Water Treatment Services Indianapolis
We install, repair, and service water softeners, whole-house filters, and reverse osmosis systems for homes across Indianapolis and Carmel, Fishers, Noblesville, Westfield, and Greenwood. Indianapolis tap water averages 19 grains per gallon, which is "very hard" by the USGS scale. Tell us what you are seeing at the tap and we will size the fix to your actual water, not a guess.
Why Indianapolis homes need water treatment
Citizens Energy Group, which supplies about 900,000 people across Central Indiana, reported a 2025 system average of 317 parts per million of hardness (19 grains per gallon) across Indianapolis and Morgan County. The system ranges from 148 to 460 ppm (8.7 to 27 gpg) depending on which plant serves your address.
The USGS classifies anything above 180 mg/L as "very hard," so the Indianapolis average sits well inside that band. That is what causes the spotting on glassware, the film on shower doors, the stiff laundry, and the scale that builds inside a water heater.
Hardness is not one number across the metro, which is why we measure before we quote. Carmel Utilities, for instance, softens its water at the plant to roughly 8 grains before it reaches the house, still enough to want a softener for zero-grain water, but a different starting point than an address on the Citizens system.

Indianapolis & Morgan County water quality data, Citizens Energy Group
How hard is the water in Indianapolis?
Citizens Energy Group reported a 2025 average of 317 ppm (19 grains per gallon) for Indianapolis and Morgan County, with a system range of 8.7 to 27 gpg. The USGS calls anything over 180 mg/L "very hard," so Indianapolis is comfortably in that category. Your exact number depends on which treatment plant serves your address.
Will a water softener fix the chlorine taste in my water?
No. A softener removes calcium and magnesium. It does not address taste or odor from disinfection. Citizens adds chlorine and a small amount of ammonia so the chlorine persists through the distribution system. If taste is your complaint, carbon filtration or a reverse osmosis system at the sink is the right tool.
Do you need a plumbing license to install a water softener in Indiana?
Indiana Code 25-28.5-1-2 expressly excludes the sale and installation of water softening equipment from the statutory definition of plumbing. We make no licensing claims and do not present ourselves as licensed plumbers. We do the work the statute describes, and we size and install equipment to the manufacturer’s specification.
