What to Do If Your Maui County Water Bill Is High
DWS explains that your bill is based on how much water passes through your meter. That means you pay for water whether it is used intentionally or wasted through a leak.
Check your usage history
Use the online account portal to view and download current and prior bills and review your usage pattern.
Read your meter
If the meter keeps moving when all water is off, you may have a leak or running fixture.
Call Customer Service
For billing questions or high bill concerns, call 808-270-7730.
| High Bill Cause | Check First | Practical Action |
|---|---|---|
| Running toilet | Listen for water refill, use dye test if needed | Repair quickly and review next bill. |
| Irrigation or outdoor watering | Sprinkler timer, hose bibs, irrigation lines | Compare watering schedule with billing period. |
| Leak after outage or pressure change | Meter movement, wet ground, broken line, water heater | Call DWS if public-side issue suspected; repair customer-side issues quickly. |
| Billing confusion | Current bill, prior bill, account number, meter read | Call Customer Service at 808-270-7730. |

When calling 808-270-7730, use Customer Service for service transfers and closing bills, Cashiers for delinquent bills/locked meters, and other billing inquiries for general billing questions.
Flush after water service restoration
After an outage, flush an outside faucet first, then an inside faucet. This helps clear air and sediment from household plumbing.
