Kuilei Place

High-rise multifamily residential community

Kuilei Place is a planned 43-story luxury residential project in Honolulu, HI that will utilize Epic’s OneWaterTM system to reduce the project’s total water demand by nearly 24%. The system will recycle up to 30,000 gallons of greywater per day and reuse it for toilet flushing in its 1,005 units and irrigation of its lush 1,100,000 square foot property.

The system will treat 8.5 million gallons of water per year collected from the building’s showers, sinks, baths, and washing machines, saving around $133,000 annually in utility costs. Epic Cleantec is overseeing the design, permitting, and implementation of the greywater system. This collaboration ensures seamless integration and adherence to the highest standards of efficiency and sustainability.

A first-of-its-kind for the state of Hawaii

With the approval of Hawaii Department of Health, the City and County of Honolulu’s Department of Planning and Permitting, Department of Environmental Services, and the Honolulu Board of Water Supply, Kuilei Place is positioned to be a trendsetter as the first residential project to meet all requirements established to employ an advanced onsite greywater treatment system.

“As a third generation kama‘āina developer, we are committed to doing our part to lighten the environmental impact and conserve the island’s precious water resources for future generations. By bringing this innovative technology to Hawaii and integrating it into our residential developments, we prioritize water conservation without compromising safety or lifestyle.

This accomplishment is a testament to the collaborative efforts of our partners in the state, city, and private sector. It is our hope that Kuilei Place’s greywater recycle and reuse system will serve as a model for future sustainable development practices statewide.”
