Hard water refers to water that has very high mineral content. It generally contains higher-than-normal levels of calcium and magnesium, with other trace minerals present as well. The hardness of the water in a specific area is measured by how much of these minerals are present.

If you live in Las Vegas, you know hard water is part of life in Southern Nevada. But how hard is our water and how does it compare to other regions in the nation? Our water filtration experts explain.

Las Vegas Hard Water Rating

According to Las Vegas Valley Water District (LVVWD)1, Las Vegas has a hardness rating of 278 parts per million or 16 grains per gallon. This level of hardness is considered to be “extremely hard.” In fact, Las Vegas has some of the hardest water in the country! A study published by Homewater 101 even shows that we rank second in the nation2 for the hardest water in the United States (following Indianapolis, according to the study).

While it’s safe to consume and use for laundry, bathing, and cleaning, hard water can lead to a number of issues for your home and appliances. Luckily, a good water softener can help Southern Nevada residents avoid the negative effects of hard water.

Why Is the Water in Las Vegas Hard?

As much as 90% of the water supply in Las Vegas3 comes from Lake Mead. As the snow on the Rocky Mountains melts, this water enters the Colorado River and picks up dissolved minerals as it flows over ancient seabeds, limestone rocks, and through mineral-dense canyons to Southern Nevada.

By the time the water reaches Lake Mead, there is a very high mineral content present. For this reason, many Las Vegas residents invest in a water softener to combat the effects of mineral-heavy water.

How Do You Know You Have Hard Water?

If you’re new to the Las Vegas area or you’ve never had to deal with hard water, you might not know the signs that show you have hard water in your home. If you have hard water, you may notice:

  • White, chalky buildup on your faucets and fixtures.
  • Your clothing looks dull or worn out.
  • Your shampoo and soap may not be foam up or properly rinse off.
  • Your hair and skin may be dry or irritated.
  • Your dishes, plates, and glassware look spotted and dingy.

While your hard water may not be bothering you right now, it can do some damage to your pipes and appliances over time. The mineral buildup can make appliances less efficient, and you may even notice your water bill is higher than usual.

What Can Be Done About Hard Water in Las Vegas?

No matter how hard the water in Las Vegas might be, there are some steps that you can take to rectify the issues in your home and prevent hard water issues in the future:

Water Softening Systems

A water softening system is the ideal piece of equipment to have installed in your Las Vegas home or office. A water softener will remove the hard minerals from your water using the process of ion exchange.

Rain Water of Las Vegas has designed our custom water softeners specifically for hard Las Vegas water. They can handle the heavy concentration of calcium and magnesium in your water before it even enters your home. Contact our team today to learn more!

Water Conditioning Systems

A water conditioning system is an excellent way to combat the effects of hard Las Vegas water. However, a water conditioner doesn’t just soften the water—it also filters the water and removes toxins, pollutants, and chemicals found in tap water.

Special Cleaning Supplies

If you don’t have a water softener yet and are dealing with water hardness, there are cleaning supplies made specifically to remove rust, limescale, and calcium stains on your fixtures, faucets, sinks, tubs, and toilet bowls. You can also look into:

  • Rinse aids for your dishwasher
  • Bath salts (such as Epsom salts)
  • Laundry detergents with water-softening ingredients

Although these cleaning supplies can help with the effects of hard water, they do not address the cause. Consider installing a water softener or water conditioning system to remove the minerals in the water before it flows into your home.
