"Several of the deep wells that supply water to the Waikoloa community are currently out of service due to equipment malfunctions." That line comes from a notice Hawaii Water posted on September 30, 2026. It asks every Waikoloa customer to cut non-essential water use by 25 percent while 4 of the utility's 8 groundwater wells are repaired.
Anyone comparing Waikoloa Village with Waimea, the resort corridor or Kailua-Kona has already seen the prices. Listings say nothing about where the water comes from. In the Village, water doesn't come from a county department with a large network behind it. It comes from one regulated private company pumping one aquifer through a small group of very deep wells. Every home sits on that same setup. This fall shows what that means for monthly bills, for yards and for how much more housing the community can add.
The September notice is specific. Hawaii Water asks customers to water only between 5 p.m. and 9 a.m. It also asks them to turn irrigation off when it rains and for 48 hours afterward, skip car washing unless necessary, put off pressure washing and fix leaks quickly. The utility expects the advisory to last about two to three months. Counting from the September 30 posting date, that runs to roughly the end of 2026. As of early October the page still said updates would come as repairs progress, and no completion date had been posted.
The reason for the delay matters more than the restrictions. The wells run about 1,300 feet below ground and need specialized pumps. Hawaii Water says the replacement parts "currently have extended manufacturing and delivery timelines, due to ongoing supply chain and production constraints." A broken pump in a system this size can't be fixed with a part from a warehouse in Hilo. Repair time depends on a factory's schedule. Meanwhile the remaining wells carry the whole community.
The utility also says the system "continues to meet current customer needs." The notice mentions no surcharge or penalty. Taps aren't running dry. With so few wells, losing half of them is enough to change how a whole community waters its landscaping.
The Hawaii Public Utilities Commission names West Hawaii Water Company as the potable water provider for Waikoloa Village homes, condominiums and businesses, and West Hawaii Sewer Company as the wastewater provider. Hawaii Water Service is the company behind both the conservation advisory and the latest Waikoloa rate decision. Big Island Now identifies it as a subsidiary of California Water Service Group and reports that it provides wastewater collection and treatment in Waikoloa Village and runs two treatment plants.
All of the utility's potable water comes from eight wells permitted in the Waimea Aquifer, Big Island Now reported in October. Three things follow from that structure, and each one reaches a homeowner differently:
The most recent rate decision took effect October 9, 2025. The PUC approved a $4.7 million annual revenue increase across the five systems in Hawaii Water's Waikoloa service area. The monthly charge on standard 5/8-inch and 3/4-inch meters went from $12.07 to $19.67. On that charge alone, a typical household pays $7.60 more each month.
The timing explains why the jump was so large. The company filed its application in July 2024. The previous general rate increase was approved in January 2019 and phased in over two years. In between, according to California Water Service Group's announcement, the utility invested about $33 million in Waikoloa.
| Category reported by the utility | Approximate investment since 2019 |
|---|---|
| Drinking-water wells, sewer pump stations and backup generators | Nearly $17 million |
| Pipelines | More than $8 million |
| Treatment-plant improvements | Nearly $8 million |
| Total | About $33 million |
Well work is the largest single category of spending, and wells are where the system is under strain this fall. Repairs to deep-well equipment are ongoing capital costs, and under PUC regulation those costs typically come back to customers in a later rate case. One caution: Hawaii Water's August 2026 rate filing covers its North Kona and Kukio systems, not Waikoloa. Our research found no pending Waikoloa rate case.
The aquifer also shapes what can be built in the Village. That came into focus on October 6, 2026. The County Council's Committee on Legislative Approvals and Acquisitions voted 5–3 to give an unfavorable recommendation to Bills 186 and 187. Those bills would allow Waikoloa Green, a proposal for about 400 apartments and 300 single-family homes on 711 acres of former Parker Ranch land south of Waikoloa Road near Paniolo Avenue. Big Island Now reported that water was a leading concern. The full council has yet to hear the bills.
The numbers from the state carried the most weight. According to the Commission on Water Resource Management, the project would draw 1.24 million gallons a day from the Waimea Aquifer System Area, on top of existing withdrawals of 14 million gallons a day.
"This would bring the total daily draw from the Waimea aquifer to 91% of its sustainable yield per day." Ciara W.K. Kahahane, deputy director, Commission on Water Resource Management, as reported by Big Island Now
The developers said Hawaii Water had committed water to the project in a letter dated August 28, 2025. Council Member Rebecca Villegas responded that the developer "is relying on Hawaiʻi Water Service, but they are only capable of estimating how much water they can pump, without knowledge of the water levels in the aquifer." The figures also differ depending on who reports them. West Hawaii Today reported that the applicants first estimated 1.29 million gallons a day, then cut that to 362,000. The baseline they used was a 2019 state estimate of 16 million gallons a day in sustainable yield from the Waimea Aquifer. According to Big Island Now, the state's 1.24 million figure covers the residential units plus the project's agricultural lots and food hub.
Waikoloa Green isn't the only new demand. Na Hale Makoa, a 140-unit workforce rental project at 68-3491 Iwikuamoʻo Drive, was dedicated in May 2026 after residents began moving in during February, West Hawaii Today reported. The county's 2026–27 capital budget includes $11 million for streets plus water and sewer lines serving the 850-unit Kamakoa Nui project, which is slated for completion in 2030. The same paper reported that more than 1,000 new units are planned along the Village's northern edge over the next five years. Neither West Hawaii Today report names a water supplier for Na Hale Makoa or Kamakoa Nui. Both add homes to a Village whose current water supply depends on a utility running on half its wells this fall.
For a buyer, a water system like this affects ownership in a few concrete ways.
The yard. Landscaping in the Village already goes through the Waikoloa Village Association. Its Environmental Control Committee must approve grading, new construction, landscaping and exterior improvements before work starts. Any landscape plan therefore depends on two things, the association's approval process and the utility's supply. A garden that needs heavy irrigation now falls under the 5 p.m. to 9 a.m. window and the request to cut back.
The fixed costs. The WVA payment page lists 2026 annual dues of $1,120. It describes split payments of $560 in January and $570 in July, which add up to $1,130, so it is worth confirming the exact figure with the association. Dues sit alongside a water and sewer bill that is set in Honolulu through PUC proceedings, not locally.
The future bill. The last two Waikoloa rate cases came roughly six years apart and followed major capital spending. That history offers no forecast. It does show that well repairs and new connections tend to end up in what customers pay.
This is general information about how the Village's water and association systems work. It is not legal, tax or financial advice, so please confirm the details of your own situation with the association, the utility or a qualified professional.
Is the conservation advisory permanent? No. Hawaii Water estimated it would last about two to three months from its September 30, 2026 posting while four wells are repaired. As of early October the utility had not posted a repair update.
Does Waikoloa Beach Resort use the same utility? Hawaii Water's October 2025 rate decision covered five systems across its Waikoloa service area, including the Resort and the Village. Its wastewater arm serves condominiums, hotels and businesses at Waikoloa Beach Resort.
Is Waikoloa Green approved? No. On October 6, 2026, a council committee voted 5–3 to give it an unfavorable recommendation. The bills still go to the full council, where amendments are possible.
