06 — High Bill, Meter Reading & Usage Checks

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.

07 — Water Emergency, Leaks, Low Pressure, Outages & Water Quality

Who to Call for Maui County Water Emergencies or Service Outages

Billing questions and active water emergencies are different. Use the 24/7 Water Service Helpline for broken mains, leaks, low pressure and water quality concerns.

24/7 Water Service Helpline

808-270-7633

Use for broken mains, leaks, low pressure or water quality concerns.

After service restoration

Flush an outside faucet for about 10 minutes, then run an inside faucet for about 10 minutes if needed.

Cloudy or discolored water

Cloudiness, sediment, air spitting and fluctuating pressure can happen after service interruption, but call the helpline if concerned.

1
For broken mains, leaks or low pressure
Call the 24-hour helpline immediately.

Call 808-270-7633. Give the exact location, nearest cross street, whether water is flowing, pressure status, and whether property or traffic is affected.

2
After a water outage is restored
Flush lines before normal use if water looks unusual.

DWS advises customers to run an outside faucet for approximately 10 minutes to clear sediment, then run a kitchen or bathroom faucet for another 10 minutes to flush indoor plumbing.

3
If you use a separate storage tank
Extra flushing may be needed.

DWS notes that customers with separate storage tanks may consider draining and flushing their tanks after a service interruption.

🚨
Emergency reporting tip: Say whether the issue is a broken main, private leak, low pressure, no water, discolored water or water quality concern. Then give the nearest address and whether the problem is inside or outside.
08 — Maui Water Systems, Account Portal & Conservation

Maui DWS Water Systems and Why Usage Monitoring Matters

Maui County water service is not one single neighborhood system. DWS serves multiple systems across Maui County, and water conditions can differ by area during outages, shortages or repair work.

Central Maui

Includes Wailuku, Paia, Kahului, Puunene and Kihei. This is the system with the most customers.

Upcountry Maui

Includes Kula, Pukalani, Makawao and Haiku. DWS says this is the largest geographically.

Other DWS systems

West Maui, East Maui and Molokai are also part of DWS service areas. Lanai water is provided by a private company.

🌺
Local usage tip: If there is an outage or water shortage declaration in your area, check DWS notices and review your bill/usage history. Maui’s water issues can be very area-specific.
Real Insider Tips

Use the 10-digit account number

DWS asks customers to have the 10-digit water account number ready for electronic payments. Keep your bill nearby.

Use ABP for stable monthly payment

Use drop boxes before the “payment must reach us by” date. The Service Center drop box accepts checks only.

Tip 05

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.
