As winter makes its way into Southern Nevada, change your watering clock now to water only on your 1 assigned day per week in accordance with the community’s mandatory seasonal watering schedule, in effect November 1 through February 28. It’s one of the best ways to conserve water in Southern Nevada and it’s the law!

Winter restrictions limit spray and drip irrigation to one day per week based on your property’s address; find your assigned watering day at Sunday watering is prohibited year-round. Watering on days other than your assigned watering is considered water waste and may result in a costly water-waste fees ranging from $80 to as much as $5,000 for repeat violations.

Following with the winter restrictions takes on added importance this year as a Tier 2 shortage declaration on the Colorado River will reduce the amount of water Southern Nevada can draw from Lake Mead by more than 8 billion gallons beginning January 1. Find more conservation tips at
