Graywater Systems for Your Garden
This is a great talk by Laura Allen (here walking us through her home humanure system) and Gregory Bullock about setting up a home graywater system.
“Greywater (water that comes from sinks, showers, and washing machines) turns wasterwater and its nutrients into irrigation water, saving time, money, and fresh drinking water. Whats more plants love it, especially fruit trees, berries and vines. Last year California rewrote its greywater code, making simple greywater reuse legal and affordable. Learn the why and hows of greywater reuse, and how to transform your household plumbing into a greywater irrigation system.”
They are in California so some of the impacts, positive and negative, that they talk about here focus on that state, but the issues are similar everywhere.
The talk covers really important Dos and Don’ts. Some topics mulch and mulch basins as filters, choosing good soaps and cleaners to use in your home if you are going to set up a graywater system, how to set up plumbing for the system (they look at a system that uses the pump on the washing machine as its driver), costs, types of crops it is suitable to irrigate (apparently root crops are out but it’s fine for “fruit” and leaf crops.
