  • Recycled Water

    Recycled water helps meet our island's water needs.

  • Watershed Partnerships

    One of the ways the BWS is protecting Oahu's watershed areas is by entering into partnerships with local and federal agencies, private landowners, schools, and community groups that protect and enhance our watersheds through resource management. Watershed partnerships come in all shapes and forms ranging from studies to Memorandum of Understandings (MOU) to actual on the ground projects.
