How to Pay a Kauaʻi Water Bill Online
Start from the official DOW page

Match the account correctly
A payment can be made by someone else if they have the account number, copy of the bill or physical address to identify the correct billing account. Walmart is the exception because the account holder must pay there.
Check bill amount and due date
Review the bill summary, total due, due date, meter information and usage comparison before submitting payment.
Save proof and call if urgent
Keep confirmation, amount, date, account number and screenshot. For shutoff, missing bill, wrong address or urgent billing issue, call 808-245-5442.

Kauaʻi Water Rates, Service Charge, Power Adjustment and Late Charge
Use this section for understanding the bill structure. For exact current charge application, always confirm on the official Rates and Charges page or with DOW Billing.
Use charge
General use rates are charged per 1,000 gallons using tier blocks. Current official table shows general-use blocks from $3.80 to $10.00 per 1,000 gallons.
Monthly service charge
The fixed monthly service charge is based on meter size and helps recover infrastructure operation and maintenance cost.
Power adjustment
Water consumption is also subject to a Cost of Power Adjustment, reviewed through DOW’s annual budget process and implemented July 1 if applicable.
Late charge
A late payment charge may be assessed at 0.5% per month or fraction against delinquent balance beginning 30 days after the bill date.
| Meter / rate item | Official example from current rate page | Why it matters |
|---|---|---|
| Common 5/8 inch meter service charge | $17.75 monthly service charge shown in the effective 7/1/14 column. | Many residential customers may use this meter size; check your bill under Current Activity. |
| General use 0th block | $3.80 per 1,000 gallons shown in the effective 7/1/14 column. | Minimum/block thresholds vary by meter size. |
| General use 1st block | $4.85 per 1,000 gallons shown in the effective 7/1/14 column. | Higher use can move consumption into higher blocks. |
| General use 2nd block | $5.65 per 1,000 gallons shown in the effective 7/1/14 column. | Useful when comparing a high-use month. |
| General use 3rd block | $9.50 per 1,000 gallons shown in the effective 7/1/14 column. | Outdoor use or leaks can make this block relevant. |
| General use 4th block | $10.00 per 1,000 gallons shown in the effective 7/1/14 column. | High usage costs more per 1,000 gallons at upper tiers. |
High Kauaʻi Water Bill, Low Pressure or Leak Concern
Compare usage first
Use the bill’s usage comparison and meter information. If usage is higher, the issue is usually consumption, leak, irrigation or household change.
Check private plumbing
Low pressure may be caused by a property leak or a failed pressure reducing valve. If neighbors also have pressure loss, it may involve a County line or valve.
Leak adjustment form
DOW lists a Leak Adjustment Request form for undetected underground leaks. The form is listed as in-person only and notary required.
| Problem | What DOW guidance suggests | What to do next |
|---|---|---|
| Bill looks high but usage range is similar | DOW bills by 1,000 gallons, so usage can remain in the same billing range for multiple months. | Compare meter reads and 13-month usage profile, not only dollars. |
| Low pressure | Could be property leak, pressure reducing valve issue, County water line leak, or County pressure reducing valve issue. | Ask neighbors; if they are affected too, call Operations at 808-245-5444. |
| Meter hit or damaged | DOW says to call Operations at 808-245-5444. | Call quickly and provide exact address/location. |
| Leak suspected underground | DOW has a Leak Adjustment Request form for undetected underground leaks. | Review form requirements; in-person/notary may be required. |
| Missing bill | DOW asks customers to call 808-245-5442 or email billing@kauaiwater.org to confirm mailing address and contact information. | Do not wait for another paper bill if you know your cycle is late. |
Service Outages, Emergency Shutdowns and What to Do
Emergency numbers: During business hours, call 808-245-5444 or 808-245-5400 option 1. Nights, weekends and holidays, call 808-241-1711.
Before/during shutdown: DOW advises customers to store enough water, notify family/friends/neighbors, make sure water heaters do not empty, and avoid using appliances that require water during a shutdown.
Cloudy after outage
DOW says cloudy water after an outage can come from tiny air bubbles and should clear if allowed to sit.
Brown after repair
Brown water can come from disturbed pipeline sediment. Run a faucet or outside hose bib for five minutes; call DOW if it persists.
Updates change fast
Emergency shutdowns and repair times can change. Check the Service Outages page and follow DOW updates before assuming service is restored.
Water Quality Questions: Taste, Odor, Milky Water and Reports
Off-odor or taste
DOW says unused water in house pipes can allow microbes in pipes to grow and cause odor or funny taste. Flushing can help.
Milky water
Air trapped in lines can make water look milky. If water clears from the bottom up in a glass, air is usually the cause.
Water quality report
DOW publishes annual Water Quality Reports for systems such as Anahola, Hanalei, Kīlauea, Līhuʻe-Kapaʻa, Kekaha-Waimea and others.
