Can I Drink Tap Water in Las Vegas?

Las Vegas Valley Water District publishes annual water quality information, and SNWA explains that the region's primary source is the Colorado River via Lake Mead. The water is heavily treated and regulated, making it safe for most visitors to drink. The main issue in Las Vegas is taste and hardness, not basic potability, so filters are often used for comfort.

Las Vegas relies primarily on Colorado River water from Lake Mead, and Southern Nevada utilities publish source and treatment information for customers. The Las Vegas Valley Water District (LVVWD) provides annual water quality report access, while the Southern Nevada Water Authority (SNWA) explains the region's source-water system. This is a highly managed municipal supply with modern treatment and regulatory oversight. In practice, Las Vegas tap water is safe for drinking, brushing teeth, and restaurant ice, but many people dislike the taste because the water is very hard and mineral-rich. Visitors often choose filtered water or bottled water for flavor, especially during long stays. In a desert environment, hydration is a bigger concern than tap-water safety for most travelers, so having easy access to water at all times is more important than avoiding tap water on health grounds.

Las Vegas is a low-risk city for tap water safety, but not always a favorite for taste. You can usually drink tap water safely in hotels and residences, use it for brushing teeth, and accept ice without concern. If you dislike the flavor, use filtered or bottled water. Because dehydration risk is high in the desert, prioritize drinking enough water throughout the day and night.
