A $14 million upgrade to the Lahaina Wastewater Reclamation Facility now delivers reliable recycled water to golf courses, resorts, and parks across West Maui. The project, which modernized 1970s-era infrastructure, won the Hawaii Society of Professional Engineers’ 2026 Project of the Year award.
- The upgraded facility reduces demand on Maui’s limited potable water by supplying recycled water to golf courses, resorts, and public parks.
- Advanced automation and process controls eliminate the flow instability that previously damaged equipment and disrupted treatment.
- The project cuts reliance on injection wells, helping protect West Maui’s groundwater and coastal ecosystems.
- Engineers repurposed existing basins and infrastructure to minimize construction waste and lower capital costs.
- The improvements are designed to support both daily operations and long-term wildfire recovery efforts in West Maui.
