With hot summer days around the corner, the Southern Nevada Water Authority (SNWA) is reminding the community that mandatory summer watering restrictions are 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. You can reduce the amount of water lost to evaporation by watering in the early morning or in the evening. As a reminder, Sunday watering is prohibited year-round.

By maintaining a three-or four-day watering schedule and slowly adding watering days as the summer heat increases, you can help reduce water use, save money on your water bills, and keep your landscape vibrant and healthy.

To prevent water waste, grass should be watered in three cycles of four minutes each set one hour apart, for a maximum of 12 minutes daily. That’s all your grass needs. In addition, over-watering plants and shrubs with drip irrigation can do more harm than good, as most plants can thrive when watered less often, such as on a two-or three-day per week summer schedule. Drip systems typically run for 30 to 90 minutes, depending on the flow rate of the emitters.

Watering during prohibited times or allowing water to spray or flow off your property is considered water waste and may result in a water-waste fee. Contact your water provider for complete details.

An easy way to get smart about landscape irrigation is by investing in a smart irrigation controller, which automatically adjusts your watering according to weather conditions. Many smart controllers can be accessed via apps on your mobile devices. To help defray the cost, the SNWA offers a rebate of 50 percent off the purchase price or up to $100, whichever is less.
