Two Bellemont homes can sit a short drive apart and still be served by completely different water systems. In North Bellemont, the Flagstaff Meadows subdivision gets water and sewer from Utility Source LLC, a private company that draws from deep wells and runs its own wastewater treatment plant for the subdivision. South Bellemont properties, according to Coconino County's community assessment, rely on private wells or the small Bellemont Water Company. Their on-site septic systems are "primarily alternative due to shallow soil, clay and rock."
The county's adopted Bellemont Area Plan draws the same line. North Bellemont has a private water and wastewater provider. South Bellemont runs on individual onsite wastewater systems and private wells or a small community water system.
That split decides who pays for water, how the cost behaves over time, and what paperwork shows up at closing. In Flagstaff Meadows, the monthly bill depends on geology and on how many neighbors share the cost. In South Bellemont, the buyer owns the system and the responsibilities that come with it.
| North Bellemont / Flagstaff Meadows | South Bellemont | |
|---|---|---|
| Water | Utility Source LLC, deep wells | Private wells or Bellemont Water Company |
| Wastewater | Utility Source treatment plant | On-site systems, mostly alternative designs |
| Who carries the cost | Shared among utility customers through rates set by the Arizona Corporation Commission | The individual owner |
| What surfaces at sale | Utility account transfer, rate history | Septic transfer inspection and Notice of Transfer |
The septic paperwork starts before the listing does
South Bellemont's friction is the more concrete of the two, so it comes first. Arizona's rules require the seller of a property with an onsite wastewater system to hire a qualified inspector within six months before the transfer. The inspector records the system's physical and operational condition and notes whether it was pumped or serviced, or whether an exception applies. Inspectors have to hold one of the credentials the rule lists, such as a professional, contractor, septage-hauler, or wastewater-operator credential.
Under the Arizona Administrative Code, Title 18, Chapter 9, the process runs in this order:
- The seller hires a qualified inspector, who inspects within six months before transfer.
- Before the transfer, the seller gives the buyer the inspection report and any permitting, operating, and maintenance records available.
- Within 15 calendar days after the transfer, the buyer files the Notice of Transfer with the agency responsible for the system.
In Coconino County, the ADEQ Notice of Transfer form sends owners to Coconino County Community Development, Environmental Quality Services. The county's fee sheet, effective September 2021, lists a $50 transfer-of-ownership fee and a $1,057 permit fee for a residential alternative system. Those are agency fees only. They don't cover hiring the inspector or installing a system.
Alternative systems matter in South Bellemont because the soil leaves little choice. An Arizona homeowner manual published by Mohave County puts a new alternative system at roughly $10,000 to $20,000 or more. That's a statewide ballpark, not a Coconino quote. The figure gives the inspection report its weight. It is the document that tells a buyer how close the system on that lot is to needing work.
Water works the same way. A South Bellemont buyer may be taking on a private well, or service from a company whose current rates are hard to confirm. The Arizona Corporation Commission's docket for Bellemont Water Company shows a rate decision from 2008, a compliance filing in 2019, and an administrative closure in 2025. The county assessment also notes a standpipe at the Pilot Travel Center for water hauling.
North of the line, your neighbors set the price of water
Flagstaff Meadows owners don't have to handle the septic process. They do share a cost structure with everyone else on the system, and the subdivision's history shows how that works.
The Arizona Daily Sun reported that Utility Source first served the subdivision from five shallow wells, which the Arizona Department of Water Resources considered inadequate for future demand. To get the adequate-supply designation it needed, the company drilled four wells more than 2,000 feet down into the Coconino Aquifer. The utility's owner told the paper it had "over $3 million of capital investment just in deep wells."
Those wells were sized for a bigger community than the one that existed. In 2006 rate hearings, the company expected up to 350 more homes from Empire Residential, which owned the third unit of Flagstaff Meadows. Empire filed for bankruptcy in 2008 and left the 61-acre parcel with partly finished utilities and no homes. That left the system with about 330 customers. The Daily Sun described the result as a "zombie" subdivision and wrote that residents were bearing "costs that were meant to be shared over a much bigger base."
"On several occasions, I have stated publicly that unless the community grows with new customers, utility rates could double."
The owner gave that testimony to the Arizona Corporation Commission, as reported by the Daily Sun. The prediction held. ACC Decision 75353, dated December 17, 2015, approved increases for both water and wastewater. The Daily Sun reported the typical monthly bill would rise from $55.74 to $121.44 over three years.
The rate schedule from that case shows how much of the bill is fixed. For a 3/4-inch meter, the water side carried a $27.30 monthly charge plus $10 per 1,000 gallons. The wastewater schedule listed a flat $65 monthly charge for the same meter size, with no usage charge at all. A household that cuts its water use lowers only part of the bill. The rest pays for wells and a treatment plant that cost the same to run however many homes share them.
These figures are historical. The Commission warns that its posted tariffs may not be current and points readers to the docket for the latest approved rates. The Utility Source rate docket lists filings through October 2, 2026, all labeled as compliance with Decision 75353 rather than a new rate application. The company's website doesn't post rates and asks customers to call to start service.
The system has grown, and more may come
The Unit 3 stall didn't last. In a Daily Sun story about 2017 pricing, Capstone Homes was building Flagstaff Meadows homes, with about 240 planned and three models starting below $300,000. Capstone built "net zero ready" homes rated between 49 and 55 on the HERS index, and planned a second phase connecting the first with the existing townhomes. The Department of Energy lists Capstone as the builder of a Flagstaff Meadows model home in its 2018 program year.
By the county's assessment, updated February 2025, Utility Source had 640 connections. During the rate case, the Daily Sun counted roughly 330 customers. Connections and customers aren't measured the same way, so the two numbers don't line up exactly, but the system is clearly larger than it was when the deep wells were being paid for. How much of that growth shows up in today's bills depends on the current tariff, which couldn't be confirmed for this post.
The next possible addition is Shadow Mountain Wells. On May 19, 2026, the Coconino County Board of Supervisors voted 5-0 to approve a preliminary plat for 80 duplex lots on 11.2 acres north of W. Brannigan Park Road, just west of the Pilot Travel Center. Utility Source is one of the applicants. The county's Planning and Zoning Commission had recommended approval back on July 28, 2021. The county's resolutions index also lists the same 80-lot plat as "re-recorded," in an entry posted August 5, 2026.
A preliminary plat is a long way from finished homes. Before a final plat can be submitted, the conditions require ADEQ approval of the community water and wastewater systems, Arizona Corporation Commission approval to expand Utility Source's service territory, and a water adequacy report from ADWR. No lot can be sold until the Arizona Department of Real Estate issues a Public Report. The developer also has to submit an updated traffic impact analysis and install whatever improvements the county or ADOT require.
How Arizona's adequacy rule reads outside the Phoenix and Tucson areas
The adequacy report for Shadow Mountain Wells points to a rule that surprises buyers coming from Maricopa or Pima County. Inside Arizona's Active Management Areas, a developer must show an assured 100-year supply before lots can be sold. Bellemont sits outside those areas, in ADWR's Verde planning area. According to ADWR's program overview, the Adequate Water Supply Program outside AMAs requires that adequacy or inadequacy be disclosed in the public report given to first purchasers, and that any water supply limitations be described in promotional or advertising material. Proof of adequacy is required before plat approval only in jurisdictions that have adopted mandatory adequacy.
The Shadow Mountain Wells resolution reflects this. Its final plat has to carry a note stating whether ADWR found the supply "adequate or inadequate" under A.R.S. § 45-108. Under the statute, an adequate supply means water that is continuously, legally, and physically available for at least 100 years, along with a demonstrated financial ability to build the water facilities needed to deliver it.
Utility Source appears on ADWR's list of providers designated as having an adequate supply, current as of September 9, 2026. The list also notes that a new development can use a provider's designation only with a written commitment of service from that provider.
Questions buyers ask about Bellemont water
Can I find out what a Flagstaff Meadows home actually pays for water and sewer? The most reliable source is the seller's recent Utility Source bills, combined with the current approved tariff in the Commission's docket. The 2015-era figures above show how the bill is built. They are not a current quote.
Who handles the septic Notice of Transfer in South Bellemont? Under the state rule, the seller arranges and provides the pre-transfer inspection, and the buyer files the Notice of Transfer within 15 calendar days after the transfer. In Coconino County, that filing goes to Environmental Quality Services.
Does the planned interchange work change any of this? ADOT lists its I-40 Bellemont interchange design concept update as complete and says a preferred alternative was identified. The meeting materials reviewed don't say which alternative was chosen, and none of it affects how water or wastewater service works on either side.
If you're looking at a home in Bellemont, it helps to gather the water records early, whether that means recent utility bills in Flagstaff Meadows or septic inspection and well records south of the interstate.
