In a recent meeting held by the Hawaii Green Infrastructure Authority (HGIA), discussions illuminated the vital connection between water and energy, emphasizing the importance of green banks in supporting clean water initiatives. The gathering, which took place at the Entrepreneur's Sandbox, showcased HGIA's Equitable Clean Water Initiative, a program designed to address the pressing need for water reuse in the state.

During the workshop, stakeholders from private and nonprofit sectors joined forces with state and local government representatives to explore two significant projects developed by the Kobayashi Group. These projects highlighted the contrasting challenges faced in luxury versus affordable developments, as well as the regulatory landscape and available technologies. Attendees even had the unique opportunity to sample beer crafted from recycled water, a tangible demonstration of the potential for water reuse.

The urgency of these discussions was underscored by the requirements of Act 170, which mandates the use of reclaimed water for non-potable needs in all state and county facilities by December 31, 2045. Despite Hawaii's potential to scale water reuse at the building level, HGIA currently lacks a dedicated funding source to support such financing initiatives.

As the meeting progressed, the challenges of securing federal grants were laid bare. HGIA representatives detailed their efforts to revise work plans and budgets in response to a reduced funding level of $62.45 million, down from the $100 million initially sought. This included issuing multiple Requests for Proposals (RFPs) and drafting essential management plans to meet grant deliverables.

Looking ahead, the recent passage of Act 40 in May 2024, which established a new investment fund, was a point of optimism. However, the hiring of an investment fund manager only in January 2025 means that the administrative rules governing this program are still in development, a process that could extend for over a year.

As Hawaii navigates the complexities of water reuse and energy sustainability, the discussions at the HGIA meeting reflect a growing commitment to innovative solutions, even as challenges remain. The path forward will require collaboration, creativity, and a steadfast focus on compliance with emerging regulations to ensure a sustainable future for the islands.
