How to Pay a Maui Department of Water Supply Bill Online

1. Open the official County water bill payment page.
   Start here: Maui County Pay Your Water Bill.

   You can use the County payment portal for water and sewer bills or log into the online billing account system if you manage your account online.

4. Review fees before confirming.
   Maui DWS says administrative fees may apply and that Point & Pay convenience fees are charged by the payment service provider. Review all fees before submitting.
5. Save the receipt.
   Keep your confirmation number, email receipt, or screenshot until the payment appears on your account.

Maui Water Bill Payment Options and Best Use

Maui DWS gives customers several ways to pay. The safest option depends on whether the bill is routine, urgent, automatic, mailed, or tied to a high-bill or delinquent-account issue.

Automatic Bill Payment for Maui Water and Sewer Bills

Maui DWS offers Automatic Bill Payment, also called ABP. This service lets your participating bank, savings and loan, or credit union pay your water and sewer bill automatically by deducting the amount due from your financial account.

1. Open the official Automatic Bill Payment page.
   Start here: Maui DWS Automatic Bill Payment.
2. Complete the authorization form.
   Fill out the ABP Authorization Form using the same account details shown on your Maui water bill.
3. Attach a voided check.
   DWS says to attach a check marked “VOID” showing your complete financial account number and the name of your financial institution.
4. Mail it to Customer Service.
   The ABP page lists: Department of Water Supply, Customer Service Division, 200 South High St., Wailuku, HI 96793-2155.
5. Watch the first deduction.
   DWS says deductions are made 20 days after the bill is generated. Keep paying manually until you are sure ABP is active.

Report Maui Water Leaks, Main Breaks, Low Pressure or Water Quality Concerns

Billing customer service and emergency water service are not the same. If you see a broken main, leak, low pressure issue, emergency water shut-off need, water meter leak, fire hydrant leak, or water quality concern, use the 24/7 Water Service Helpline.

1. Call the helpline first.
   Do not wait for billing hours if the issue involves flowing water, low pressure, a broken main, or possible water quality concern.
2. Give the exact location.
   Share the address, nearest cross street, landmark, subdivision, road, or meter/hydrant location.
3. Describe what you see.
   Tell the dispatcher whether water is flowing, pressure is low, water is discolored, a meter is leaking, or a main appears broken.
4. Protect people and property.
   Keep children, pets, and vehicles away from flowing water, sinkholes, or damaged roads.
5. Handle billing later.
   Report the water problem first. If it affects your bill, follow up with customer service after the safety issue is handled.

Maui DWS customer service handles starting or terminating service, general inquiries, meter questions, high bills, address changes, bill payments and delinquent accounts.
