Where Las Vegas water comes from

Most homes in the city are served by the Las Vegas Valley Water District (LVVWD), which has delivered water to the valley since 1954 and now serves more than 1.7 million people. According to LVVWD, about 90% of Southern Nevada’s drinking water comes from Lake Mead and the Colorado River, and about 10% comes from groundwater. That mix is not fixed all year: from June through September, groundwater pumped from district wells can make up as much as 25% of the valley’s daily supply to meet peak summer demand.

Groundwater is how Las Vegas started. The Springs Preserve sits on the site of the original Las Vegas springs, which stopped flowing by 1962 after decades of heavy pumping lowered the water table.

Common water problems in Las Vegas homes

LVVWD rates local water as very hard, at roughly 280 to 291 parts per million, or about 16 to 17 grains per gallon. The district notes that the calcium and magnesium carried by the Colorado River can leave chalky build-up on fixtures and spots on glassware, and that these effects are aesthetic, not a health risk. For comparison, water over 180 mg/L is generally classed as very hard.

  • Scale: white crust on shower heads, faucets, and glass doors, plus mineral build-up inside water heaters, dishwashers, and ice makers.
  • Chlorine taste and smell: LVVWD adds chlorine as water leaves its treatment facilities to protect it on the way to your tap. It is there for a reason, but many people prefer to filter it out.
  • Dry skin and dull hair: hard water makes soap harder to rinse off, which many homeowners notice right away.
  • Bottled water habit: a lot of families buy water by the case because they do not like the taste. That is why we ask, “Why pay for water twice?”

Las Vegas water FAQ

Is Las Vegas tap water safe to drink?

Yes. LVVWD treats and monitors the water, and hardness is an aesthetic issue rather than a safety one. Many people still filter it for taste. We cover the most common complaints in our post on problems with Las Vegas drinking water.

Does a Brita-style pitcher fix hard water?

No. LVVWD notes that carbon filters do not remove hardness, minerals, sodium, or fluoride. You need a softener or scale control system for hardness, and reverse osmosis for drinking water.

Do you serve the rest of the valley?

Yes. Beyond the city, we work in Summerlin, North Las Vegas, Henderson, and the rest of Southern Nevada.
