Where does your drinking water come from?
Drinking water is transported from the rivers and ground waters of Na Wai Eha, Maui’s Four Great Waters of West Maui, to Ma'alaea Village, where it enters the resident's condo to be used for household activities and is then flushed down the toilet or drain.

Where does your waste water go?
Raw sewage flows from each condo unit into a devoted wastewater treatment package plant in each of 10 condo facilities where levels of treatment are performed from primary to secondary, with various levels of disinfection.

Waste water reaches the pacific ocean
The totality (100%) of the primary or secondary wastewater discharges into groundwater via very nearshore injection wells. The wastewater of varying treatment levels flows a very short distance through groundwater toward the Pacific Ocean, where it emerges often through the reef itself, via openings that present as direct pathways from the contaminated groundwater to the reef, similar to the flow shown with green dye in the video below.

Drinking Water Sources
Interesting Facts about Drinking Water Sources
From County of Maui: "If you live in Upcountry Maui, 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.
