HONOLULU — After receiving approval from the Hawaii Department of Health and the City and County of Honolulu, Kuilei Place, a new condominium development in Diamond Head, Waikiki and Kaimuki, will be the first of its kind in the state with its own onsite greywater treatment recycle and reuse system.

What You Need To Know

  • The greywater treatment recycle and reuse system will take water from the condominium’s sinks, showers and washing machines and put them through a rigorous treatment process onsite

  • The treated water will then be reused in toilets and irrigation systems throughout the property

  • Kuilei Place is the first residential project to meet all requirements established by Hawaii DOH, City and County of Honolulu’s Department of Planning and Permitting, Department of Environmental Services and the Honolulu Board of Water Supply to employ the advanced treatment system within its infrastructure

The system will save nearly 11 million gallons of water each year — an equivalent of more than 16 Olympic-sized swimming pools.

“The approval of a greywater treatment system at Kuilei Place showcases groundbreaking innovation and sustainable design taking place here in Hawaii,” said Mayor Rick Blangiardi in a news release. “By working together across government and the private sector, we can preserve our natural resources and create a more sustainable path forward for all Oahu residents.”

“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,” said Alana Kobayashi Pakkala, Executive Vice President of Kobayashi Group.

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,” said Pakkala.

Kuilei Place will include over a thousand residences featuring one to three bedrooms and is scheduled to break ground in 2024 with an estimated completion date of early 2027.
