Abstract

Embodiments of the present invention provide methods and apparatus for water conservation with landscape irrigation controllers, plug-in and add-on devices, and centralized systems. In embodiments of the invention, a water budget percentage is determined by comparing current local geo-environmental data with stored local geo-environmental data, and the preliminary irrigation schedule or station run times are automatically modified based upon that water budget percentage. Embodiments of the present invention also provide for automation of mandated landscape watering restrictions alone, or in various combinations with water budgeting methods and apparatus.
