Water Use & Development Plan


The Maui Department of Water Supply is in the process of updating its Water Use and Development Plan (WUDP). Hawaii state law requires each county to prepare, periodically update, and adopt by ordinance a WUDP to serve as the long-range planning blueprint for all uses of water in each county (HRS Section 174(C)-31 and 13-7-170). Each plan must be approved by the State of Hawaii's Commission on Water Resource Management (CWRM). Maui County also requires a WUDP update each time the County General Plan is amended or revised (Maui County Code Section 2.88A). The Plan is required to be consistent with State and County Plans.

The WUDP inventories existing water sources and uses over a 20 year time-frame, discusses existing and future land uses and related water needs, discusses resource impacts of proposed capital and other plans, considers multiple forecasts, sets forth a program by which water needs will be met, and is drafted with credible public involvement.

Public Meetings and Hearings/Documents for Review

Status of Maui County’s WUDP

A WUDP is being adopted for each island of Maui County. Together they will comprise the Maui County WUDP.
  • The March 1990 Maui County WUDP remains in effect for all islands except Lana`i. A copy is also available by contacting the Water Resources & Planning Division at (808) 463-3110.
  • The 2011 Lana`i WUDP has been adopted.
  • The Maui Island WUDP is in the process of being revised. The draft will be available for review in 2017.  Much analysis and public input has already occurred and will be integrated into the plan.
  • Preparation of the Moloka`i WUDP will begin in 2017.
