Who provides water in Goodyear?
| Area | Provider | Main sources |
|---|---|---|
| Most of the area north of I-10 | Liberty Utilities (PWS 04-07-046) | Groundwater from the West Salt River Valley aquifer |
| South of I-10 | City of Goodyear (PWS 07-094) | Groundwater plus Colorado River water treated at the city's surface water plant |
City of Goodyear Water Services FAQs and 2022 report; Liberty Utilities' report on 2025 water quality.
Your water bill is the quickest check, and the city has a water and sewer service area lookup on its website. The city says "most" of the area north of I-10, not all of it, so confirm before you size a softener. Some West Valley neighborhoods are also served by EPCOR's Agua Fria district, which reports 2 to 17 gpg and says it covers parts of several cities without naming them.
How hard is Goodyear water?
| Provider | As reported | Converted | Year |
|---|---|---|---|
| Liberty Utilities | 233 ppm as CaCO3 (range 150 to 360); 13.6 grains/gal (range 8.8 to 21.1) | Both units reported | 2025 data |
| City of Goodyear: softener advice | Set softener hardness to 14 to 20 grains per gallon | About 239 to 342 mg/L | 2025 report |
| City of Goodyear: last listed result | 18 grains/gallon (range 4 to 49) | About 308 mg/L (68 to 838) | 2022 report |
Liberty's single figure is labeled "highest result or highest average". The city's 2022 figure is listed as a running average or highest value. Its 2023 to 2025 reports give the softener advice but no hardness result. Conversions are ours at 17.1 mg/L per grain.
Either way, Goodyear water is very hard: the University of Nebraska-Lincoln scale starts "very hard" at 10.5 gpg. The city's FAQ adds that hardness varies throughout the city and that there's no primary or secondary standard for it. A city range as wide as 4 to 49 gpg in 2022 is a strong reason to test your own tap. See how Goodyear compares in our Phoenix water hardness guide.
Setting and sizing a softener in Goodyear
The city's 14 to 20 gpg advice is a useful starting range for city customers; Liberty customers should start from a tap test; Liberty's 2025 range of 8.8 to 21.1 gpg overlaps the city's advice. Our arithmetic, for illustration: a four-person home using the EPA's average 82 gallons per person per day at 14 gpg asks a softener to remove about 4,590 grains a day; at 20 gpg, about 6,560.
Use our softener sizing worksheet to run your own household, and ask installers which hardness they used. Comparing a softener with a conditioner, filter or RO? See our water treatment decision matrix.
Goodyear notes: HOAs, coolers and RO water use
- HOA rules. In 2011 testimony to an Arizona legislative committee on water salinity, the only softener restrictions anyone could name were self-imposed HOA or developer rules, with Goodyear among the examples. That's old and we couldn't confirm a current rule, so check your CC&Rs.
- Evaporative coolers. A hardness fact sheet hosted by the City of Goodyear says cooler pads may need changing twice a season with hard water, and recommends keeping the bleed-off valve adjusted.
- RO water use. The city's 2025 report notes that reverse osmosis units can use up to 5 gallons of water to make 1 gallon. If you add reverse osmosis, ask about the model's efficiency.
- Sodium. Softening adds sodium or potassium. The city's 2025 report lists sodium at 139 ppm (86 to 300), and Liberty's at 120 ppm (65 to 210), before any softening.
Water softener cost in Goodyear
We haven't found Goodyear-specific price data, so these are Angi's Phoenix-area ranges: about $1,550 on average installed, single-tank softeners at $550 to $2,000, dual-tank at $1,100 to $5,500, and $800 to $3,500 in added plumbing when there's no softener loop. Very hard water can push you toward higher-capacity units, which Angi lists at about $1,800 to $5,500.
Goodyear has many newer master-planned neighborhoods, and newer homes are more likely to have a garage softener loop; confirm yours. Already own a softener that isn't keeping up? See water softener repair or replacement. Every line item is in our water softener cost guide.
On Liberty or city water? Either way, licensed Goodyear companies can test your tap and quote a softener sized for it.

Goodyear water softener FAQs
What is the water hardness in Goodyear, AZ?
It depends on your provider. Liberty Utilities, which serves most of the area north of I-10, lists 233 ppm (13.6 gpg) with a range of 8.8 to 21.1 gpg in its 2025 data. The City of Goodyear's 2025 report gives no hardness result but advises setting softeners to 14 to 20 gpg; its 2022 report listed 18 gpg.
Who provides water north of I-10 in Goodyear?
The City of Goodyear's FAQ says most of the area north of I-10 is served by Liberty Utilities, while the city's own water service covers the south side. Check your water bill or the city's water and sewer service area lookup, because the city says most, not all, of the north side is on Liberty.
What should I set my water softener to in Goodyear?
City of Goodyear customers can start with the city's advice of 14 to 20 grains per gallon. Liberty customers can start near their tested hardness, with Liberty's 2025 range of 8.8 to 21.1 gpg as a guide. Then adjust: if spots come back, raise the setting; if you're using lots of salt with no spots, test again.
Does Goodyear restrict water softeners?
We found no city ban. In 2011, testimony to an Arizona legislative committee named Goodyear among places where HOA or developer rules had limited softeners, but that's old and we couldn't confirm any current rule. Arizona has no statewide softener ban. Check your HOA's CC&Rs before you buy.
Why does Goodyear water hardness vary so much?
The city blends groundwater from wells with treated Colorado River water, and its FAQ says hardness varies throughout the city. Its 2022 report showed a range of 4 to 49 gpg. Liberty Utilities, on groundwater, reported 8.8 to 21.1 gpg in 2025. Your tap can sit anywhere in those ranges, so test before sizing.
Is reverse osmosis worth it in Goodyear?
It's a common add-on for drinking water, especially if you soften, since RO reduces sodium and dissolved solids at that tap. Factor in water use: the city's 2025 report says RO units can use up to 5 gallons of water to make 1 gallon. Look for NSF/ANSI 58 certification and ask about efficiency.
