Pukalani
Hawaii Water’s Pukalani Water Reclamation Facility is the first wastewater treatment plant in the State of Hawaii to use state-of-the-art flat plate membrane bio-reactor filtration (MBR) technology. It treats 200,000 gallons of wastewater per day to a high-quality effluent used to irrigate the neighboring golf course. Hawaii Water selected the flat plate membrane process because it has a very small footprint, is less costly to maintain, and produces water that can be reused without restriction, freeing up precious potable water supplies. The plant is more reliable and environmentally friendly than the old plant, which was originally constructed over 35 years ago.
Waikoloa
Since 2008, Hawaii Water has provided high quality water and wastewater utility services to homes, condominiums, hotels, golf courses, and shops at Waikoloa Beach Resort and in Waikoloa Village.
