A small wet bath provides a place for the couple to wash up. Tammy says, "Right now I don't use it because I shower after my yoga class, and Logan showers at his office."Graywater from the kitchen sink and wet bath flows together into a single pipe, then collects in a five-gallon container under the house. Tammy explains, "We use the graywater to irrigate ornamental trees and shrubbery. So far, we have been producing about 1.5 gallons of graywater a day or less." Black water isn’t an issue for the couple because they have a composting toilet, following the Humanure Handbook.
