The drip irrigation system can be operated by hand at regular intervals or set to automatically go on and off at the schedule the homeowner chooses. The amount of water produced by the individual emitters can be adjusted as well, providing just the amount of water for each plant in the landscape.
The design of the individual water emitters varies, and it is important to choose the right one for your individual landscape. There are drippers that provide a small amount of water all the time while the system is turned on, microbubblers that bubble up at regular intervals and microsprayers that give plants a gentle spray of water.
When you shop for a drip irrigation system, you will see that its capacity is expressed in terms of gallons per hour. Each drip irrigation system can be individually calibrated, making it easy to adjust the amount of water used.
