Water department to implement new water-use and meter-sizing method starting Jan. 1
Beginning Jan. 1, 2026, in accordance with Ordinance 5759 adopted by the Maui County Council, the County of Maui Department of Water Supply (DWS) will implement a new method for projecting water demand and sizing water meters that focuses on daily water usage instead of the Hunter Curve Method, which was based on the number of plumbing fixtures—such as toilets or showers—in a building. The new method will apply to building permit applications and applications for new or additional water use.
