How hard is the water in North Las Vegas?

North Las Vegas water has a hardness level of 17 GPG (291 PPM), which is classified as "Very Hard." This is identical to the broader Las Vegas Valley since all water comes from the same LVVWD system.

Does North Las Vegas have its own water utility?

No. North Las Vegas receives drinking water from the Las Vegas Valley Water District (LVVWD). However, the city maintains its own wastewater utility and groundwater rights (6,201 acre-feet/year). The City of North Las Vegas Utilities Department handles sewer services and publishes its own annual water quality reports.

Where does North Las Vegas get its water?

Approximately 90% of North Las Vegas water comes from the Colorado River via Lake Mead, treated at SNWA facilities. The remaining 10% comes from local groundwater wells, increasing to up to 25% during peak summer demand. Both sources have similar hardness levels.

Is North Las Vegas water the same as Las Vegas water?

Yes. North Las Vegas and Las Vegas proper receive the same water from LVVWD, treated at the same facilities. Water hardness (17-18 GPG) is identical across both cities. The only difference is that North Las Vegas maintains its own groundwater wells for supplemental supply.

Do I need a water softener in North Las Vegas?

With water hardness at 17 GPG, a salt-based water softener is highly recommended. The hard water causes scale buildup in pipes and appliances, reduces soap effectiveness, and leaves spots on dishes. Set your softener to 17-18 GPG to match local conditions.

Is North Las Vegas water safe to drink?

Yes, North Las Vegas water meets or exceeds all EPA and state safety standards. LVVWD conducts over 320,000 water quality tests annually. Water hardness (calcium and magnesium) poses no health risks—it's an aesthetic and practical concern, not a health one.

What This Means For You

At 17 grains per gallon (GPG), North Las Vegas has very hard water—identical to the broader Las Vegas Valley. This is because North Las Vegas receives its drinking water from the Las Vegas Valley Water District (LVVWD), the same utility serving Las Vegas.

North Las Vegas receives treated water from the Las Vegas Valley Water District (LVVWD), sourced primarily from Lake Mead. The city maintains its own groundwater rights (6,201 acre-feet/year) and operates wells that can contribute up to 25% of supply during peak summer demand. Water is treated at SNWA facilities including the Alfred Merritt Smith and River Mountains treatment plants.

While hard water is completely safe to drink (calcium and magnesium are essential minerals), it causes practical problems in homes: scale buildup in pipes and water heaters, reduced appliance efficiency, spotty dishes, dry skin and hair, and the need for more soap and detergent.
