a~ AUTOMATIC CONTROLLER. A mechanical or electronic device capable of operating an irrigation system and its component valve stations according to a pre- determined schedule of irrigation frequency and duration. CISTERN. A tank or container, typically located underground, for the storage and subsequent reuse of rainwater collected from rooftops or other impervious surfaces that would have otherwise evaporated or drained off the premises. DRIP IRRIGATION. The application of irrigation water through drip emitter devices at low pressure, volume, and velocity near or at ground level in order to minimize runoff and evaporative losses. Drip irrigation emitters are typically used for irrigating non- turf vegetation and release water in the range of 0.04 to 0.40 gallons per minute. EVEN-NUMBERED PROPERTIES. Properties with street addresses that end in even- numbered digits, or other properties so designated for the purposes of these Standards through special arrangements with OWASA. GRAYWATER. Domestic wastewater collected from household fixtures and appliances, such as washing machines, dishwashers, showers, sinks, and bathtubs, but not from toilets or urinals. Grawater may only be reused in accordance with practices approved by public health authorities. HAND WATERING. The application of water for irrigation purposes through a hand- held hose or watering container. HARVESTED WATER. Precipitation or irrigation runoff collected, stored and available for reuse for irrigation purposes. IRRIGATION SYSTEM. Any permanently installed system of pipes, hoses, or other conveyance devices and appurtenances that provides water to living plant material through spray heads or other emission devices located at, above, or below the ground surface. For the purposes of these Standards, a sprinkler, soaker hose, or other device connected to its water source via a moveable above-ground garden hose is not considered to be an irrigation system. LANDSCAPE AREA. That portion of a parcel that contains turf or non-turf vegetation. LOW-PRECIPITATION BUBBLER. An irrigation head which typically operates within six inches of ground level and delivers water at a rate of less than 0.45 gallons per minute within a radius of less than two feet of the head. Low-precipitation bubblers are typically used for irrigating non-turf vegetation. MICRO SPRAY. The application of irrigation water through small, low volume sprayer heads in order to minimize runoff losses. Micro sprays are typically used for 2
