The Upcountry Maui Water Meter List: What Buyers Need to Know

If you are looking at land Upcountry, this is the single most important thing nobody tells you until it is too late: the lot may not be able to get water.

Not “water is expensive.” Not “water takes a while.” Cannot get it. There is a waiting list, it is long, and being on it is not the same as being served.

What the water meter list actually is

Maui County’s Department of Water Supply controls water meters Upcountry. Demand has exceeded what the system can reliably deliver, so the county maintains a waitlist. You apply, you get a priority number, and you wait. The current list is dated January 1, 2026 and is published by priority number and by tax map key, so you can look up exactly where a property stands.

As of the county’s own reporting, roughly 1,424 applicants are on the Upcountry waitlist.

Why the list exists

It is arithmetic. Peak Upcountry demand runs about 10.1 million gallons a day. The county’s reliable supply has been about 9.7 million gallons a day. Demand exceeds capacity by roughly 4%, and you cannot hand out meters against water you do not have.

The part that is actually improving

This is where the story gets better than most people realize. The county is installing better filtration at the Upcountry treatment plants, which raises reliable capacity from 9.7 to about 11.2 million gallons a day. Longer term the plan includes six additional wells, largely in the Makawao aquifer area, plus two new reservoirs.

The county has also downgraded the Upcountry water shortage from Stage 2 to Stage 1 after rainfall improved stream flows and reservoirs.

So the trend is genuinely positive. But “improving” and “your lot has a meter” are two different sentences.

What this means when you are buying

Three scenarios, and you need to know which one you are in before you remove contingencies.

The property already has a meter. Best case. The meter conveys with the property. This is worth real money and it is why an Upcountry parcel with an existing meter can be worth substantially more than an identical parcel without one.

The property is on the list. You are inheriting a priority number, not a water source. Ask for the position, the application date, and the TMK it is tied to. Then be honest with yourself about the timeline.

The property has no meter and no position. You are looking at catchment, a well, or nothing. Which is not automatically a dealbreaker. Plenty of Haiku and Kula properties run beautifully on catchment. But it changes your financing, your insurance, your daily life, and your resale pool, and it needs to be priced in.

Catchment is not a consolation prize

Rain catchment Upcountry is normal, legal, and works. Haiku gets serious rainfall. A properly sized tank, a good filtration setup, and a backup plan for dry stretches is a completely functional system, and some owners prefer it to a county bill.

What it is not is invisible. Some lenders treat catchment-only properties differently. Some buyers will not consider them. And a dry year is a real event, not a theoretical one.

The questions to ask on every Upcountry parcel

Does it have a meter, yes or no. If no, is it on the list and at what priority. If catchment, how big is the tank, what is the filtration, and what happens in a drought. Is there a well, and if so what is its permitted use and yield. What did comparable parcels with meters sell for versus those without.

Those five questions separate a good Upcountry buy from an expensive lesson.

Why I care about this more than most agents

I live in Haiku. Water is not an abstraction here, it is a daily fact. Most of the island’s agents work South and West Maui, where you turn a tap and it works. Upcountry is a different set of rules, and the people who get burned are almost always the ones who assumed those rules did not exist.

Send me an address or a TMK and I will tell you exactly what its water situation is before you write an offer.
