Who supplies water to an Apple Valley home?

You’re looking at an Apple Valley home and need to know who supplies its water, what bill to review, and whether the Town’s proposed takeover changes the answer. Start with the address: Liberty Utilities owns the water company at the center of the case, but Apple Valley has multiple water purveyors, so you need to check the address.

The August 24, 2026 California Supreme Court opinion did not approve or prohibit the acquisition. It decided the legal standard for reviewing the proposed taking and returned the case for further proceedings.

This article is educational, not legal or tax advice. For a purchase or rental property, keep the service address, filed tariff and pending court case as separate checks.

Who supplies water to an Apple Valley address?

The supplier depends on the address, so confirm the purveyor before using Liberty’s tariff to estimate a home’s water costs.

Apple Valley Heights County Water District says Apple Valley has more than eleven water purveyors serving its rural communities. Its page says residents of Apple Valley most likely receive Liberty service, but that statement does not establish the supplier for a particular home. The page points to a Water Boundary Tool for confirmation.

Listed purveyors include Golden State Water Company, Mariana Ranchos County Water District, Apple Valley Foothill County Water District and Liberty Utilities. A Town address alone isn’t enough to choose among them.

Record the supplier identified for the property before comparing service charges or rental billing terms. The address question also appears in Hemet’s water provider split; use the Apple Valley district’s information for the Apple Valley property you’re checking.

We were helping an Apple Valley buyer compare two homes when he noticed that their water information was different. He assumed one company served the entire town and wanted to use the first home’s bill to estimate costs for the second. We checked each address separately because the water provider can depend on where the property is located.

Why is the Town trying to acquire the water system?

The Town began considering public ownership after the system’s then-owner was sold to an investment fund that implemented significant price increases.

The California Supreme Court opinion traces that sale to December 2010. Liberty later acquired the water company from the fund. The opinion gives no figure for those earlier increases.

In November 2015, the Town approved two resolutions of necessity. One covered the system within Town boundaries; the other covered small portions outside those boundaries. Their project description was “the public ownership, operation and maintenance of the Apple Valley Water System to provide water service to the public.”

The Town then filed an eminent domain complaint in San Bernardino County Superior Court, case CIVDS1600180. That history explains the proposed acquisition’s origin. It doesn’t establish what public ownership would cost customers or whether the Town will acquire the system.

What did the Supreme Court decide?

The Supreme Court decided that the trial court must exercise independent judgment when reviewing the utility owner’s challenge to this proposed taking.

After a 67-day bench trial, the trial court found that the Town lacked the right to acquire the system and entered judgment for Liberty. The Court of Appeal reversed, saying the trial court should have applied a “gross abuse of discretion” standard.

The Supreme Court rejected that approach. Under its decision, the trial court weighs whether the utility owner has rebutted the relevant presumptions and established, by a preponderance of the evidence, that the taking is not authorized by the Eminent Domain Law.

The background rule matters: since 1992, a resolution of necessity for taking a privately owned electric, gas or water public utility creates a rebuttable presumption that statutory requirements are met. It isn’t conclusive proof.

The Supreme Court reversed the Court of Appeal and remanded for further proceedings consistent with its opinion.

Is the proposed takeover settled?

The proposed takeover remains unresolved; the Supreme Court opinion neither authorizes nor prohibits the acquisition.

As of 30 October 2026, the proposed acquisition remains subject to further proceedings following the August 24 opinion. The eventual outcome and the Court of Appeal’s timetable are not established by the cited sources.

One unresolved issue concerns evidence arising after the resolutions of necessity. Liberty raised that issue, but the Supreme Court left it for the Court of Appeal to address first. Other issues also remain for that court.

The Town’s August 24 press release says the Town and its legal team are reviewing the opinion and evaluating next steps. It doesn’t announce a change to customer service or discuss water rates.

For your property review, the ruling supplies legal context. It does not supply a new water bill, a transfer date or a basis for predicting future charges.

Which tariff should a buyer review?

A buyer should first confirm the purveyor, then check that supplier’s current filed tariff for the service being evaluated.

For Liberty’s system, the cited document is Schedule No. 1, Residential General Metered Service. Liberty’s tariff territory is the Town of Apple Valley and vicinity, the Town of Yermo and vicinity, in San Bernardino County. That territory description doesn’t replace an address check.

Keep those documents with your property review. For another ownership-focused water topic, see Fallbrook’s water bill and a new owner.

What does the cited residential rate sheet show?

The sheet effective July 1, 2025 shows a monthly service charge plus quantity charges, with additional tariff conditions affecting bills.

For a 5/8 x 3/4-inch meter, that sheet lists a monthly service charge of $37.90. It calls this a “readiness-to-serve charge,” added to the quantity charge.

The quantity charges are expressed per 100 cubic feet:

• The first 6 units are charged at $3.414 each.
• Units 7 through 26 are charged at $4.552 each.
• Units over 26 are charged at $7.876 each.

The sheet also provides for a late charge under Schedule LC and says all bills are subject to the California Public Utilities Commission reimbursement fee under Schedule UF.

These are figures from the sheet effective July 1, 2025, not a statement of today’s rates. The utility is regulated by the Commission, and its tariff uses numbered sheets and Advice Letter filings.

The tariff Table of Contents, effective June 1, 2026, still lists Sheet 1265-W for Schedule No. 1. Check the current tariff before calculating an expected bill.

Can a tenant’s unpaid bill affect the landlord?

A tenant’s unpaid bill can affect how Liberty furnishes service to subsequent tenants under Schedule No. 1’s special condition 2.

The condition addresses a tenant who leaves a rental unit owing the company. In accordance with Section 2714 of the Public Utilities Code, service to subsequent tenants in that unit may, at the company’s option, be furnished on the landlord’s or property owner’s account.

That wording matters for a rental purchase. It identifies an option concerning the account used for subsequent service. Read the actual condition when assessing landlord responsibility rather than assuming the next tenant’s service will always remain on a separate account.

The filed tariff is the document to review for this provision; the Supreme Court’s decision does not answer the rental account question. If you’re also sorting out other property utility charges, Loma Linda’s water, sewer and trash billing article is a separate Learn reference.

The short version

Confirm the water supplier for the address, review its current tariff, and treat the Town’s proposed acquisition as unresolved.

Liberty isn’t the only purveyor listed for Apple Valley. Its cited residential sheet separates the monthly meter charge from water usage charges and includes a condition affecting service after a tenant leaves owing the company.

The Supreme Court settled the standard of judicial review. It didn’t settle ownership of the system or announce a customer rate change. Keep the pending case separate from the documents you use to assess the property’s water service and rental billing exposure.
