How does Hawaii get fresh water?

Asked by: Joshua Ware

Most of Hawaii’s fresh water comes from onshore aquifers, which are layers of rock and soil underground that collect water after rainfall. The team believes that this newfound reservoir is replenished by water flowing out of these aquifers.

Are there water wells in Hawaii?

Because the water table in much of Hawaii is very deep, most wells are drilled wells. But, there may be dug or driven wells on some older properties, par ticularly in coastal and windward areas and areas where they were used for livestock.

How deep are water wells in Hawaii?

Most major productive zones lie 1,219 to 2,134 meters (4,000 to 7,000 ft) below the ground surface (GeothermEx, 1994). The depths of most of the deep wells range from approximately 1,400 meters to over 2,500 meters.

Does Hawaii have underground water?

Ground water is one of Hawaii’s most important natural resources. It is used for drinking water, irrigation, and domestic, commercial, and industrial needs. Ground water provides about 99 percent of Hawaii’s domestic water and about 50 percent of all freshwater used in the State.

Where do Hawaiians get their water?

Water to your home is extracted from the ground from a network of shafts, water tunnels, and many wells located all over Oahu. Except for the North Shore area that is only connected from Waialee to Waialua, an interconnected system from Maakua to Makaha services nearly 98% of the island residents.

Will Hawaii run out of water?

The island of Oahu has sufficient fresh water to supply its near term needs but will begin to strain its fresh water supplies within 100 years. The Hawaii State government estimates that the population on Oahu will increase to about 1,130, which will demand approximately 206 mgd.
