Grove Farm Surface Water Purification Facility

Grove Farm Surface Water Treatment Plant
Aqua Engineers was sub-contracted by Grove Farm Company to design, build, operate and maintain the first surface water treatment plant on Kauai. The facility utilizes the ultra-filtration membrane process. Raw water from the Kapaia Reservoir is treated by pulling it through the porous walls of the hollow fibers by a partial vacuum applied within the membrane. The initial rated capacity of the plant is based on a firm rate of 3.0 million gallons per day, and a maximum production rate of 4.0 mgd. The filtered surface water services the towns of Lihue, Puhi, and Hanamaulu.
