1.Who Supplies Water at a Queen Creek Address
There are only three answers, and which one applies depends on where the meter sits, not on the mailing city: the Town of Queen Creek Water Division, the Town-operated Diversified Water Service Area, or EPCOR. To settle it for one property, call the Town’s Utilities Department at 480-358-3450 with the street address, Monday through Thursday, 7 a.m. to 6 p.m. A “Queen Creek, AZ” postal address is no proof of Town water service — background on why sits with the ZIP codes carrying a Queen Creek address and which county the parcel is in.
| Provider | What it is | Where it serves | Rate structure |
|---|---|---|---|
| Town of Queen Creek Water Division | Municipal utility run by the Town | Most of incorporated Queen Creek | Tiered; 15% increase approved July 16, 2025 |
| Diversified Water Service Area | Town-operated since Oct. 2, 2020, on its legacy schedule | East San Tan Valley, outside Queen Creek town limits | Flat $3.65 per 1,000 gal; not part of the 2025 increase |
| EPCOR, San Tan Water and Wastewater | Private utility; the ACC named it interim operator of Johnson Utilities in summer 2018, and EPCOR completed the purchase Jan. 29, 2021 | Parts of Queen Creek, San Tan Valley and Anthem in Florence | EPCOR’s own schedule, not the Town’s |
| H2O, Inc. | Historical only; Council approved buying it June 19, 2013 | Folded into the Town system | Not a separate provider |
The Town’s Resident Resources page still carries a note about addresses “receiving water service from H2O, Inc.” getting a separate trash bill, as published in September 2026. H2O stopped being an independent water utility after voters approved the purchase 2,550 to 379 and the Council signed off on June 19, 2013. A listing sheet that puts a Queen Creek home on H2O water is more than a decade out of date.
The Town and EPCOR also traded territory. The Arizona Corporation Commission approved a service-area exchange on Dec. 6, 2022, and on July 1, 2023 the Town became the sole wastewater provider for Encanterra, Ironwood Crossing, the Germann 516/PRI property and a commercial pocket near Ironwood Medical Center. Undeveloped Bella Vista Farms North went to EPCOR. The Town stated that “no current Queen Creek water customers are being transferred to EPCOR.”
The Town’s water service area has nearly doubled in 15 years, from 36 to 69 square miles, and the Town credits acquiring the H2O, Inc. system in 2013 and Diversified in 2020 more than new subdivisions.
2.Where Queen Creek Gets Its Water
The Town’s 2025 Annual Water Quality Report describes the supply as “recovered surface water and groundwater,” pumped from “29 active drinking water wells located throughout the water distribution system,” with a small amount of chlorine added at entry points. That is the day-to-day answer; the longer one is a portfolio assembled deal by deal. August 2019 is when the Town’s first Colorado River transfer was proposed, not bought: the Town announced a $24 million payment and began receiving that water in 2023, and the Harquahala purchases came in 2025.
| Source | What the Town says about it | As of |
|---|---|---|
| Local groundwater, 29 active wells | The Town says the Harquahala purchases bring its portfolio to “90% drought-proof and only 6% reliant on local groundwater pumping”; its own characterization, not a measurement of today’s mix | Town release, May 29, 2026 |
| Colorado River | “Minimal reliance… approximately 10%” of supply | Town water-future page, Sept. 2026 |
| Harquahala Valley groundwater | The Town totals two 2025 purchases at 1.7 million acre-feet, to move on the existing CAP canal; it says it approved funding the larger one in late 2025 and sold the financing in January 2026 | Town water-future page, Sept. 2026; Town release, May 29, 2026 |
| GSC Farm / Cibola entitlement | 2,033.01 acre-feet a year of Colorado River water, flowing since 2023 | ADWR recommendation, Sept. 4, 2020; Town, July 2023 |
| Recovered effluent | Fills park and private-development lakes instead of potable groundwater | Town water FAQ, Sept. 2026 |
Two caveats. The Town publishes those two percentages but no full split of the rest of the portfolio, so any tidy pie chart of Queen Creek water sources fills in blanks the Town has left blank. And an acre-foot, the unit every deal is written in, is defined by the Town as 325,851 gallons, “about enough to serve three homes annually.”
The reuse side is visible if you go looking. The lakes at Mansel Carter Oasis Park and Frontier Family Park, along with several private developments, are filled with recovered and recharged treated effluent rather than drinking-quality groundwater — the Town says so on its own water FAQ.
3.What Queen Creek Bought: the Cibola Transfer and Two Harquahala Deals
Queen Creek went out and bought water. The Town calls the GSC Farm transfer “the first Colorado River to Central Arizona transfer in 50 years” and the Harquahala move “the first designated basin transfer outside the Phoenix Active Management Area.” The deals are separate and at different stages.
| Deal | What it secures | Price | Status |
|---|---|---|---|
| GSC Farm / Cibola entitlement | 2,033.01 acre-feet a year, in perpetuity (2,083.1 af originally proposed in 2019) | One-time $24 million | Flowing since 2023; federal environmental review still under way at the Town’s October 2025 update |
| ADWR Harquahala transportation determination | Up to 5,000 acre-feet a year for up to 110 years, capped at 500,000 acre-feet total | A determination, not a purchase | Granted July 18, 2025 on a Feb. 28, 2024 application |
| First Harquahala purchase, May 2025 | 500,000 acre-feet | $38.6 million | Reported by the Queen Creek Tribune — secondary |
| Second, larger Harquahala purchase, late 2025 | 1.2 million acre-feet, capped at 12,000 acre-feet a year | $244.4 million: certificates of participation sold January 15, 2026, 40-year term at 4.9%, annual debt service $12.1 to $14.8 million; a $90 million WIFA loan at 3.9% over 30 years, first two years interest only, replaces part of them | Approved and funded in late 2025 per the Town, financed January 2026; no delivery date published |
The “1.7 million acre-feet” headline on the Town’s water-future page is the Town’s own total for its two 2025 Harquahala purchases. The Town’s release of May 29, 2026 states that “in late 2025, the Town approved funding an additional 1.2-million-acre feet of water for $244.4 million,” paid for with certificates of participation sold on January 15, 2026 over a 40-year term at 4.9%, carrying annual debt service of $12.1 to $14.8 million; a $90 million WIFA loan at 3.9% over 30 years, the first two years interest only, replaces part of that borrowing. The Town dates the approval only to “late 2025” and publishes no day for it. The Town also says the combined purchases bring its portfolio to “90% drought-proof and only 6% reliant on local groundwater pumping,” which is the Town’s characterization of its own portfolio. Approved and financed is not the same as delivered: no Town source published as of September 2026 says this water is flowing yet.
The Cibola side has an open question too. Western Arizona municipalities sued the U.S. Bureau of Reclamation — not Queen Creek — and an Environmental Impact Statement was still running as of the Town’s October 2025 update, with the court allowing deliveries to continue meanwhile. Town Director of Water Resources Paul Gardner put the transfer’s 100-year value at “nearly 365,000 acre feet” with reuse, in July 2023.
None of this arrives in a new canal. Harquahala water moves on the existing CAP canal, which the Town describes as running north of the Harquahala Valley and past Queen Creek’s eastern border.
4.Does Queen Creek Have a 100-Year Assured Water Supply?
Yes for current customers, not yet for the Town as an institution, and the two are not the same claim. The Town’s FAQ states that “all current Town of Queen Creek residential water customers have a certificate of 100-year assured water supply through groundwater.” The Town itself is not an ADWR Designated Water Provider; as of a July 2023 statement it was “working toward becoming a designated provider by 2030.”
What bridges the gap is CAGRD membership. 89% of Queen Creek water customers are assessed a Central Arizona Groundwater Replenishment District fee on their property tax bill; the remaining 11% or so are exempt from the Arizona Groundwater Management Act. CAGRD is not a separate agency but “a special function of Central Arizona Project,” and the line item rides on the same bill as the rest of your Queen Creek property taxes.
The unresolved part sits on the development side. Roughly 10,000 platted or approved single-family homes carry no certificate of assured water supply and cannot be built until a renewable source is secured for them, on the Town’s FAQ as published in September 2026, following the state’s 2023 Phoenix-area groundwater findings. That constrains future subdivisions, not water already coming out of a tap.
The short version for a buyer: an existing Queen Creek home on Town water has a 100-year assured water supply certificate today; a raw lot may not. Ask the Utilities Department at 480-358-3450 which category a specific parcel falls into before signing anything on undeveloped land.
5.Is Arizona in a Water Shortage, and Does It Reach Queen Creek?
Arizona is in a shortage; the local figure to hold on to is that the Town puts its own Colorado River reliance at “minimal… approximately 10%” of supply, on its water-future page as published in September 2026. The Town does not publish a percentage for the rest of the portfolio, and neither the Town nor the Central Arizona Project publishes a Queen Creek-specific effect from the 2026 reduction — so this page states the statewide numbers and the Town’s share, and stops there rather than estimating one.
The statewide arithmetic is CAP’s. Arizona is taking Tier 1 Colorado River reductions for 2026, and CAP puts the cut at 512,000 acre-feet — 30% of CAP’s normal supply, about 18% of Arizona’s Colorado River supply and just under 8% of Arizona’s total water use. Nearly all of the reduction falls on CAP water users, and mostly on agricultural ones.
Locally, the Town completed a 3-million-gallon storage facility in 2020 and has two more under construction as of September 2026. It credits its Waterfluence partnership with HOAs with saving “more than 47 million gallons” in the most recent year cited, though it does not date that figure.
6.What Queen Creek Water Actually Costs
Council approved a 15% water rate increase on July 16, 2025 — the first residential rate adjustment in more than 15 years — worth “$3-$6 per month for most residential customers.” The Town’s page gives two effective dates: the top says Aug. 27, 2025, the Next Steps section says “beginning with the Oct. 7 billing cycle.” It never reconciles them, so read it as approved in July 2025 and on bills by that fall.
| Meter size | Monthly minimum, includes the first 1,000 gallons |
|---|---|
| 3/4 inch | $21.08 |
| 1 inch | $35.65 |
| 1.5 inch | $52.90 |
| 2 inch | $88.55 |
| 3 inch | $211.60 |
| 4 inch | $350.75 |
| 6 inch | $1,546.75 |
| Charge | Town of Queen Creek | Diversified Water Service Area |
|---|---|---|
| 1,001 – 10,000 gallons | $2.04 per 1,000 gal | $3.65 per 1,000 gal, flat |
| 10,001 – 20,000 gallons | $2.73 per 1,000 gal | $3.65 per 1,000 gal, flat |
| 20,001 gallons and above | $3.40 per 1,000 gal | $3.65 per 1,000 gal, flat |
| 3/4-inch monthly minimum | $21.08 | $27.50 |
A worked example: 10,000 gallons a month on a 3/4-inch meter
Water alone is $39.44 a month at 10,000 gallons on a 3/4-inch meter. That is the figure to compare against another town, because it depends only on the meter and the month’s use. Sewer and trash ride the same Town bill, but the sewer half turns on a number the water half does not: the household’s average winter water use.
- Water delivery: the $21.08 minimum covers the first 1,000 gallons, then 9,000 gallons at $2.04 per 1,000 adds $18.36. Subtotal $39.44.
- Sewer: a $10.25 residential base plus $4.82 per 1,000 gallons, billed on 70% of average winter water use — not on this month’s use. Only if the winter average is also 10,000 gallons does that come to 7,000 billed gallons, or $33.74, for a $43.99 sewer line.
- Trash and recycling: $16.22 a month as a Waste Connections of Arizona line item on the Town bill, as listed on the Town’s Resident Resources page in September 2026.
- Running total: $99.65 before tax, and only on that same 10,000-gallon winter average. A household with a lower winter average pays the same $39.44 for water and less for sewer, so the combined figure falls. Water charges are then subject to Arizona state and local sales tax plus the Arizona Water Use Tax.
The residential sewer charge is capped at $67.61 a month, a cap tied to 17,000 gallons and in place since July 2021. Because sewer volume is averaged off winter water use, a Queen Creek summer of heavy irrigation inflates the water half of the bill without dragging the sewer half up with it.
7.The Proposed Water Resource Fee and What It Replaces
On Sept. 17, 2026 the Town posted a Notice of Intent for a Water Resource Fee, proposed at $3.07 per 1,000 gallons in Year 1, that would replace the CAGRD assessment now riding on roughly 89% of customers’ property tax bills. It is not adopted. A public hearing with possible Council action is set for Wednesday, Nov. 18, 2026 at 6:30 p.m. in the Community Chambers, 20727 E. Civic Parkway.
| Item | As proposed |
|---|---|
| Year 1 rate | $3.07 per 1,000 gallons |
| Gross monthly impact at 10,000 gallons | $30.70 |
| After the residential and schools wastewater credit (40%) | $18.42 |
| Commercial or multifamily with landscaping | 80% credit |
| Commercial or multifamily without landscaping | 90% credit |
| Earliest effective date | January 2027 for the non-capacity fees, first appearing on bills in March 2027 |
The package proposes more than the fee. Single-family tiers 1 and 2 would fall while tier 3 rises; multifamily moves to a uniform $1.50 per 1,000 gallons plus base, non-residential to $2.50, landscape to $4, hydrant to $9. Solid waste would rise $3.78 a month for every curbside customer, and one-time capacity fees would be added for new development. All of it awaits the Nov. 18, 2026 hearing, so build the range rather than the specifics into a Queen Creek cost-of-living estimate.
The Town’s own “Securing Queen Creek’s Water Future” page gives two different figures for what paying CAGRD at the maximum allowable rate since 2018 has saved customers: $71 million in the main section and approximately $58 million in the FAQ further down the same page, both as published in September 2026. The Town does not reconcile them. Cite either one with that caveat attached.
8.Water Quality, Hardness and the Softener Question
Queen Creek tap water is hard: 6 to 17 grains per gallon town-wide, per the Town’s water FAQ. Fluoride is naturally occurring rather than added: the Town’s FAQ gives 0.4 to 0.6 parts per million, which the 2025 report corroborates rather than repeats — the report’s own measured range is non-detect to 0.70 ppm, average 0.55 ppm. Whether hardness justifies a softener is a household call; 6 to 17 grains is the number to price against.
On contaminants, the 2025 report records no violations for anything tested — arsenic, barium, chlorine, chromium, combined radium, fluoride, gross alpha, nitrate, sodium, total coliform, TTHMs, uranium, lead, copper, PFAS and lithium are all listed “No” under Violation. The Town also reported no lead or galvanized service lines requiring replacement, and obtained a lead-free validation waiver from ADEQ, “one of the first municipalities to do so.”
The report is published in English and Spanish and linked from the Town’s water quality page; quality questions go to 480-358-3459. The Town also brought annual sampling in house rather than hiring vendors, which it estimates saves $60,000 to $95,000 a year.
There is no published mandatory watering-restriction stage in Queen Creek. The conservation programs the Town publishes are voluntary and incentive-based — turf-conversion rebates, free classes, the Waterfluence HOA partnership and a leak-check tool — and the conservation line is 480-358-3455.
9.A Queen Creek Water Checklist Before You Close
- Confirm the provider by street address, not mailing city. The Town, the Town-run Diversified area and EPCOR all serve addresses reading “Queen Creek,” on three rate schedules.
- Ask which meter size serves the house. A 3/4-inch meter carries a $21.08 monthly minimum that covers the first 1,000 gallons; a 1-inch meter carries $35.65, whether the house uses the water or not.
- Ask whether a CAGRD assessment appears on the property tax bill. About 89% of customers pay it there today, and the proposed Water Resource Fee would move that cost onto the water bill.
- On a vacant lot, ask the Utilities Department whether the parcel holds a certificate of assured water supply. Roughly 10,000 platted single-family homes in town do not.
- Price hard-water treatment, or the maintenance it prevents: hardness runs 6 to 17 grains per gallon.
- Read the current Annual Water Quality Report, not a third-party rating site. The 2025 edition lists every tested contaminant with its violation status.
Water is only one of the things that changes at the town line. The Queen Creek and San Tan Valley comparison sets out the rest, from taxes to schools.
