This is the largest surface water treatment facility on Maui. It is located approximately 1,120 feet above sea level and relies on flow from the Wailoa Ditch. The facility has four booster pumps to move water up to the 2,800-foot elevation, where it can be pumped to the highest service areas at 4,500 feet (Haleakala Acres). The Kamole WTF is the primary source of water for nearly all of Upcountry during times of drought.
Treated water from the facility goes to 6,687 services and can supply water to almost the entire region (9,865 service) if necessary. Kamole is one of the largest microfiltration facilities for surface water in the U.S.A. Kamole's average daily production is 3.6 million gallons per day.
Originally built in the early 1970s, Kamole was upgraded to Memcor microfiltration, which was put into service in June 1998.
This facility won the American Public Works Association Hawaii Chapter 1999 Project of the Year in the Environmental $2 - $10 million Category.
