Designed with sustainability in mind, Kuilei Place is excited to mark Earth Day by announcing that it will become the first residential community in Hawai‘i to be home to an on-site greywater treatment recycle and reuse system. Essentially, the system is designed to efficiently treat and reuse greywater, effectively reducing the strain on our island’s resources.

The greywater system will take the water from sinks, showers, and laundry machines and put it through a rigorous treatment process on-site. It will then be reused in toilets and irrigation systems throughout the property. This innovative system will save approximately 11 million gallons of water per year — an equivalent of more than 16 Olympic-sized swimming pools!

“As a third-generation kama‘āina developer, we are committed to minimizing our environmental impact and safeguarding our precious water resources for future generations,” said Alana Kobayashi Pakkala, Executive Vice President of Kobayashi Group. “We’re proud that Kuilei Place is the first residential development in the state to incorporate an advanced on-site water treatment system. By bringing this innovative technology to Hawaiʻi and integrating it into our residential developments, we prioritize water conservation without compromising safety or altering resident’s way of life. 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.”

Kuilei Place is the first residential project to successfully meet all requirements established by the Department of Health, City and County of Honolulu’s Department of Planning and Permitting (DPP), Department of Environmental Services (ENV), and the Honolulu Board of Water Supply (BWS) to employ this type of advanced treatment system in its infrastructure. Regulators and partners include the Hawaiʻi Department of Health’s Wastewater Branch, DPP, BWS, Commercial Plumbing, Ulupono Initiative, Hawai‘i Community Foundation and One World, One Water Group. Through their diligent and coordinated efforts, they have successfully paved an innovative and sustainable path forward for residential greywater reuse in Hawai‘i. Kuilei Place is expected to break ground in 2024 with an anticipated completion date of early 2027.
