As a homeowner, investor, or prospective buyer on the Valley Isle, staying informed about local utility adjustments is key to managing property expenses. Starting July 1, the Maui County Department of Water Supply is implementing updated water service rates and tiered usage charges for the fiscal year.
According to county officials, these adjustments are structured to fund over 30 million dollars in annual infrastructure upgrades, ensuring long-term reliability for our island water supply. Most residential users will see only a nominal increase of roughly 1 percent to 2 percent on their monthly bills, while higher-volume consumption tiers face steeper adjustments to support conservation.
Maui utilizes a highly structured, progressive system across multiple property classifications. Under the updated schedule, the regular usage costs per 1,000 gallons are detailed across all consumer sectors below:

Utility updates directly impact ownership costs across Maui's microclimates. Water needs vary wildly between Upcountry estates in Makawao, Kahului rentals, and Wailea luxury condos.
Investors must evaluate these distinct rates across multi-family, resort, and agricultural properties during due diligence. Smart irrigation and native, drought-tolerant plants are now key to maintaining curb appeal while keeping utility bills in check.
Ultimately, these rate hikes fund vital pipe replacements and new water sources, securing long-term property values and sustainable growth island-wide.
