Well Water on Molokai: DHHL, CWRM, and Water Rights

On most of Hawaii, getting water to a rural parcel is a CWRM permitting question. On Molokai, it's also a decades-long, sometimes-contested question of who has priority -- Hawaiian Home Lands beneficiaries and taro farmers first, by statute, ahead of everyone else drawing from the same aquifer.

This page covers what's specific to Maui County. For the general explanation, see the national guide.

Why Molokai runs on a different rulebook

Every well in Hawaii needs a CWRM permit, covered on the state hub -- but Molokai is one of only two places in the state (with Waimea, Kauai) where a specific statutory water right applies on top of that ordinary framework. The Hawaiian Homes Commission Act of 1920 gives the Department of Hawaiian Home Lands a dedicated water right tied to its homestead lands, and the 1990 State Water Code went further, establishing that Hawaiian homesteaders and taro farmers working their ancestral lands sit at the top of the state's water-rights priority hierarchy -- ahead of agricultural users, ranching operations, and municipal water systems drawing from the same source. This isn't a Molokai-specific statute so much as a statewide priority rule that happens to matter more concretely on Molokai than almost anywhere else, because the island's small groundwater supply is shared among genuinely competing users.

A three-decade dispute over the same aquifer

The practical stakes here aren't hypothetical. DHHL filed a water use permit application in 1993 for a half-million gallons a day from the Kualapu'u aquifer system to serve homestead uses -- the same year Molokai Ranch and the Maui County Department of Water Supply filed their own competing applications against the same source. Molokai Ranch's separate 1993 permit for 2 million gallons a day from its Well 17, drawing from an aquifer estimated at the time to sustainably yield around 5 million gallons a day, was upheld by a 2001 court decision and then reversed by a 2007 Hawaii Supreme Court ruling that invalidated the Ranch's permit. DHHL's own application sat in this same contested-case process for nearly 30 years before CWRM finally acted on it in 2021 -- a timeline that reflects how genuinely limited and disputed this aquifer's capacity has been, not a bureaucratic formality.

The 2021 decision, and what it actually settled

In July 2021, the Commission on Water Resource Management approved DHHL's long-pending application, allocating roughly 0.595 million gallons a day from the Kualapu'u aquifer to new and existing Hawaiian Home Lands uses on Molokai -- coinciding with the centennial of the Hawaiian Homes Commission Act, a year the Office of Hawaiian Affairs noted had otherwise seen no expansion of Molokai homesteading opportunities for nearly three decades. DHHL and state officials described the decision as opening real new homesteading capacity on the island. It did not, however, resolve every competing claim on the aquifer -- Maui County's Department of Water Supply and Molokai Ranch have continued to pursue their own permit applications for the same source, and CWRM's public materials describe further permit decisions as still pending consideration.

What this means for anyone else trying to secure water on Molokai

For a non-DHHL buyer or builder, the honest framing is that water availability on Molokai is a priority question before it's a technical one. A new well application from a private landowner is evaluated against a hierarchy where Hawaiian Home Lands beneficiaries and traditional taro-farming uses come first by law, in a Ground Water Management Area where the state has already spent thirty years litigating how much water even exists to allocate. That doesn't make private water access impossible, but it means a generic assumption -- "CWRM will issue a permit if I apply" -- doesn't hold here the way it might elsewhere in the state. Confirm current aquifer allocation status and any pending competing applications directly with CWRM, and talk to DHHL's Molokai District Office if the parcel under consideration is anywhere near Hawaiian Home Lands boundaries, before assuming a straightforward path to a private well or a county hookup.
