Reno Water Hardness at a Glance
Reno, NV — Water Hardness Data
This city's hardness sits above the national average.
Why Is Reno Water So Hard?
Reno draws from the Truckee River, which originates at Lake Tahoe in the Sierra Nevada. Lake Tahoe water is quite soft (Sierra Nevada granite dissolves few minerals), but the Truckee flows east into Nevada's Basin-and-Range terrain, where limestone and volcanic sediments add mineral content before reaching Reno's intake. The result is water harder than Pacific Northwest cities but softer than true desert-aquifer cities.
The USGS classifies Reno's 8–14 gpg as Hard.

What Hard Water Does to a Reno Home
At 8–14 gpg, scale damage in Reno is noticeable. Here's what that looks like in practice:
- Water heaters: The US Department of Energy estimates scale reduces water heater efficiency by up to 30% for every 5 gpg of hardness. Tank and tankless units accumulate scale on heating elements and heat exchangers, forcing them to work harder.
- Dishwashers: White film on glasses and dishes is common. Spray arm ports clog with scale, reducing cleaning performance — see our guide to hard water and dishwashers for solutions short of a full softener.
- Showerheads and faucets: Visible white mineral deposits accumulate on fixtures. Flow rates drop as scale narrows openings. See our guide on hard water and hair for tips on protecting hair and skin.
- Pipes (older homes): Calcium carbonate deposits gradually narrow pipes over years, reducing pressure in homes over 15+ years old.
- Skin and hair: Mineral film on skin after showering and dull, brittle hair are common complaints. Those with eczema may see flare-ups — see our hard water and eczema guide.
- Coffee and tea: High mineral content affects extraction and flavor. Hard water and coffee — what the science says.
Best Water Treatment for Reno Homes
At 8–14 gpg, a whole-home water softener is worth considering to protect appliances and plumbing. The EPA's Consumer Confidence Report program requires City of Reno / Reno Water to publish annual contaminant data — check it for your specific address.
