REDI designs and engineers wetland technologies for commercial water features to maintain high water quality and aesthetic standards, while minimizing operations and maintenance costs. Conventional commercial water features typically have high energy and maintenance costs associated with the control/removal of noxious algae. Wetland technologies such as the Restorer systems are engineered to out-compete algae for nutrients, allowing for a low cost control over an aesthetic nuisance. Importantly the technology is coupled with a low-energy circulation system to maximize the volume of water through the wetland system to remove algae and nutrients. Water features with ecological components and wetland systems can be designed as part of a comprehensive sustainable water management strategy for any given project or site. In addition due to the robust nature of the wetland treatment systems, water features can be converted to low-density aquaculture systems, whereby nutrients are converted to food resources. On the Hualalai golf course, a five-star resort in Kona, Hawaii, this is successfully demonstrated: Wetland Restorers were implemented for water quality maintenance with a return on investment of less than two years. In addition the golf course water feature now provides high quality shrimp and fish grown in the system to the club house restaurant. The project received an EPA award for its savvy design and cost savings.
