Maximizing the use of recycled water is a high-priority for the community, County and State. With drought conditions increasingly threatening water supplies in West Maui and the scarcity of water resources leading to ongoing concern over water access, the community looks to improve resource management. Possibly utilizing R-1 Recycled Water for agricultural purposes, revegetation, and offset of potable water in West Maui, from Olowalu to Honokowai, could positively influence the hydrology of Lahaina and contribute to other restoration efforts. R-1 expansion will also decrease reliance on injection wells.

This project includes a suite of planning, design and construction activities to improve and expand the recycled water distribution infrastructure in West Maui. It will improve, repair and rehabilitate old pipelines, ditches and reservoirs, as well as construct new distribution pipelines, laterals, meters, and other appurtenances to service non-potable water needs from Honokowai to Kāʻanapali. It will expand customer base and usage of recycled water, may potentially provide irrigation to support replanting of native vegetation for erosion control in the impact area and may provide irrigation to a potential firebreak mauka of Lahaina.

1. ‍Expansion of Lahaina Recycled Water Distribution Improve, repair and rehabilitate old pipelines, ditches and reservoirs already in place‍
   ‍
2. Kāʻanapali Resort R-1 Water Distribution System Expansion System expansion to add distribution to Kāʻanapali Aliʻi, Kāʻanapali Beach Hotel, Maui Marriott, Westin Maui, Whaler’s Village, Whaler, Kāʻanapali Royale, Outrigger Maui Eldorado, and Sheraton; total estimated peak R-1 demand of 282,300 gallons per day

3. Honokowai R-1 Water Distribution System
   Design, permitting, management and construction of new R-1 distribution pipelines, laterals, meters and other appurtenances within Honoapiʻilani Highway, Lower Honoapiʻilani Road and Kāʻanapali Shores Place

4. Lahaina Recycled Water Force Main Assessment, design, permitting for the rehabilitation/replacement of an existing 6,700-foot force main, construction of a second force main, pump station, access road and supporting utilities/improvements

Construction complete on expansion of recycled water system surrounding the Lahaina Wastewater Reclamation Facility (WWRF) including in Kaanapali. Next phases are in design, including the creation of higher elevation pressure zones and expansion South toward Lahaina. CDBG-DR funds are conditionally awarded for portions of the project.
