This succinct handbook addresses everything the homeowner needs to know to plan and install a greywater system. Readers will learn how to identify greywater sources in their home, estimate the flow rate, and plan what areas of their landscape and which plants to redirect the water to for the most effective system. Step-by-step instructions are provided for installing a laundry-to-landscape (L2L) system, a branched drain gravity-fed system, and a greywater system with tank and pump, including the basic plumbing knowledge required to install and maintain each system. AUTHOR: Laura Allen is the author of ‘The Water-Wise Home’ and cofounder of Greywater Action, a collaborative of educators who teach residents and tradespeople about affordable and simple household water systems that dramatically reduce water use and foster sustainable cultures of water. She leads classes and workshops, including the first training program for professional greywater installers, and participates in writing state government greywater and composting toilet codes.
SELLING POINTS: . Water shortages and drought conditions are forcing mandatory reductions on outdoor watering. Currently in the midst of the worst drought in modern history, Californians are struggling to meet the mandatory statewide water reduction limits (25 percent), including restrictions on watering of outdoor plants, gardens, and lawns. . Graywater systems offer the opportunity for major savings. A greywater system that redirects the wastewater from washing machines, showers, bathtubs, and sinks to the landscape instead of the sewer can save up to 2,775 gallons a year in a single household. Wastewater recycling is predicted to explode in the coming years, with cities such as San Diego pledging that one-third of city water will come from reuse by 2035 (Newsweek, 2015). . Accessible, low-tech systems. Step-by-step installation plans for redirecting water from the laundry room and bath into the landscape are accessible to the average DIY homeowner with a set of basic tools and materials that are available in home supply centers.
