Gray-B-Gon wind-powered evapotron for graywater disposal

Step 28 Playa preparations

You now have a working Gray-B-Gon evapotron, except for the plastic sheet tray liner and the bucket filter. Install those after you get to the playa.

If you have a laminated Gray-B-Gon nameplate, I hope you'll mount it on the propeller arm. It spreads the word and tells other Burners where to find this construction guide. If you don't have a nameplate, I'll mail you one.

Dismantle your Gray-B-Gon for transport in this order.  Place all small parts into a ziploc bag labeled with your or your camp's name.

• Dismount the propeller from its its angle bracket.  Don't disconnect the propeller arm from the mast.
• Remove the 8 nuts, washers, and bolts that fasten the gussets to the tray.   Don't unbolt the masts from their gussets.
• Remove the short screw in the drum axle, tilt the drum so the keeper pipe slides to the other end of the axle, and disconnect and remove the axle pieces.  Label them and the gussets with your or your camp's name.
• Store the propeller and the collapsed drum in a large, clear bag to protect the blades and the tulle from damage.

Take these with you:

• steps 28-34 of these instructions, printed and sealed in a large ziploc bag.
• solar path lights, to protect the Gray-B-Gon from nighttime wanderers and vice versa.
• five-gallon plastic bucket.
• one or more pairs of panty-hose with no holes above the knees.
• polypro twine.
• zip ties, at least 20.
• black plastic sheet, 42" x 55" or larger; a spare sheet, or duct tape for mending, is advisable.
• fresh 3-qt jug of Clorox Regular Bleach or equivalent. See Step 32 for info on chlorine bleach and how to apply it.
• fabric scrap, 14"x 14" or larger. This cushions the plastic sheet against abrasion by the filter bucket.
• tools including cordless drill with philips and drill bits, adjustable crescent wrench, and scissors.
• eight 1-1/2" plywood staples with 1/8" holes (from step 7) and eight 1" screws.

Before you head out
The 5-gallon bucket will house the panty-hose filter for incoming graywater. Drill a few 3/8" holes in the bottom. Also drill two holes on opposite sides, halfway up.  Study and practice the lark's head noose , which you'll use on the playa to fasten panty-hose to your bucket.

Depending on what's in your graywater, the panty-hose might clog up eventually. Taking a spare pair wouldn't hurt.
