As summer approaches, the Southern Nevada Water Authority (SNWA) is reminding residents and businesses to continue their support in conserving our

region’s precious water resources by following the community’s mandatory summer watering restrictions, in effect May 1 through August 31.

• The summer restrictions prohibit spray irrigation between 11 a.m. and 7 p.m. when water can be lost to intense heat and high winds.
• Watering in the early morning or evening reduces the amount of water lost to evaporation.
• Watering during prohibited hours or allowing water to spray or flow off your property is considered water waste and may result in a costly fine.
• Irrigate grass with pop-up sprinklers for a maximum of 12 minutes per watering day, set in three four minute cycles, spaced one hour apart. That’s all your grass needs.
• And remember, Sunday watering is prohibited year-round.

Over-watering plants and trees with drip irrigation can do more harm than good, as most plants and trees can thrive when watered less often, such as on a two or three-day per week summer schedule. These water-efficient plants have distinct needs compared to grass and can thrive on less water even in hotter conditions. Drip systems typically run for 30 to 90 minutes, depending on the flow rate of the emitters. By following seasonal watering restrictions year-round, you can save up to $300 annually on your water bills.
