Estimate how much graywater your clothes washer produces

The amount of graywater your clothes washer will produce depends on two factors:

  1. Your laundry habits, and
     
  2. The age and type of your clothes washer. A newer, high-efficiency front-loader clothes washer may use less than 15 gallons per cycle compared to an older, conventional top-loader, which may use 45 gallons per cycle. That’s three-times the amount of graywater! 

Estimate how much graywater you may produce in a week to get a sense of how much of your landscape can be irrigated with the graywater.

Weekly Graywater Produced = Loads per Week x Gallons per Load
