Water Management Areas

Wailuku River, Maui, Hawaii.Surface Water Management Areas are special areas designated by the Commission requiring users of surface water sources (such as streams, diversions, and ditches) to obtain surface water use permits to withdraw and use water for various purposes. Individual surface water management areas basically coincide with individual hydrologic units (watersheds).

The State Water Code, Chapter 174C, Hawaii Revised Statutes, authorizes the Commission to designate water management areas for surface water use regulation where the Commission, after research and investigations, and consultation with the appropriate county mayor, county council, and county water agency, and after public hearing and published notice, finds that serious disputes respecting the use of surface water resources are occurring.

Surface Water Management Areas

Any person who is making, or who proposes to make a withdrawal, diversion, impoundment, or consumptive use of surface water in the designated area will be required to apply for a surface water use permit (WUP) from the Commission. However, no WUP is required for domestic consumption (use of water for personal needs and for household purposes) of surface water by individual users, for users on any Maui Department of Water Supply water system, and for the use of rain catchment systems to gather water.
