Fishers Water Softeners, Sized to Your Utility's Numbers
Two utilities pipe water into Fishers homes, and both deliver hard water. The real questions are how much softening your house needs, which extras are worth it, and what a fair price looks like.
Fishers water is hard no matter which utility serves you. Citizens Energy Group reported a 2025 average of 19 grains per gallon (317 mg/L), and Indiana American Water lists 20 to 23 gpg for the groundwater system that covers part of Fishers. A salt-based softener typically costs $1,200–$3,800 installed (HomeGuide).
Check which utility is on your bill
The City of Fishers tells new residents there are two public water suppliers in town, Citizens Energy Group and Indiana American Water, and that the bill is the way to know which one you have. That matters, because the two draw from different sources.
Citizens runs the big Indianapolis-area system, fed mostly by the White River and Fall Creek, with reservoirs such as Geist and Morse holding supply, plus several groundwater plants (Citizens Energy Group). Indiana American Water's Noblesville Operations pumps groundwater from 12 wells in four well fields, and its water quality sheet lists Fishers ZIP 46038 among the areas it serves (Indiana American Water). A ZIP code isn't a service boundary, though. Go by the name on the bill.
The hardness figures, side by side
- Citizens Energy Group: 317 mg/L average in 2025, which Citizens rounds to 19 grains per gallon. Across the whole system, samples ran from 148 to 460 mg/L (8.7 to 27 gpg), because each treatment plant draws on different source water.
- Indiana American Water, Noblesville Operations: typically 350 to 400 mg/L, or 20 to 23 gpg. Its 2025 report lists plant averages of 385, 420 and 467 ppm, roughly 23 to 27 gpg by our conversion.
For scale, the U.S. Geological Survey calls anything above 180 mg/L very hard. Both suppliers sit well past that line. The Fishers water quality report guide walks through the rest of each report.

What 19 to 27 grains does inside a house
At these levels, scale shows up fast: crust on shower glass, white film in the dishwasher, faucet aerators that clog, and a layer of mineral at the bottom of the water heater that makes it work harder. Tankless water heaters and high-efficiency appliances are especially sensitive to it.
Fishers' housing adds a twist. The median home was built in 2002, and about 61% of homes went up between 1990 and 2009 (U.S. Census ACS 2020-2024). Any softener put in when one of those houses was new is now somewhere between 15 and 30 years old. Some just need a valve or resin; others are undersized for a family that's grown into the house.
Beyond softening: taste, drinking water and PFAS
A softener removes calcium and magnesium. It doesn't change taste much. Citizens disinfects with chlorine and adds a small amount of ammonia so the chlorine lasts longer in the pipes (Citizens Energy Group), and some people notice that at the tap. A whole-home carbon filter handles taste and odor; reverse osmosis at the kitchen sink handles drinking water.
On PFAS, the reports are specific. Citizens tested treated water for 17 PFAS in 2025 and found two, PFBS at an average of 0.73 parts per trillion and PFHxA at 0.63 ppt; the other 15 weren't detected. Indiana American's federal UCMR 5 sampling found one, PFPeA, at 3.3 ppt at one of its three plants. Neither report lists PFOA or PFOS, the two PFAS with EPA limits of 4 ppt each. Filtration is a choice here, not an emergency.
How requests are handled
Fishers Water Softener Co. doesn't sell or install equipment. It's an independent local resource. When you ask for a water test, your request goes to one vetted, independent water treatment specialist who serves Fishers and calls you back to set a time. Indiana's plumbing licensing law states that its definition of plumbing does not include the sale or installation of water softening equipment (Indiana Code 25-28.5-1-2). That exclusion names softeners only, so for filters, RO or new piping, ask who will do the plumbing work. Typical installed prices for every option are on the Fishers water softener cost page.
Questions homeowners ask
Is Fishers water hard?
Yes. Citizens Energy Group's 2025 average was 19 grains per gallon, and Indiana American Water lists 20 to 23 gpg for its Noblesville system, which serves part of Fishers. Anything over about 10.5 gpg (180 mg/L) is very hard on the USGS scale.
How do I know which utility serves my address?
Look at the water bill. The City of Fishers says the town has two suppliers, Citizens Energy Group and Indiana American Water, and points residents to the bill to tell them apart.
Will a softener fix a chlorine taste?
No. Softening swaps hardness minerals out; it leaves disinfectant taste alone. A carbon filter, either whole-home or under the sink, is what changes taste and smell.
My house came with a softener. Is it worth keeping?
Often, yes. If the tank is sound, a new control valve or fresh resin can bring an older unit back for far less than replacement. A free visit checks capacity against your household's use before anyone suggests a new system.
