Poipu Water Reclamation Facility



Poipu Water Reclamation Facility
The original wastewater facility was constructed in 1981 to serve the Poipu resort area and designed to handle 500,000 gallons of wastewater per day. The effluent is used to irrigate the Kiahuna Golf Course. In 2004, the treatment capacity was increased to 1.0 mgd to accommodate the increased development in the area. Aqua Engineers, Inc. replaced the conventional activated sludge process with the Kaldnes Moving Bed Bio-reactor (MBBR) fixed film process. Cloth disk filters and ultraviolet disinfection were installed to upgrade the process to produce R-1 effluent. Briant Construction, Inc. installed new welded stainless steel tanks and equipment for the MBBR process. The tanks were constructed using a new construction method from Italy to reduce costs by 30 percent. Aqua Engineers, Inc. continues to operate the facility, which has become more efficient as a result of the upgrade.
