Primary Urban Center Watershed Management Plan

The Honolulu Board of Water Supply (BWS) is developing the Primary Urban Center Watershed Management Plan (PUC WMP), which will be part of the City Water Use and Development Plan under the State of Hawaii Water Code and City and County of Honolulu ordinance. Almost half of Oahu's population resides within the boundaries of the Primary Urban Center. Additionally, the PUC is a designated growth area, requiring planning to meet the demands of a growing population.

The PUC WMP will investigate existing water demand and supply, project future water demands, and identify supply options to meet those demands. Recognizing that fresh water is a finite, protected public trust resource that is essentially linked to the existence of healthy watersheds, the PUC WMP will also identify critical watersheds and develop watershed protection strategies to maintain the quality, quantity, and sustainability of Oahu's water. Thus, the PUC WMP will work to ensure healthy watersheds to sustain our freshwater supply, maximize conservation and other water-saving efforts to reduce the need for costly infrastructure upgrades and where necessary, identify essential infrastructure upgrades to maintain safe, reliable water supplies into the future.

Project Fact Sheet

To learn more about the Primary Urban Center Watershed Management Plan (PUCWMP), review the fact sheet for the project.


To formulate an environmentally holistic, community-based, and economically viable watershed management plan that will provide a balance between:

  • the preservation and management of Oahu's watersheds, and
  • sustainable ground water and surface water use and development to serve present users and future generations.


  1. Promote sustainable watersheds
  2. Protect and enhance water quality and quantity
  3. Protect Native Hawaiian rights and traditional customary practices
  4. Facilitate public participation, education, and project implementation
  5. Meet future water demands at reasonable costs

Community Meetings

The project team has been meeting with community leaders, community groups and organizations, landowners, and public agencies to learn about the issues and activities being undertaken in the PUC. Public meetings are also being conducted to gain input from the larger community.
