The Southern Nevada Water Authority's spring watering schedule starts on Tuesday.
Mandatory watering restrictions limit landscape irrigation to three assigned days per week from March 1 through April 30, based on each customer's assigned watering group. Watering restrictions also apply to drip irrigation.
Sunday is not an optional watering day. To determine your watering group, and to learn more about how often and how long to water your landscape, visit snwa.com.
Customers also are reminded to change the clocks on their irrigation timers and adjust their irrigation start times when Daylight Saving Time begins Sunday, March 13.
