Water Restrictions in Nevada– 2026
Published:
Managed by Local and regional authorities.
Nevada Overview
Nevada uses a group-based seasonal watering schedule— unlike any other state. Instead of odd/even address days, every property is assigned to a watering group (A through F) based on geographic location. Your group determines which days you can water, and the schedule changes with the seasons:
- Spring (Mar 1–Apr 30) – 3 days per week
- Summer (May 1–Aug 31) – Up to 6 days per week (no watering 11am–7pm)
- Fall (Sep 1–Oct 31) – 3 days per week
- Winter (Nov 1–Feb 28) – 1 day per week
No watering on Sundays — ever, any season.Sprinklers are limited to 12 minutes per day using the “12-minute method”: three 4-minute cycles with 1 hour between each cycle to prevent runoff on desert-hardpan soil.
2027 Nonfunctional Turf Ban:Nevada AB 356 (2021) prohibits use of Colorado River water to irrigate nonfunctional grass at commercial, multi-family, HOA, and government properties starting January 1, 2027 — the first such ban in the US. Single-family residential yards are exempt. Rebates up to $5/sq ft are available for qualifying conversions.
The Colorado River supplies ~90% of Southern Nevada’s water. Despite adding 750,000 residents since 2002, SNWA has cut per-person water use by 48% through this mandatory group-based system.
Watering Your Nevada Lawn During Restrictions
Nevada’s water restrictions are the most aggressive in the continental United States, and Las Vegas lawns face a fundamentally different future than most American turf. The Southern Nevada Water Authority’s turf-replacement program has already converted millions of square feet of decorative grass, and remaining residential lawns must function within tightly managed water budgets.
For Bermuda Grass lawns under Stage 2 restrictions, deep watering once per permitted day at early-morning hours is the optimal approach — Bermuda’s root system can access soil moisture at 30 cm depth, far below what shallow daily watering achieves. Maintain Bermuda at 40–50mm to maximise the natural drought tolerance that makes it appropriate for Nevada’s climate. Skip the scheduled watering day entirely after any 0.25"+ rainfall, and never water in the 11 AM–7 PM summer blackout window.
The Nevada Division of Water Resources (water.nv.gov) and the Southern Nevada Water Authority (snwa.com) both provide landscape water-budget tools that calculate your property’s water allocation based on square footage and plant type. Reno homeowners can use the Truckee Meadows Water Authority’s WaterSmart program (tmwa.com/watersmart) for free irrigation audits and rebates on efficient irrigation upgrades; audits routinely identify 20–30% water savings on properties built before 2005.
Nevada homeowners considering turf conversion qualify for SNWA’s Water Smart Landscapes Rebate of $3 per square foot for residential conversions, up to 5,000 square feet per property. Commercial conversions receive $5 per square foot. The rebate has funded over 215 million square feet of conversion since 1999 and is the primary reason SNWA has cut per-person water use by 48% despite adding 750,000 residents since 2002.
