- Upcountry has not accepted new water meter applications since January 1, 2013. If a property does not already have a meter or a place on the list, you cannot simply join the queue.
- About 1,424 applicants were on the Upcountry waitlist as of the January 1, 2026 list.
- The cause is arithmetic. Peak Upcountry demand runs near 10.1 million gallons a day against a maximum supply of about 9.7 million.
- Relief is underway. New treatment filters are expected to lift reliable capacity from 9.7 to about 11.2 million gallons a day.
- Water status is not a detail, it is the deal. On Maui it can determine whether a parcel is buildable at all.
Why water decides Maui land deals
On an island, water is the most contested and most coveted resource there is, and nowhere on Maui is that clearer than Upcountry. I have watched otherwise straightforward transactions turn entirely on whether a parcel had a meter, and I have watched buyers fall in love with land that, functionally, could not be built on in the timeframe they had in mind.
If you are looking at property in Kula, Makawao, Pukalani, Haliimaile or Haiku, water is not a due-diligence footnote. It is the first question.
What is the Upcountry water meter waitlist?
The county’s Upcountry Water System serves Kula, Makawao, Pukalani, Haliimaile, the Maunaolu College area and Haiku. Demand in that system has run ahead of supply for years, and the county’s response was to stop taking new applications.
The Department of Water Supply halted new Upcountry meter applications on January 1, 2013. The existing queue has been working its way down slowly ever since. As of the list dated January 1, 2026, roughly 1,424 applicants were still waiting.
That figure is worth sitting with. It is not a queue you join today and clear next year. For many parcels it is not a queue you can join at all.
Why the backlog exists
The reason is straightforward supply arithmetic rather than bureaucratic obstruction. According to The Maui News reporting on the waitlist, peak Upcountry demand sits at roughly 10.1 million gallons per day while the county can reliably supply a maximum of about 9.7 million. Demand exceeds capacity by around four percent, and you cannot issue meters against water you do not have.
Is relief actually coming?
Yes, and it is physical rather than procedural. Improved filtration at the Upcountry treatment plants is expected to add roughly 1.5 million gallons a day of treatment capacity, lifting reliable supply from about 9.7 to 11.2 million gallons per day.
That is a genuine change in the arithmetic, and it is the first thing in years with the potential to move a meaningful number of applicants off the list. What I would caution against is timing a purchase on it. Infrastructure schedules move, and a buyer who needs water on a fixed timeline should not be underwriting on a projection.
Private wells, catchment and shared systems
Where county water is unavailable, Maui properties commonly rely on a private well, a shared private water system, or rain catchment. These can work extremely well. They also carry questions a county meter does not.
For a private well: who owns it, what does the permit allow, what is the tested yield and quality, and who pays when the pump fails? For a shared system: how many properties draw on it, what does the governing agreement say, and how are costs and repairs allocated? For catchment: what is the tank capacity, what is the filtration setup, and what does a dry season actually look like on that parcel?
None of these are reasons to walk away. Plenty of exceptional Upcountry properties run on private water. They are reasons to have the documentation in hand before you are committed.
County water comes with its own limits
Buyers often assume a county meter settles the matter. It largely does, but even on county water there can be limitations on the number and type of water fixtures a property may install, which matters if your plans involve a larger home, a guest hale, or the kind of spa and wellness build-out many buyers now want. If your vision includes a pool, a plunge, an outdoor shower and a guest structure, confirm what the meter and the system will actually support before you design around it.
The water due-diligence checklist
- Does the property have an existing county water meter? Confirm on the record, not from the listing.
- If not, does it hold a position on the Upcountry list, and where? A transferable position has real value.
- If it is on private water, get the documents. Well permit, yield and quality testing, shared-system agreement, maintenance history.
- Ask what the meter supports. Fixture limits shape what you can build.
- Match the answer to your timeline. A parcel that may have water in several years is a different purchase from one that has it today.
Frequently asked questions
Can I get on the Upcountry water meter list today?
No. The Department of Water Supply stopped accepting new applications for the Upcountry service area on January 1, 2013. The existing list is being worked through, but it is not open to new entrants.
How long is the Upcountry water meter waitlist?
Approximately 1,424 applicants as of the list dated January 1, 2026.
Which areas are on the Upcountry water system?
Kula, Makawao, Pukalani, Haliimaile, the Maunaolu College area and Haiku.
Can I build on Maui land without a county water meter?
Often yes, using a permitted private well, a shared private system or catchment, but it depends on the parcel and on county requirements. This is exactly the question to resolve before you buy rather than after.
Does a county water meter limit what I can build?
It can. There may be limits on the number and type of water fixtures on county service, which is worth confirming if your plans include a large home, a guest structure or extensive wellness amenities.
