Sprays are primarily used in turf irrigation. With a spray radius between 3 feet and 15 feet, sprays can cover small turf areas and, with proper design, can do so efficiently despite having high precipitation rates. A variety of spray nozzles are also available that help increase efficiency and also adjust irrigation angles.
Rotors are the muscle of the irrigation world. Used for medium to large-scale turf areas, rotors have a radius ranging from 18 feet to 55 feet and can rotate from 40 degrees to 360 degrees. Rotors have precipitation rates between 0.2 to 0.8 inches per hour and require longer run times than sprays.
Drip irrigation is a type of microirrigation. Drip line works with low pressure and has a low-volume output, from half to two gallons per hour. Drip line applies water on or below the soil surface as drops and is used for watering hedges and shrubs.
Bubblers are a type of microirrigation. Bubblers work with low pressure but output more than drip line. Bubblers are usually adjustable and are useful for watering shrub beds and trees.
Micro-sprays and spray-jets are types of microirrigation. These micro-sprinklers are low-volume overhead alternatives for areas where drip line is not practical. Flow rates for these types of micro-sprinklers can range from 5 to 30 gallons per hour.
Handwatering is usually allowed during water restrictions, because it uses less water than an automatic irrigation system.
An irrigation system is only as efficient as it's maintained to be.
Even an efficient irrigation system can waste water if it's left on for too long. The ideal amount of water to apply is 1/2-3/4 inch. Figure out how long to run your system by doing a test:
Rain barrels capture rainwater that flows off your roof for use in the landscape. They're easy and inexpensive to make and can have a big impact on your water bill-instead of watering your plants with water you're paying for, you're using free water!
After establishment, most landscape plants will require a little supplemental irrigation during the dry parts of the year.
