Passive Water Harvesting


Passive water harvesting is the process of storing precipitation in the soil. Used in landscaping, gardening, and farming, passive water harvesting is, essentially, erosion control. The more water you store in the soil, the more roots grow, and it’s root mass—more than anything else—that holds soil in place.

Slowing down runoff and storing precipitation is the wise move for our uncertain climate future.

“Slow it. Flow it. Grow it,” is our motto, and PermaDesign works with clients to do just that. “We explore ways to slow runoff, flow it toward plants and as Downey says, “grow that same water straight up through branches and into the world as fruit.” This “fruit,” of course, can be an edible fruit or some form of metaphorical fruit, “like beauty, shade, wind protection, noise abatement, or a view screen, or even something more tangible, like firewood” Downey continues. But more than likely, the “fruit” is food for some beneficial creature capable of significantly increasing a neighborhood’s biodiversity over time.
