Maui’s Central-South Maui water system is operating nearly at full capacity during dry months, prompting the county to explore a $53 million desalination plant in Kīhei. The project is in early planning stages and received a cautious reception from community members who want conservation measures prioritized first.
- The Central-South Maui water system delivers 26.79 billion gallons per day during peak dry months, nearly matching its 26.81 billion gallon daily capacity.
- Projected growth could increase regional water demand by 6–10 million gallons per day by 2040, pushing the system beyond its current limits.
- The proposed $53 million reverse-osmosis plant in Kīhei would use solar energy and draw from the brackish Kamaole aquifer system.
- Community members raised concerns about costs and brine disposal, and urged the county to exhaust conservation and water-reuse options before proceeding.
- The county may seek U.S. Bureau of Reclamation funding for planning and design, but officials stress no final decision has been made.
