Department of Water Supply – Pay Bill, Contact & Services Guide

Department of Water Supply Quick Facts

Choose the DWS Task You Need

DWS customers usually need one of a few practical actions: paying a bill, stopping a late notice, setting up automatic payment, reporting a leak, checking rates, or visiting the correct district office.

How to Pay a Department of Water Supply Bill Online

The fastest official online method is the DWS customer payment portal. The DWS homepage says the portal requires the Zip+4 and 10-digit account number printed on your water bill.

1. Open the official payment portal.
   Use the DWS-linked portal here: Department of Water Supply online bill payment.
2. Use the exact bill details.
   Have your printed bill ready. Enter the Zip+4 and 10-digit account number exactly as shown.
3. Confirm the account and payment amount.
   Review the customer name, service address and balance before submitting payment.
4. Save payment proof.
   Keep your confirmation number, receipt email or screenshot until your account reflects the payment.
5. Call customer service for account problems.
   If the account number does not work or the amount looks wrong, call 808-961-8060.

DWS Payment Methods: Which One Should You Use?

DWS gives several payment choices. The best method depends on whether the account is current, late, under shut-off notice, or needs staff help.

Late Bill, Shut-Off Notice or Disconnected Service

DWS states that if payment is not received by the due date, the amount is considered delinquent and water service may be subject to discontinuation. If a shut-off notice is issued, the delinquent amount must be received and posted by the deadline.

1. Read the due date and shut-off deadline carefully.
   Check whether the account is simply late or already under final notice.
2. Use online or phone payment for faster posting.
   DWS FAQ says the quickest way to receive a delinquent payment is online or by phone.
3. Do not rely on mail if the deadline is close.
   Mail can take 5 business days to post and may not protect service near a shut-off deadline.
4. Save the confirmation number.
   Keep proof ready if you need to speak with Customer Service.
5. Call Customer Service if service is at risk.
   For billing questions, call 808-961-8060.

Automatic Bill Payment for DWS Customers

DWS offers Automatic Bill Payment from checking accounts. This is different from storing a card in the online payment portal. DWS FAQ says recurring online card storage is not available, but automatic bill payment is available through checking account authorization.

1. Open the Automatic Bill Payment form.
   Start from the DWS How to Pay Your Bill page and use the Automatic Bill Payment option.
2. Use a checking account.
   DWS lists Automatic Bill Payment for checking accounts only.
3. Submit the completed authorization form.
   Follow the form instructions and keep a copy for your records.
4. Keep paying normally until ABP is active.
   Do not assume your next bill will be auto-paid unless you receive confirmation or see the bill status change.
5. Cancel early if needed.
   DWS FAQ says customers may stop automatic payment by contacting DWS at least 10 days before the due date noted on the bill.

DWS Payment Offices: Hilo, Kona and Waimea

Customers can pay in person at the Hilo Main Office, Kona Baseyard/Office, or Waimea Baseyard Office. Use the office that fits your island location and office-hour needs.

Water Emergency, Low Pressure, Leak or Broken Main

Billing problems and field emergencies are not the same. DWS lists emergencies and field operations at 808-961-8790. The DWS homepage says this emergency line is available 24 hours a day, all districts, for broken mains, low water pressure and leaks.

1. Describe the problem clearly.
   Say whether it is a broken main, low pressure, no water, leak, water discoloration, or other issue.
2. Give a precise location.
   Provide district, road, nearest address, cross street, landmark, or meter location if known.
3. Protect people and property if safe.
   Keep children and pets away from flooded, muddy, or unsafe areas.
4. Take photos only if safe.
   Documentation can help, but do not step into traffic, flooding, unstable ground or utility work areas.
5. Handle billing questions separately.
   First report the water emergency, then contact Customer Service later if the issue affects your bill.

High Department of Water Supply Bill Checklist

A high DWS bill can come from consumption, leaks, estimated readings, meter access problems, the power cost charge, standby charge, or seasonal irrigation. DWS rate information explains that the bill can include standby charge, consumption charge, power cost charge and Energy CIP charge.

Have this ready before calling Customer Service

• Your current bill and previous bill.
• Zip+4 and 10-digit account number printed on the bill.
• Service address and customer name.
• Payment confirmation if you recently paid.
• Photos, repair receipts or plumber notes if a leak was repaired.
• Notes about irrigation, guests, seasonal occupancy or meter access issues.

Water Rates, Power Cost Charge and Estimated Readings

The DWS rate brochure explains that water bills include four main components: standby charge, consumption charge, power cost charge and Energy CIP charge. Understanding these line items helps customers avoid confusing a rate-related charge with a leak or billing error.
