Learn how to create simple, low-maintenance, legal, and effective household graywater harvesting systems that use gravity to direct graywater directly into the landscape (no stinky tanks) where it passively irrigates landscape plantings. This can greatly lower water consumption and water bills, while enhancing and beautifying your yard. A presentation will kick off the tour discussing how to create graywater systems, graywater-harvesting guidelines, materials and suppliers, graywater-appropriate soaps and detergents, marrying graywater- and rainwater-harvesting earthworks, and how to maximize your graywater-irrigated landscape’s potential with passive solar design, food production, and oasis design. We will also discuss tax credits for rainwater- and graywater-harvesting systems. After this presentation we will tour four residential sites in central Tucson, all within walking, bicycling, or driving distance of one another. On this tour we will see graywater used with indoor and outdoor showers, baths, and sinks, washing machines and communal laundromats, and 3-way diversion valves and/or multi-drain options allowing graywater distribution to the landscape or the sewer. Note: all graywater systems toured will be graywater systems installed/retrofitted within existing construction. Instructor: Brad Lancaster, author of Rainwater Harvesting for Drylands
