Wahiawā plant hosts wastewater technology pilot
A three-year pilot at the Wahiawā Wastewater Treatment Plant is evaluating wastewater-treatment technologies. The University of Hawaiʻi’s September 9 report says the Hawaiʻi Onsite Wastewater Technology Evaluation Program launched there on August 26.
UH’s Water Resources Research Center will provide evaluation reports to the state Department of Health. The first system being evaluated, Honu Hub, treats wastewater above ground. The university describes the project as testing that can inform certification decisions; its announcement does not report a completed certification.
