Maui Island Water Use & Development Plan

The Maui Island Water Use and Development Plan (WUDP) provides a plan for the protection, management and use of water resources on Maui by all water users over a 20 year period. Each county prepares a WUDP as a component of the statewide Hawaii Water Plan. The Draft Maui WUDP Update was approved by the Board of Water Supply in January 2019 and submitted to the Maui County Council in March 2019 for adoption by ordinance.
