SLIDE 18: Patterning
Since every site is different, every client is different, and every landscape designer is different, I like to use permaculture’s “patterning” concept to approach the teaching of what I do. Patterns found in nature are easy to learn, easy to remember, easy to apply, and they increase the water harvesting potential of the site. They also contribute to the aesthetic quality of the land—they’re beautiful! If designers understand the power of natural patterns, they can begin to design ecological, functional, land long-lasting landscapes that inspire the soul and are effective at attaining a client’s goals.

SLIDE 17: Four Ways to Harvest
In my talks, public presentations, and interviews, I almost always explain that there are four forms of water harvesting, and my lecture at the Association of Professional Landscape Designers was no different in this respect. Active water harvesting is the form that pumps water out of a water storage tank called a cistern. Passive water harvesting stores water in the soil. Wastewater harvesting recycles greywater (from clothes washing machines, bathroom sinks, showers, etc.) and blackwater (from kitchen sinks, dishwashers, and toilets). Community water harvesting deals with the use of stormwater on a community-wide scale.

Greywater Action
Greywater Action has helped thousands of people learn about and connect to greywater. It has an excellent website with easy guides to explore greywater reuse, rainwater harvesting, and composting toilets. Based in California, the group often has workshops that teach people about greywater systems, costs, codes, irrigation systems, and plant friendly soaps.

SLIDE 16: Efficiency
Here’s a better look. Even with only 80% efficiency the two surfaces have the potential to harvest close to an acre foot of water per year.

Santa Fe Honored as Desert Lab Rat
From my latest column:
At a Jan. 5 press conference announcing that Santa Fe had received a distinct national honor for its approach to stormwater management, Mayor Javier Gonzales juxtaposed 20th-century goals for urban-runoff management with the city’s current, science-based approach. By recalling how his father, George Gonzales (Santa Fe’s mayor in the late '60s and early '70s), was trained to divert stormwater as quickly as possible away from the built environment in order to protect buildings, roads, and bridges, Javier explained how he wants “to reverse that trend and slow (runoff) down as much as possible in order to create another source of wet water… and have as much water security as we possibly can.”
