Why Focus on Landscape Water Use? Outdoor 53% Indoor 47% Source: 2011 California Single Family Water Use Efficiency Study 6

Moderately-Efficient I rrigation System Overhead irrigation that uses slower precipitation rate so water has a chance to absorb into soil with little runoff  Rotating nozzles  Stream rotors 7

Highly-Efficient I rrigation System  A drip system is the most efficient type of sprinkler  Water is applied directly to soil  Zero overspray and very little runoff 8

Highly-Efficient I rrigation System  Bubblers  Ideal for shrub plantings, trees, containers and flower beds. 9

Trees - I rrigating Your Garden’s Bones  Benefits  Shade reduces the air temperature by up to 15°  Drivers slow down on tree-lined streets  Can increase home prices up to 9%  Irrigation  Priority during a drought  Water less frequently, but for longer periods  Give your trees their own irrigation zone  Water at the dripline 10
