How much does Folsom Lake water cost by the time it reaches an Orangevale faucet? That depends on which side of a service boundary the house sits on. The boundary isn't marked on any listing photo, and you won't find it in a property description either.
Orangevale has three retail water providers. Orange Vale Water Company covers the center of town, Citrus Heights Water District serves other parts, and Fair Oaks Water District reaches into the western edge. Each one buys its water wholesale from San Juan Water District, whose supply is stored in or passes through Folsom Lake. Their retail rates are built very differently, though, and on a large irrigated lot the gap between two neighbors' bills can add up to real money over a year.
For a buyer comparing Orangevale homes, the water provider is one of the few ongoing costs that is set by the parcel itself, so it's worth checking.
A boundary drawn in 1896
Orange Vale Water Company is the oldest piece of this. It filed articles of incorporation on May 29, 1896, and it is a mutual water company. That means it is owned and run by its consumers, not by a public agency. In 1994 it adopted California's Non-Profit Mutual Benefit Corporation Law, and its shareholders became members. Its own history page lists 4,486 members holding 5,159 shares. A five-member board, elected to two-year terms, governs the company from its office at 9031 Central Avenue.
The company describes its territory as roughly 3,075 acres. It runs from about Kenneth Avenue on the west to where Madison Avenue and Greenback Lane merge on the east, and from Pershing Avenue on the south to Oak Avenue on the north. It serves about 5,500 connections, including small pieces of Fair Oaks and Folsom. Homes outside that area may be on Citrus Heights Water District or, toward the west, Fair Oaks Water District.
Those lines trace back to the town's colony-era beginnings, and no one redraws them when a house sells. The provider comes with the parcel.
Every provider pays the same wholesale price
All three retailers buy from San Juan Water District at the same volumetric price. San Juan's Calendar Year 2026 schedule lists wholesale water usage at $58.39 per acre-foot, effective January 1, 2026. An acre-foot is about 435.6 hundred cubic feet, the unit all three retailers use on their bills. So the water itself costs each of them roughly 13 or 14 cents per unit.
Orange Vale Water Company even names the plant its water comes through. The supply is delivered by gravity through the Sidney N. Petersen Treatment Plant, straight from Folsom Reservoir. Citrus Heights Water District and Fair Oaks Water District also add groundwater from their own wells.
The retail prices each district charges for a unit of water are shown below. The difference between those prices and the wholesale price pays for each retailer's pipes, meters, wells, staff, and capital programs.
| Provider | How it bills | Fixed charge, smallest residential meter | Per unit of water | Other recurring charges |
|---|---|---|---|---|
| Orange Vale Water Company | Monthly | $26.60, meters up to 1 inch | $0.90 | $15 a month capital improvements assessment |
| Citrus Heights Water District | Every two months | $71.57 for ¾-inch, $128.00 for 1-inch | $1.38 | Project 2030 charge of $6.90 or $17.25 |
| Fair Oaks Water District | Every two months | $90.98 for 1-inch | $0.64 | None listed |
The Citrus Heights and Fair Oaks figures come from each district's 2026 schedule. Orange Vale Water Company's posted schedule is labeled "Effective April 1, 2024," and the company notes that rates can change with board approval. Treat that column as the published schedule, and confirm the current numbers with the company.
None of the three uses tiered pricing. Each charges one flat price per unit no matter how much a household uses.
The same household under each provider's rates
To compare them, take one home with a 1-inch meter and run the published rates over the same two-month billing period. The first column is 60 units of use. The second is 120 units, closer to what a summer of lawn, garden, and orchard watering on a big lot might use. These are calculations from the posted rates, not quotes from the providers.
| Provider and meter | 60 units over two months | 120 units over two months |
|---|---|---|
| Fair Oaks Water District, 1-inch | $129.38 | $167.78 |
| Orange Vale Water Company, up to 1-inch, 2024 schedule | $137.20 | $191.20 |
| Citrus Heights Water District, ¾-inch | $161.27 | $244.07 |
| Citrus Heights Water District, 1-inch | $228.05 | $310.85 |
The water itself, at San Juan's wholesale price, makes up about $8 of the 60-unit bill. Fixed charges make up most of the rest. At 60 units, fixed charges are about 70 percent of the Fair Oaks bill, about 61 percent of the Orange Vale bill, and about 64 percent of a 1-inch Citrus Heights bill.
With fixed charges that large, a household can't change much of its bill by cutting back. Shorter showers barely move it. What sets the floor is the provider and the meter size, and both come with the house.
Meter size and acreage are the levers on big lots
Orangevale has many lots large enough to have horse pastures, fruit trees, and long lawns. On those properties, two details carry extra weight.
Meter size. Each retailer sets its fixed charge by meter diameter, and the charges climb quickly. Citrus Heights Water District charges $222.05 every two months for a 1½-inch meter, plus $34.50 for Project 2030. That's well above the ¾-inch total. Fair Oaks Water District charges $166.74 for a 1½-inch meter. Orange Vale's posted monthly charge goes from $26.60 at up to 1 inch to $56.50 at 1½ inches. A rural property that someone fitted with a larger meter years ago carries that fixed cost for whoever owns it next.
Acreage. Orange Vale's capital improvements assessment is $15 a month for lots up to 5 acres, plus another $15 for each additional 5 acres or part of 5 acres. Most residential lots fall in the first bracket, but a larger parcel inside the company's boundary pays the assessment more than once.
Volume. Heavy use magnifies the gap in per-unit prices. Going from 60 to 120 units adds $38.40 to the Fair Oaks bill, $54.00 to the Orange Vale bill, and $82.80 to the Citrus Heights bill.
How long these numbers are likely to hold
Rate stability differs among the three as well, which matters to a buyer planning a few years ahead.
Citrus Heights Water District announced in May 2026 that its board voted not to raise rates for the rest of 2026 or any of 2027. That holds its current schedule through the end of next year. Fair Oaks Water District adopted its current fees and charges on November 17, 2025, and its three-year rate schedule shows a 0 percent adjustment for 2026. San Juan's 2026 schedule shows Orange Vale Water Company's wholesale fixed charge was last adjusted January 1, 2025, a year earlier than the fixed charges for the two districts. Orange Vale updated its Rules and Regulations on September 14, 2026. Its board meets again on November 3 and December 1, and those meetings are where any rate change would come up.
Citrus Heights Water District notes on its schedule that its rates include automatic adjustments when San Juan raises wholesale charges. Anything that happens at San Juan affects all three retailers, because all three buy from the same source.
Checking a specific address before you write an offer
The provider shows up on the first water bill. For a buyer, it's better to know before writing an offer.
- Search the address or parcel number in Sacramento County's Find My Water Company tool, click the result, and open "Service Districts."
- Ask the seller for recent water bills. They show the meter size and real usage across seasons, which the rate sheets can't tell you.
- Look the provider up on the current rate sheet: Orange Vale Water Company, Citrus Heights Water District, or Fair Oaks Water District.
- If the home is served by Orange Vale Water Company, plan for service setup. Its Rules and Regulations require each new owner of record to apply for water use and keep the company informed of ownership and billing changes.
Water is one of several costs that come with an address, much like the special tax differences covered in our look at what The Parkway's median price leaves out. Our Orangevale neighborhood page has more about the area.
A few quick questions
Is the water quality different between providers? The surface supply comes from the same place. San Juan wholesales Folsom Lake water to all three, and the two districts also pump groundwater from their own wells. Each provider publishes its own reports for anyone who wants details.
Can a homeowner switch providers? Service follows the parcel's location within each provider's service area. None of the three providers' published materials describe a way to choose a different one.
Why does Orange Vale bill monthly when the districts bill every two months? That's how each one has set up its billing. To compare them fairly, double Orange Vale's monthly charges, as the tables above do.
Rates, assessments, and billing rules belong to each provider and can change. This post is general information, not financial or legal advice, so confirm the numbers for a specific property directly with the provider.
