About half of the water used by villas is for landscape irrigation, but many villas use more than twice as much irrigation water than is needed. Avoid watering plants in the middle of the day when much of the water evaporates before it can be used by the plants. The best time to water your plants is in the early morning. Using a timer to turn irrigation water on and off can save a large amount of water. Drip irrigation systems are the most efficient for plants, shrubs, and trees. Installing a well-designed irrigation system can save hundreds of liters of water per day. In the winter, most plants need only one-half to one-third of the water needed in the summer. If you have an irrigation system, be sure to check it for leaks and other problems at least twice a year.
