For those of you attending our Wednesday night greywater workshop at Good and for those of you who can’t, here’s a list of resources for using your washing machine as a irrigation source:
The New Create an Oasis with Greywater: Choosing, Building and Using Greywater Systemsby Art Ludwig. This is the bible of greywater. Follow Ludwig’s instructions and you can’t go wrong. Buy a copy via the link, and you’ll help support Homegrown Evolution.
Ludwig’s open source Laundry to Landscape system.
1″ polyethylene tubing–an alternative to PVC pipe.
Oasis Biocompatible detergent, the only laundry detergent we can find that’s appropriate for greywater use. It works great and, again, click through the link and we get a little support.
A selection of three way diverter valves. Note the 1″ brass model for laundry systems. Use these diverters to shift between sending your greywater outside or back to the sewer. Great if you have to do a load of diapers. We don’t have one, but we’re both cheap and kinda extreme.
A local Los Angeles source for drums, the Apex Drum Company: www.apexdrum.com. Phone number: (323) 721-8994. Located at 6226 Ferguson Drive in the picturesque city of Commerce. You can also scavange drums, but make sure they didn’t have nasty chemicals in them. See our greywater surge tank post for what kind of barrel we like to use. Note that you can also turn a surge tank into a rain barrel.
Our greywater surge tank version 1.0. We’ve since added a pantyhose filter as seen above to catch lint that can clog the tank and garden hose. It’s just some threaded ABS waste pipe fittings screwed together with used pantyhose.
A liquid fertilizer of the type that you could add to your greywater surge tank during a wash cycle to fertilize your garden. You could also get a fish emulsion or sea kelp based liquid fertilizer from your local nursery.
Oaktown’s Greywater Guerrillas, another source for inspiration.
