Atlanta Tap Water: It Comes from Lake Lanier
Both Gwinnett County and the City of Atlanta supply treated Lake Lanier water. Official reports show it meets federal standards and is very soft, with minimal minerals.
U.S. Geological Survey (USGS) scale: 0–60 soft, 61–120 moderate, 121–180 hard, 181+ very hard. The Gwinnett figure converts its 1.34 gpg average; other areas use official water agency data.

A Water Purifier Before a Softener
Metro Atlanta tap water is soft and low in hardness, so scale is rarely a concern. For most households, a purifier for better-tasting drinking water comes first.
Chlorine Taste and Odor
Gwinnett County disinfects with chlorine and maintains residual chlorine through distribution. It stays within safety standards, but some households are sensitive to the taste and odor.
Seasonal Earthy Odor
The City of Atlanta notes that naturally occurring substances in the reservoir can cause an earthy smell. It's not harmful, but there are times of year when the taste bothers people.
These figures are system-wide data published by the agencies; actual water quality at your home may vary by water provider, season, and building plumbing. Check your local water provider's annual quality report for precise figures.

Do you install in Duluth or Suwanee too?
Yes — installation is available across Gwinnett County, including Duluth and Suwanee, as well as Johns Creek, Alpharetta, and downtown Atlanta. For outlying areas like Athens, send us your address and we'll confirm availability.
Is Atlanta tap water safe to drink as is?
Gwinnett County's 2025 report shows no federal Safe Drinking Water Act violations, and the City of Atlanta states its tap water meets EPA standards. Households usually choose a purifier for chlorine taste or seasonal earthy odor concerns.
Do I need a water softener in Georgia too?
Gwinnett County averages 1.34 gpg — soft water — so a purifier comes first for most households. Homes on private wells outside the metro should decide on a softener based on a water test.
Can I install in a townhouse or apartment?
Most homes can be fitted, but renters should check with their landlord or management office first. We'll recommend the right model for your home — countertop or undersink — during your consultation.
How are filters maintained after installation?
During your rental, a Coway specialist visits every 6 months to replace filters and inspect your products. Maintenance is included in your rental fee.
