Empower a Community to Restore and Protect Māʻalaea Bay

Māʻalaea Regional Wastewater Reclamation System

Let’s turn wastewater pollution into a water resource.

Join this community-driven effort to stop the use of the 24 injection wells in Māʻalaea Bay releasing pollutants into the ocean each day.

Māʻalaea Bay has suffered a “Catastrophic ecosystem loss” (DAR/DLNR). Coral reef ecosystem coverage is less than 5%, Limu have disappeared and water quality presents human health risks.

The Māʻalaea Regional Wastewater Reclamation System (MRWRS) will not only tackle wastewater contamination, but will mitigate wildfire risk by establishing a greenbelt fire break.

Further, the R1 water will be used as irrigation in place of the 6 million gallons of potable water currently used by Māʻalaea’s condos for landscaping per year and will support ecological restoration upland.

Māʻalaea Regional Wastewater Reclamation System

The Māʻalaea Regional Wastewater Reclamation System is a holistic solution

  • The MRWRS is a community wastewater treatment facility that will discontinue the use of the injection wells.
  • It will reclaim the water and produce the highest level of recycled water for reuse.
  • The state of the art technology will go beyond R1 requirements by treating nutrients, PFAS, and emerging contaminants which most wastewater treatment plants do not.
  • It will establish a greenbelt firebreak that includes native and functional plant species to protect the community from wildfires.
