Aurora Water Treatment
Water Softener and Filtration in Aurora, IL
Aurora’s 2025 municipal report says the Aurora Water Treatment Plant uses Fox River surface water along with a blend from shallow and deep wells. The same report lists a hardness range of 110–160 mg/liter (6–10 grains per gallon). Windy City Water Pros can help you consider a whole-home setup for your Aurora home after discussing your goals and evaluating the installation. A utility report describes the public system. It is not a reading from one home's tap, where plumbing, fixtures, sample location, and existing treatment can change the experience.

What Aurora's report lists
- The report lists a tap-water hardness range of 110–160 mg/liter (6–10 grains per gallon).
Hardness has no EPA health limit. It is mainly useful for discussing scale, fixtures, soap use, and how water feels in daily use.
This municipal water-quality report describes the Aurora water system and reported sampling. It does not determine water conditions at an individual home, which can be affected by building plumbing, service-line material, fixtures, and local conditions.

Aurora water-treatment FAQs
Town FAQ source: 2025 Water Quality Report — City of Aurora, Illinois (2025)
Where does Aurora municipal water come from?
Aurora’s 2025 Water Quality Report states that the Aurora Water Treatment Plant uses surface water from the Fox River and a blend of water from several shallow and deep wells drawing from the Cambrian-Ordovician Aquifer system.
What hardness does Aurora list in its latest water report?
The City’s 2025 report lists a tap-water hardness range of 110–160 mg/liter, or 6–10 grains per gallon. That municipal figure does not by itself establish conditions at a particular Aurora home.
How does Aurora say its municipal water is treated?
The 2025 report says well water is combined with Fox River water at the plant, then lime-softened, fluoridated, filtered, disinfected, and sent to reservoirs.
Does Aurora’s water report tell me what is happening at my faucet?
Not by itself. It describes the Aurora municipal system and reported sampling; water conditions at a home can also be affected by its plumbing, service-line material, fixtures, and local conditions.
