Kaiser Permanente Kona Medical Office Building
REDI was the project lead designer of an innovative onsite wastewater treatment system using several different constructed wetland technologies. In collaboration with Richard Matsunaga & Associates and the wetlands were engineered to target to remove additional nutrients before being 100% reused onsite for landscape irrigation. Working with Maryl Group, Natural Systems International and EcoSoluions, the project became a design-build which streamlined the installation to reduce overall costs to construct for the Owner. Following construction, Kaiser Permanente contracted REDI to operate and maintain the system. The O&M package included educational training opportunities for Kaiser’s staff to learn more about the technology and how it works. The project is seeking LEED gold status.
Kalepolepo Beach Park & NOAA Whale Sanctuary
Kihei, Maui, Hawaii
In partnership with the Water Institute for Sustainability Education. REDI and its team designed-built a shower treatment garden for the Kalepolepo Maui County Beach Park showers. The project also included the design of a series of rain gardens for managing stormwater coming from the Maui NOAA Whale Sanctuary building roof and parking lot. The system was designed such that the treated greywater from the showers is used for irrigating the rain garden during non-rainy periods. REDI also provided educational outreach to NOAA and the community members.
Composting Toilets & Greywater Design for Island Residents & Visitors
Mokauea Island, Oahu Hawaii
REDI led the design and installation of greywater treatment systems and compost toilets for the Mokauea Island residents. The project was retrofit to update the islanders' wastewater management systems to meet State of Hawaii Department of Health regulations while offering an affordable option that highlights sustainability.
Windward Mall Bioretention Systems
Kaneohe, Oahu Hawaii
In partnership with Hui o Koolaupoko, REDI led the design-build of retrofitting three existing landscape sites around Windward Mall into three bioretention systems (rain gardens) to capture, treat and recharge stormwater from sections of the Mall’s parking lots.
Ernie Els Golf Course
Hoakalei Country Club, Ewa, Oahu Hawaii
REDI served as the prime designer for the design-build project of incorporating constructed wetlands into Pond #13 on the Ernie Els golf course to reduce algal blooms caused by high nutrients in the groundwater and from runoff. The constructed wetlands were designed to provide ongoing treatment, aesthetic value and serve as habitat to native Hawaii fauna.
University of Hawaii Manoa Architecture Lab Build Lightly Project
Kalihi, Honolulu, Oahu Hawaii
REDI was the lead design-build partner for implementing greywater gardens for the University of Hawaii School of Architecture Build Lightly Project. The Build Lightly project was a hands-on, project-based class where future architects learned to design and build lightly using local and sustainable materials.
University of Hawaii Maui College Bioretention System
In collaboration with the Water Institute for Sustainability Education (WISE), the Sustainable Living Institute Maui (SLIM) at the University of Hawaii Maui College, and Tri-Isle RC&D, REDI led the design-build an educational rain garden to treat and recharge stormwater onsite harvesting stormwater from one of the Maui Campus Buildings. The rain garden, planted with native Hawaiian plants, located within the SLIM Community Garden space, bringing together local food production and ecological stormwater treatment practices. The rain garden treats and infiltrates up to 270,000 gallons annually onsite.
Hale Mauilola, Sand Island
In partnership with Contain Storage Hawaii, REDI is providing design-build services for a 10,000 square foot greywater garden for the city and county of Honolulu's Hale Mauilola transitional housing community. The greywater garden will be using up to 2700 gallons per day of shower and lavatory water for irrigation of edible and tropical flowering plants. The goals for the greywater garden design were to reduce potable water use, reduce pumping and hauling costs for the wastewater and provide economic resources for the residences.
