It’s that most wonderful time of the year—for saving water! As winter begins to settle in, change your watering clock to follow the community’s mandatory winter watering schedule, in effect November 1 through February 28.

During the winter, sprinkler irrigation is limited to one assigned day per week and Sunday watering is prohibited. Our chilly days and nights give us the best opportunity to conserve water—and it’s the law! Following the seasonal water schedule will help you manage your water bill and avoid costly water-waste fees. Don’t waste water!

By following these simple tips, you can avoid over-watering your landscape—and maintain the health and vitality of your plants and trees in the cold months ahead:
• Water grass for a total of 12 minutes on your watering day in three cycles of four minutes each, set one hour apart, to avoid water waste and runoff.
• Water during the mid-morning hours to avoid freezing and prevent ice from forming on lawns and sidewalks.
• Run drip irrigation once every seven to 14 days, as water-efficient trees and plants need much less water than grass.
• Change the time on your irrigation clock to coincide with the end of Daylight-Saving Time on Sunday, November 5.
• You could save up to $300 annually on your water bills by following the seasonal watering restrictions year-round.

Although a wet winter combined with lower water demands increased Lake Mead water levels this year, it’s important to know that one good year of favorable hydrology will not reverse the decades-long drought along the Colorado River—Lake Mead levels are still down more than 140 feet. Saving water is crucial for our community!
