The Clean Water Branch (CWB) protects the public health of residents and tourists who enjoy playing in and around Hawaii’s coastal and inland water resources. The Clean Water Branch accomplishes this goal through statewide coastal water surveillance and watershed-based environmental management through a combination of permit issuance, monitoring, enforcement, polluted runoff control projects, and public education conducted by the four sections of the Clean Water Branch.

The Clean Water Branch is divided into four sections: Monitoring & Analysis, Engineering, Enforcement & Compliance and the Polluted Runoff Control Program. *Staff at the Kauai District Health Office (KDHO) work under the Monitoring & Analysis Section.

KDHO staff monitor and assess water quality, issue water quality related advisories to protect public health, and submit evidence that appear to indicate non-compliance to the Enforcement & Compliance Section.

For more information on the Engineering Section, Enforcement & Compliance Section and the Polluted Runoff Control Program, please visit the State of Hawaii Department of Health Clean Water Branch Page.

The Clean Water Branch encourages the public to subscribe to receive email notifications of water quality advisories, available on the CWB System Page. Aside from current water quality advisories, this page includes a Frequently Asked Questions section where you may find additional information about our program.
