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

 by Larry Breed

Step 33: In Operation: High Winds

High wind will blow water from the drum in droplets and distribute it downwind for several feet.  This isn't always undesirable -- the BLM considers this to be an appropriate dispersal of treated water, as long as no muddy patch forms.

It may be undesirable, however, if neighbors are camping downwind or if foot traffic passes close to the evapotron (most of the scattered water lands close, and a muddy patch can form.) 

Some suggestions are: 
  • Lift the drive belt off the pulley wheel until the wind dies down.
  • Erect a low barrier on the upwind side, sheltering the drum.  Scrap plywood or cardboard is good.
  • Move the evapotron to a less congested location.
  • Keep the tray chlorinated, so the water doesn't smell funky and so it's evident that it's been treated.
