Illustration of drip head says "drip it, don't drown it - plants and trees need MUCH LESS WATER than grass"

In spring, we recommend watering plants on drip systems 1-2 days per week, with duration depending on emitter flow. Grass on sprinkler systems can be watered up to 3 days per week, for 12 minutes total per assigned watering day.

What you can do to conserve

Drought and climate change have caused Lake Mead to drop about 170 feet. The federal government has issued a tier two water shortage declaration, reducing the amount of water Southern Nevada is allowed to draw from the lake. We're asking everyone to help protect and extend our community's primary water supply.

Change your watering clock

Our community loses billions of gallons each year due to overwatering, and too much water is harmful to turf, trees and shrubs.

Follow the mandatory seasonal watering restrictions to save water, improve the health of your landscape and avoid water waste fines.

New rules protect our limited water supply

Southern Nevada's water supply situation is changing, and the rules are too. Stay in the know.

Legislation prohibits the use of Colorado River water to irrigate nonfunctional turf

A law prohibits irrigation of nonfunctional grass beginning in 2027. This initiative will save our community billions of gallons of water per year. The law does not apply to grass in a homeowner's yard. From tips and tools to rebates and resources, we're happy to help.

Laws & Ordinances

Code changes to limit residential pool sizes

Ongoing drought and climate change conditions continue to affect water levels in Lake Mead – Southern Nevada's primary water supply. As a result, the federal government declared a shortage on the Colorado River, reducing Southern Nevada's available water supply by 8.1 billion gallons, and additional reductions are expected in the coming years.

To help manage these water supply constraints, the Southern Nevada Water Authority approved a resolution in July 2022 that supports a 600-square-foot surface area limit on new residential pools. The Las Vegas Valley Water District and other local jurisdictions approved this change shortly thereafter with rule and code changes.

Water quality

The SNWA uses cutting edge technology to ensure your water is treated and tested to the utmost standards of safety. View water quality reports.

The SNWA also is helping researchers around the world learn more about the presence of coronavirus in communities. The research we're conducting confirms that genetic markers of COVID-19 can be detected in wastewater before the water is treated but are removed during the treatment process.

Treatment & Testing

Infrastructure and treatment facilities

Southern Nevada's water system consists of intake, transmission, treatment and wastewater processes, including state-of-the-art laboratory facilities. 

The SNWA has undertaken several massive construction projects over the years to protect our community from declining water levels at Lake Mead, and to ensure water infrastructure and treatment facilities work as effectively and efficiently as possible.
