Clean Water Branch
The Clean Water Branch
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 CWB also protects and restores inland and coastal waters for marine life and wildlife. These goals are accomplished 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.
