Where does your drinking water come from?
If you live in Upcountry Maui including Pukalani, your water is surface water from the streams in East Maui, to be treated and disinfected before it is delivered to your home.
-
Where does your waste water go?
Untreated wastewater is conveyed through sewer mains to the Pukalani Wastewater Reclamation Facility, then the water is treated by flat plate membrane bioreactor filtration (MBR) technology to "secondary" standards.

Waste water disinfection & disposal
The water is UV disinfected and almost all of it (97%) is pumped to golf course irrigation at the nearby Pukalani Country Club, while a small portion (3%) is sometimes discharged into a leach field. The wastewater almost completely flows to disinfected irrigation reuse so the small volume discharging into a leach field has a low probability of significantly affecting the ocean, but Upcountry Maui has an issue with some drinking water wells registering levels approaching drinking water limits for nitrate.

Drinking Water Sources
Interesting Facts about Drinking Water Sources
From County of Maui: "If you live in Upcountry Maui including Pukalani, your water is surface water from the streams in East Maui. It's treated and disinfected at one of our three water treatment facilities (Kamole, Piiholo, Olinda) before it's delivered to your home. Customers in Haiku get their water from the Haiku or Kaupakalua wells and/or the Kamole Weir. Hana and Molokai also use groundwater. Lahaina has a mix of surface water and groundwater. The water treatment facilities for West Maui are located above Lahainaluna School and near the Kapalua Airport.
For Central Maui (Kahului, Wailuku, Waihe'e, Waikapū, Waiehu, Ma'alaea, Kihei, Wailea, Makena, Sprecklesville and Paia) your water is from surface and groundwaters of Na Wai Eha, Maui’s Four Great Waters of West Maui, which includes the ‘Īao Aquifer under the West Maui Mountains. That water is naturally filtered by lava rocks, disinfected, and sent to your home. A small amount of filtered surface water is added to the Central System at the Iao WTF."
The Iao and Waihee aquifer region has been designated by the Commission on Water Resources Management as a “water management area” due to over pumping. This points out that water reuse can alleviate stress on our primary drinking water source for Central & South Maui.
