We rely on your to help save our aquifer. From now until March 11, 2023, watering residential lawns drops to once a week . Watering between 10:00am and 4:00pm leads to rapid evaporation and less absorption, so try to water overnight and not for more than an hour. Orange County homes with odd-numbered addresses water on Saturdays, even-numbered addresses water on Sundays, and nonresidential properties on Tuesdays. Every drop counts!
