Understanding Your Honolulu BWS Bill: Water Charges, Sewer Charges, Usage and Rate Changes
A Honolulu customer may see both water-related charges and sewer-related charges. BWS handles the water bill process, while sewer billing questions are connected with the City and County of Honolulu Department of Environmental Services.
Water use
Your water consumption is one key driver of the bill. Compare current usage with older months to catch unusual jumps.
Water rates
BWS posts current water rate schedules and rate information on its official website.
Sewer fees
For sewer charge details, use Honolulu ENV resources or call 808-768-3330.
| Bill Item | What It Means | Action You Can Take |
|---|---|---|
| Water usage | Amount of water used during the billing period. | Compare usage with previous bills and check for leaks. |
| Water service charge | Fixed or service-related portion depending on meter/account. | Review BWS rate schedule for current charges. |
| Sewer base charge | Fixed sewer cost linked to municipal sewer service. | Call ENV at 808-768-3330 for sewer billing questions. |
| Sewer usage charge | Usage-related sewer charge based around water consumption rules. | Check if a submeter or adjustment applies to your situation. |
| Past due amount | Unpaid balance from earlier billing period. | Call BWS early to ask about payment arrangement options. |
Real Honolulu BWS Bill Pay Tips That Save Time, Stress and Late Payment Problems
These practical tips help homeowners, tenants, landlords, property managers and small businesses avoid wrong-account payment, late mail posting, sewer confusion and payment arrangement delays.
Use the official portal, not a random bill-pay ad
Search results can show third-party bill-pay websites. Start from boardofwatersupply.com or use myaccount.boardofwatersupply.com directly.
Call early if you cannot pay full balance
BWS says flexible payment arrangements may be available. Waiting until shut-off pressure makes the situation harder.
Do not mail close to the due date
For mailed payments, the payment must reach BWS by the due date. Use online or phone payment if the due date is very near.
Separate water and sewer questions
BWS handles the bill/payment process, but sewer fee details belong to Honolulu Department of Environmental Services.
Keep account number with every proof
When saving receipts, include account number, service address, date and confirmation number. This helps customer service trace payments.
Watch outdoor usage in dry months
Oʻahu irrigation, landscaping, pools and hose leaks can create large changes in water use before the customer notices.
Honolulu BWS Customer Service Phone Number, Office Address, Mailing Address and Map
Use the right phone number for the right issue. This saves time because payment, water trouble and sewer billing are not the same department path.
