Do you support mandatory one-day-per-week winter watering restrictions to help lower your monthly water bills?
Starting November 1, 2026, residents and businesses across the Las Vegas valley must shift to winter watering schedules mandated by the Southern Nevada Water Authority. The new rules prohibit all sprinkler irrigation on Sundays and limit watering to one day per week through the end of February.
Why it matters
These seasonal restrictions are designed to conserve the region's finite water supply while helping households and businesses lower their monthly utility costs. By adhering to the winter schedule, customers can manage their outdoor water usage more effectively during the cooler months.
Following the updated winter irrigation schedule can result in annual savings of up to $300 per customer. Irrigation for drip systems should be adjusted to a frequency of every seven to 14 days throughout the season.

The details
Under the new mandate from the Southern Nevada Water Authority, irrigation clocks must be set to ensure no sprinkler usage occurs on Sundays. Residents are encouraged to schedule grass watering during mid-morning hours to maximize efficiency. These rules apply valley-wide and remain in place until the end of the winter cycle, with drip systems required to operate significantly less often than standard turf irrigation.

Beyond the Strip
This transition to winter-specific irrigation follows the established seasonal conservation mandates practiced across the Las Vegas valley for years. It reinforces the regional commitment to curbing outdoor water waste during months where evaporation rates drop.
Check your irrigation controller settings before November 1 to ensure your system is compliant with the one-day-per-week limit. Remember that your sprinklers must remain off every Sunday throughout the winter months to avoid potential penalties.
The takeaway
Winterizing your landscape is a key step in reducing your monthly utility bill as outdoor water demand shifts. Set a reminder to check your irrigation controller on October 31 to ensure you are ready for the November 1 transition.
