Ma'alaea Regional Wastewater Reclamation System

Reef Power has provided technical administration duties for the Ma‘alaea Village Association Wastewater Working Group's Ma‘alaea Regional Wastewater Reclamation System (MRWRS) project since October 2021, and has organized the Ma’alaea Wastewater Association, a new mutual benefit nonprofit organization formed to build and operate MRWRS.

MRWRS will replace the failing and inadequate treatment systems and harmful disposal via injection wells with an advanced wastewater treatment system that is located away from the shoreline and outside the tsunami zone and uses 100% irrigation reuse disposal methods. An updated regional wastewater reclamation system is a core requirement to stabilize and restore reef ecosystems and recreational areas in Ma’alaea.

The project has been awarded Maui County Office of Economic Development and Hawaii state legislature Grant in Aid awards, and Maui County Mayor Bissen has pledged to propose a FY2025 grant to build MRWRS.
