About the Facility
The Lahaina WTF is located above Lahainaluna High School, adjacent to a one million gallon water storage tank, which was completed in December 1995. The Lahaina WTF was completed in June 1997 at a cost of about $10 million. The project was paid for in part with State DOE funds in exchange for 100,000 gallons of water per day at no charge for Lahainaluna High School.

This facility uses microfiltration to treat surface water and chlorine to disinfect it after treatment. The facility's source of water is the Kanaha Stream and its average daily production is 1.6 million gallons per day.
