn the water back on to rinse off
• Shower with a friend: a friend can efficiently rinse the soap off as well as wash your back
• Use a pump-up pressurized water sprayer for dish washing http://www.nextag.com/pump-sprayer/search-html
• Minimize the creation of dirty dishes: eat right out of the pan! Share utensils!
• Lick your dishes clean! Then swirl with clean water to remove any food bits –> next, drink that water! YUM!
• Wipe out dirty dishes with paper towels/wet wipes or use paper dishes: burn the paper in one of the burn barrels

What are the rules about disposal of grey water on the playa?

[This is a recollection, and needs verification]

BLM’s list of stipulations for Burning Man forbids disposing of untreated graywater on the playa. What constitutes treatment is not specified, but would probably be satisfied by filtering out solid matter and disinfecting with Clorox. An amount of water sufficient to create a muddy patch is of concern; smaller amounts aren’t. Playa visitors not attending Burning Man aren’t bound by stipulations, and should be guided by common-sense wilderness ethics.
