Choose the Maui DWS Task You Need Today

A Maui water bill search can mean several different things. Paying a normal bill, reporting a broken main, starting service, joining automatic bill payment and asking about a high bill all need different steps.

How to Pay Your Maui Department of Water Supply Bill

Maui DWS gives customers several payment paths: online, phone, in-person, mail, secure drop box and Automatic Bill Payment. Choose the option based on how urgent the payment is and whether you want a one-time payment or recurring bank deduction.

1. Start from the official Maui County payment page.
   Use Pay Your Water Bill or the DWS Fiscal / Customer Service Division page.
2. Have your 10-digit water account number ready.
   Maui DWS says you should have the 10-digit water account number available when making an electronic payment.
3. Choose online or phone payment.
   Electronic payment may allow credit card, debit card, electronic check, Apple Pay and Google Pay. Administrative fees may apply.
4. Review the payment screen.
   Confirm the account number, balance, service address and payment method before submitting.
5. Save proof.
   Keep your confirmation number, receipt email or screenshot until your payment appears on your account.

Maui Water Bill Payment Options Compared

The best payment option depends on your timing. Do not use the same method for a routine bill and an urgent bill.

Automatic Bill Payment for Maui DWS Customers

Maui DWS offers Automatic Bill Payment, also called ABP. This is useful if you want your water and sewer bill paid automatically from a bank, savings and loan, or credit union account.

1. Open the official ABP instructions.
   Start here: Automatic Bill Payment.
2. Complete the authorization form.
   Fill in the ABP Authorization Form with your account and financial information.
3. Attach a voided check.
   Maui DWS says to attach a check marked “VOID” showing your complete financial account number and financial institution name.
4. Mail the form to DWS Customer Service.
   The ABP page lists the mailing destination as Department of Water Supply, Customer Service Division, 200 South High St., Wailuku, HI 96793-2155.
5. Watch your next bill.
   Deductions are made 20 days after the bill is generated, giving you time to review the bill and contact DWS with questions.

Report Maui Water Emergencies, Leaks, Low Pressure or Water Quality Concerns

A water emergency should not wait for billing customer service. Maui DWS provides a 24/7 Water Service Helpline for broken mains, leaks, low pressure and water quality concerns.

1. Call the helpline first.
   Do not wait for business hours if you see a broken main, major leak, low pressure affecting multiple homes or water quality concern.
2. Give a clear Maui location.
   Provide the street address, cross street, landmark, meter area or affected neighborhood.
3. Describe what is happening.
   Tell the dispatcher whether you see water flowing, low pressure, discolored water, no water or a possible service line issue.
4. Stay away from unsafe areas.
   Avoid unstable ground, flooded roadways, moving water and places where water may be near electrical hazards.
5. Follow up with billing only if needed.
   Handle the water emergency first. If the issue affects your bill, call Customer Service later with the report details.

Start, Stop, Terminate or Update Maui Water Service

Maui County’s FAQ says customers can open an account, ask account and bill questions, start or terminate water service, or report a change of address by calling DWS Customer Service or visiting the office.

High Maui Water Bill Checklist Before You Call

A high water bill in Maui can come from leaks, irrigation, pool use, guests, drought-season watering, a longer billing cycle or a payment/account issue. Because Maui’s water systems cover different regions, local conditions and restrictions can also affect how customers use water.

Have this ready before calling DWS

• Your 10-digit water account number.
• Current bill and previous bill.
• Service address and customer name.
• Payment confirmation if you recently paid.
• Dates when usage changed or a leak was found.
• Photos, plumber invoice, repair receipt or parts receipt if a leak was fixed.
• Notes about irrigation, pool filling, guests, vacation rental usage or outdoor watering changes.

Maui Water Systems, Shortage Declarations and Conservation Resources

Maui DWS serves several different water systems, and water conditions can differ by region. The County lists five main service sections: Central Maui, Upcountry Maui, West Maui, East Maui and Molokai.
