Project type
Regenerative Design, Onsite Wastewater Treatment, Green Stormwater Infrastructure
Client
Hōkūnui
REDI provided water-wastewater infrastructure planning for Hōkūnui Maui's 258-acre agricultural, residential and commercial development. REDI provided the design of clustered onsite wastewater treatment systems using ecological technologies to meet water quality suitable for onsite reuse for irrigation. In addition, REDI and its team underwent hydrological studies to determine strategic water management strategies to helped guide land-use choices and facility placement based on the ecological and hydrological capacity of the site and well as costs. Using the hydrological model, stormwater was designed to be conveyed and treated through green infrastructure practices that included swales and ponds for storage for irrigation (re)use. Design support included post-pond filter and irrigation design. In addition, REDI is guiding the site design toward a Net-Zero Water goal by meeting the various building and site water demands by strategically managing stormwater and treating the wastewater onsite for 100% reuse.
