The BWS has been absorbing the fees the bank charges for the processing of credit card transactions. Unfortunately, due to the renewed terms of the BWS’s contract with the bank, the BWS can no longer afford to include non-residential customers (customers who are not billed at the single-family residential water rate) in this payment option.
Customers who are not billed at the single-family residential water rate are affected by this change. This includes multi-family residential, agricultural, non-residential, and non-potable water customer accounts.
Yes as payments for both are handled by the Board of Water Supply. The credit card acceptance policy applies to all bills for accounts that do not pay the single-family residential rate either for water or sewers.

The Board of Water Supply’s mission is to provide a safe, dependable, and affordable water supply now and into the future for the island of Oahu. The water rate funds the maintenance and replacement of the island’s aging water infrastructure to meet the BWS’s operational requirements and to ensure system reliability.
The funding will facilitate proactive pipeline replacement to minimize water main breaks and also will be used to renew the BWS's pumps, reservoirs, and treatment plants. The BWS maintains nearly 2,100 miles of pipeline servicing nearly every community on Oahu. More than 40 percent of these pipelines are between 30 and 60 years old. Other components essential to the water delivery system are also in need of proactive maintenance. This includes 194 potable water sources, 192 booster pump stations, and 171 potable reservoirs.
The BWS’s Billing or Customer Charge is designed to recover fixed or uniform costs that are associated with furnishing water service, whether or not any water is used. The charge recovers costs such as meter reading, billing, collection and other costs that BWS incurs equally per customer or account. The billing charge is applied monthly in conjunction with the generation of each water and sewer bill. Currently, each customer is charged $9.26 for each bill rendered.
To support the BWS mission to provide a safe and dependable water supply amid rising costs of providing service, the BWS raised water rates in 2012. The rate increase was spread over several years to reduce the impacts on customers.
The first installment of a multi-year rate increase took effect on January 1, 2012. The BWS timed this rate increase to take effect in the winter season when residential customers are normally using less water. The fifth installment took effect July 1, 2015, where the monthly Billing Charge increased from $8.44 to $9.26; a difference of $0.82 per month. The water Quantity Charge also increased from $4.03 to $4.42 for 1,000 gallons of water for the average residential customer.
While the BWS recognizes the impact of the rate increase on its customers, the core components to Oahu's water system need to be restored and replaced to minimize water loss and service disruptions. Additionally, the cost for day-to-day operation of the BWS system, such as electric power, fuel, materials, and labor, continues to rise beyond its control.
Prior to 2012, the last rate increase for the Board of Water Supply took effect July 1, 2010, when the system-wide rate was increased by approximately 5 percent.
Effective July 1, 2015, the Board of Water Supply (BWS) increased the system-wide water rates by 9.68 percent. The monthly water bill for the average BWS customer using 13,000 gallons per month will be $66.72 (Fiscal Year 2015). Water rates were not increased in 2016.
In 2011, a public notice was issued to announce the new rate schedule and the date of a public hearing. Public comment and testimony were received at a public hearing on Monday, August 22, 2011, at the BWS board room. The public comments received were considered by the BWS Board Members as part of the public hearing process in its subsequent decision on the rate increase.
No, the funds generated by water rates are dedicated to funding capital and operation costs for the water system only. Sewer services are provided by Wastewater Management under the City Department of Environmental Services.
The BWS is committed to cost-efficient operations, and it is doing many things to keep costs down. Every year, the BWS carefully reviews its operating budget exploring opportunities to increase efficiency and reduce costs in every aspect of our operations. This includes exploring opportunities to optimize energy management and facility operations. It also includes controlling the size of its workforce by balancing staffing levels to provide the services needed to maintain, repair, and replace its facilities.
Oahu's water system was built along roadways and public areas throughout the island. As the BWS continues to work to renew our aging system, it recognizes that residents and businesses will be inconvenienced by construction activities. The BWS is committed to work with residents and businesses to manage those impacts as well as we possibly can. Some of the things the BWS is doing to manage the impacts of construction include:
By keeping our system in good working order through planned replacement and repairs, the BWS is helping to avoid unplanned repairs that can mean greater inconveniences and higher costs.
The Power Cost Adjustment provides the Board of Water Supply (BWS) with the ability to recover any electrical cost overages above and beyond what was used to calculate the rate increases. Per the Power Cost Adjustment provision, which was approved in the 2006 rate schedule, the Board of Water Supply (BWS) may charge $0.01 per 1,000 gallons of water used for every $600,000 incremental overage. The BWS will annually review and modify the Power Cost Adjustment so that the adjustment only recovers unanticipated energy cost overages from the prior fiscal year.
From July 1, 2011 to June 30, 2012, the Power Cost Adjustment with be 0.0 cents for every 1,000 gallons of water you use.
The Power Cost Adjustment provides the Board of Water Supply (BWS) the ability to recover any electrical cost overages above and beyond what was used to calculate the rate increases. Per the Power Cost Adjustment provision, which was approved in the 2006 rate schedule, the BWS may charge $0.01 per 1,000 gallons of water used for every $600,000 incremental overage.
$1.7 million (FY09 electrical cost overage)
2.8 cents per 1,000 gallons (Power Cost Adjustment 7/1/2010 to 6/30/2011)
The BWS will annually review and modify the Power Cost Adjustment so that the adjustment only recovers unanticipated energy cost overages from the prior fiscal year.
The Power Cost Adjustment charge will change annually so that the adjustment only recovers unanticipated energy cost overages from the prior fiscal year.
The first Power Cost Adjustment took effect in fiscal year 2009 (7/1/08 - 6/30/09). While the approved annual rate increases implemented beginning in 2006 accounted for some projected electrical cost escalations, unexpected and dramatic increases in fuel prices caused the actual electrical costs to far exceed our projections. The Power Cost Adjustment simply provides the Board of Water Supply (BWS) the ability to recover any electrical cost overages above and beyond what was projected.
After a public hearing, the Board of Water Supply (BWS) Board of Directors adopted a schedule of rates and charges its May 2006 meeting, which included a Power Cost Adjustment provision.
The BWS is committed to cost-efficient operations, and we're doing many things to keep our electricity costs down. This includes running our pumps, when possible, during non-peak hours and upgrading our equipment to more energy efficient models. Additionally, we continuously explore ways to optimize and manage our energy consumption.
Other county water utilities in the state have similar charges:
Other businesses also have similar charges:
A cross-connection is a connection between a public water system or consumer's potable (i.e., drinking) water system and any source or system containing nonpotable water or other substances.
The Cross-Connection Control Section (CCCS) is part of the Board of Water Supply's (BWS's) Customer Care Division. It reviews constructions plans for cross-connection control (CCC), conducts field inspections of backflow prevention assembly (BFPA) installations tests the Board's own backflow prevention assemblies, conducts customer education on the importance of cross-connection control and manages the Board's Annual Backflow Prevention Assembly Testing Program.
Backflow is the flow of nonpotable water or other substances through a cross-connection and into the piping of a public water system or consumer's potable water system.
A backflow prevention assembly is a mechanical device installed in your private property after the water meter. It prevents water already in your property pipes from "backflowing" into the City water system, possibly contaminating the City's potable water system.
Yes, there are several different types of backflow preventers available:
The Board of Water Supply recognizes all of these - except the AVB - as acceptable forms of cross-connection control because they can be tested and repaired in-line.
A Certified Backflow Prevention Assembly Tester must test the device. The certified tester will test your new backflow prevention assembly to ensure that it works and will then fill out a Backflow Prevention Installation and Test form. This form should have been given to you that you when construction plans were being processed for a building permit. The Installation and Test form will be given to you from the Certified Tester. You must sign the bottom portion of the form (Assembly Owner Signature), make a copy for your records and mail, fax or email the completed form to:
Board of Water Supply
Cross-Connection Control Section
630 South Beretania Street
Honolulu, HI 96843
Fax: (808) 550-5550
Backflow prevention controls two types of hazards: pollution and contamination of your drinking water supply. A pollutant is any substance which affects the color or odor of the water, but does not pose a health hazard. A contaminant causes illness or death when ingested.
To ensure that the device is functioning properly. With the exception of the air gap, BFPAs are mechanical units that have internal seals, springs, and moving parts that are subject to fouling, wear, or fatigue. The annual test ensures a properly functioning BFPA, and certifies that the BFPA has not been removed or had a by-pass line installed around it. Air gaps may be tested by conducting a visual inspection.
No, but that is the preferred location. The backflow prevention assembly must be installed on "private property." If the backflow prevention assembly cannot be installed immediately behind the meter, the Board of Water Supply (BWS) will allow the BFPA to be installed somewhere more convenient within the property, but the location must be approved by the CCCS. There can be no connections to the water line between the meter and the BFPA. If the water line passes through a landscaped area, the BWS requires the water line to be concrete jacketed.
No, because this allows the assembly to become submerged in the underground box or vault. It also poses safety hazards to the individual testing and maintaining the BFPA.
Failure to install the required type of BFPA could result in termination of water service as indicated in the Board of Water Supply (BWS) Rules and Regulations Section 2-213. The BWS will work with you to have the required BFPA installed.
Call the Cross-Connection Control Section at (808) 748-5470 and request that a copy be emailed, faxed or mailed to you. You will need your water bill account number or the backflow preventer ID number so the correct test form can be sent to you.
The Board of Water Supply (BWS) requires a Reduced Pressure Principle Backflow Prevention Assembly (PR) to be installed immediately behind your meter and in front of any trees or branches. The installation of the RP must be verified by one of the CCCS technicians prior to conversion to Agricultural Water Rate.
Cross-connection control requirements for irrigation systems serving single-family detached dwellings are under the jurisdiction of the City's Department of Planning and Permitting.
Yes. The CCCS will work with you and try to find the best location or solution for your particular place of business.
The Board of Water Supply (BWS) maintains a database containing all of the permitted backflow devices on Oahu. When your device is due to be tested, the BWS will notify you and provide you with a list of certified backflow prevention assembly testers. It is the customer's responsibility to schedule the test. The customer will also be provided with a backflow prevention device test form.
