If you're comparing Waikoloa Village to a home near Waimea or along the Kohala Coast, the number most buyers pull up first is the median sale price. The number that actually shapes your monthly costs over the next several years arrived quietly last October, when the base water charge on a standard household meter rose from $12.07 to $19.67. That's a 47.89 percent increase, and it tells you more about the real cost of living in the Village than any single month's list price does.
One Utility, One Aquifer
Much of Kailua-Kona and parts of Waimea get their water from the county Department of Water Supply. Waikoloa Village doesn't. Water there comes from wells operated by Hawaii Water Service, a private utility owned by California Water Service Group, a company traded on the New York Stock Exchange under the ticker CWT. There's no second provider to call if you don't like the rate. When Hawaii Water Service wants to raise what it charges, it files a general rate case with the state Public Utilities Commission, a process that moves slowly and lands as one lump adjustment rather than a series of small annual bumps.
The most recent case took longer than most. Hawaii Water Service filed for the increase in July 2024. The commission didn't issue its decision until October 2025, and that ruling covered five systems across the Waikoloa service area, together approved for $4.7 million in additional annual revenue. The change residential customers actually felt is the one on their bill: the base rate for a 5/8-inch or 3/4-inch meter, the size on nearly every single-family lot in the Village, went up 47.89 percent effective October 9, 2025.
That increase followed a six-year gap. The utility's last general rate case was approved in January 2019 and phased in over two years. Owners who bought in 2020 or 2021 had gotten used to a flat number on their water bill. Last fall reset that.
| What changed | When | Detail |
|---|---|---|
| Base water rate, 5/8" and 3/4" meters | Effective Oct. 9, 2025 | Rose from $12.07 to $19.67 per month, a 47.89% increase |
| Total revenue increase, five Waikoloa systems | PUC decision, Oct. 2025 | $4.7 million annually |
| Prior general rate case | Approved Jan. 2019 | Phased in over two years |
| Capital investment since 2019 | 2019 through the 2025 filing | About $33 million, including nearly $17 million for wells, sewer pump stations, and backup generators |
None of this makes Waikoloa Village a bad place to buy. It means the water bill is a line item that moves in large, infrequent steps rather than small, predictable ones, and the next step is a matter of when, not if.
Why the Wells Cost What They Cost
The capital spending behind that rate case is specific. Hawaii Water Service has put roughly $33 million into its Waikoloa systems since 2019, with close to $17 million of that going toward drinking water wells, sewer pump station upgrades, and backup power generators meant to keep water flowing during outages. That's the kind of infrastructure that doesn't show up when you tour a house, but it's baked into what you'll pay every month to live there.
The deeper reason the utility keeps investing in wells rather than just raising prices on the existing ones comes down to what's actually underground. Waikoloa Village and the Waikoloa resort area both draw from the Waimea aquifer, and according to the state's own Water Resource Protection Plan, that aquifer has the smallest sustainable yield of any aquifer sector on Hawai'i Island, estimated at just 16 million gallons a day. Wells already permitted in that aquifer could legally draw up to 29.75 million gallons a day if pumped to capacity, which is 172 percent of what the aquifer can sustainably provide. Actual reported pumping has stayed well below that ceiling, running around 14.35 million gallons a day as a 12-month average through April 2026, or about 89.68 percent of sustainable yield. Hawaii Water Service's own wells account for roughly 5.8 million gallons of that daily draw, serving both the Village and the resort.
That margin is thin enough that new development matters. A project called Nani Kai, on the Village's northern edge, has already won county approval for its first phase of 78 luxury home sites. If the rest of the project is approved, another 1,672 home sites beyond that first phase, it alone could add more than a million gallons a day to demand on the same aquifer. None of this means the tap is about to run dry. It does mean the rate increases aren't a one-time correction. They're a structural feature of buying into a community whose water source has limited room to grow alongside it.
The Median Price Moves More Than the Market Does
Water isn't the only number that behaves differently in the Village than it does elsewhere on the coast. The median sale price does too, and for a related but separate reason: not enough homes sell there in any given month for the median to hold steady.
In November 2025, only seven homes sold in Waikoloa Village. The median price that month was $730,000, up 46 percent from the same month a year earlier, and homes were taking an average of 147 days to sell compared with 90 days the year before. By July 2026, the trailing 12-month median had settled to $753,373, up a much calmer 10.8 percent year over year. A separate tracking service showed the broader Waikoloa area, which blends Village and resort listings, at a median list price of $899,000 in January 2026 with an average sale price of $937,512, while that same source's trailing 12-month median sale price ran lower, at $802,500, down 8 percent from the prior period.
None of those figures are wrong. They're measuring different windows in a market thin enough that one high-end closing can swing a monthly median more than an entire year of renovation trends or buyer demand would. That's not a fee hiding in a bill. It's a sample size dressed up as a market signal, and it's worth knowing before you decide a single month's number tells you where prices are actually headed.
Before You Make an Offer in the Village
A few habits make both of these mechanics easier to see through:
- Ask the seller for the last 12 months of actual water and sewer bills, not just the current rate sheet. Bills show usage patterns a rate table can't.
- Confirm the meter size on the property and whether irrigation runs through a separate meter, since that affects which rate line applies.
- Check the Hawaii Public Utilities Commission's docket list for any pending rate case before you assume the current price is fixed for the next several years.
- Request 6 to 12 months of comparable sales rather than relying on the most recent single month's median. In a market this thin, one closing changes the story.
- If you're weighing a Village home against one on county water in Kailua-Kona or Waimea, ask your lender and insurer how the two systems are treated differently in underwriting.
Waikoloa Village remains one of the more livable, unpretentious corners of the Kohala foothills, cooler and quieter than the coast, with a strong sense of neighborhood. Understanding how its water utility and its sales data actually work doesn't take anything away from that. It just means you're deciding on real numbers instead of a headline price.
If you're comparing a Village purchase against something along the coast or up in Waimea, I'm happy to pull the actual utility history and a rolling comp set together so you're working from facts rather than a single month's snapshot.
