Erik Knutzen talks about utilizing greywater at Altadena Heritage’s “Heritage of Abundance” talk Wednesday night at the Community Center.  Knutzen, author of The Urban Homestead, explained how to establish a greywater system using washing machine discharge on fruit trees and ornamental plants.  Such a system can be set up for under $100 (including a $45 valve), but there are a lot of conditions and caveats in the process.  Still, setting up a basic greywater system is easier than you’d think.
