The Regulatory Reality Lawn care accounts for more than half of outdoor urban water use Outdoor landscape irrigation - 50% Efficient -Lower priority than water use for consumption, fire protection, health & safety Baths 1% Dishwashers 1%

The Appropriate Targets Runoff…Over Spray…Geysers… Low Head Drainage…High Pressure Misting

PUMP IT … PIPE IT … FILTER IT … TREAT IT Takes ENERGY Water Treatment

Water Waste Is Also Energy Waste

No Magic Bullet Design Install Maintain Manage KEYS TO IRRIGATION EFFICIENCY People Products Practices

Precision™ Irrigation  Exactly the right amount of water  Applied at the correct time  Only to the targeted area  With resource efficient results

Strategic Statements About Landscapes “The State Legislature has found that landscapes are essential to the quality of life in California by providing areas for active and passive recreation and as an enhancement to the environment by cleaning air and water, preventing erosion, offering fire protection, and replacing ecosystems lost to development.” AB1881 Model Water Efficient Landscape Ordinance Sustainable Sites Initiative “…any landscape, whether the site of a large subdivision, a shopping mall, a park, an abandoned rail yard, or a single home, holds the potential both to improve and to regenerate the natural benefits and services provided by ecosystems in their undeveloped state.
