* To obtain Agricultural Quantity Charges, a service holder must submit a written application each fiscal year to the Board of Water Supply and furnish satisfactory proof that they are engaged in crop production, stock raising or dairy farming on a commercial basis. Each approved application shall continue in effect entitling the service holder to these charges for the remainder of the fiscal year, until they cease the activities entitling them to these charges, or until new charges are established.

** The Nonpotable Quantity Charge effective from July 1, 1993 shall not supersede existing or individually negotiated nonpotable quantity charge agreements.

STANDBY CHARGE: A Standby Charge will be negotiated by the Manager and Chief Engineer with private water systems contracting for Inter-connection service. Such service shall be provided only for emergency or unscheduled service outages or supply reductions with the intent to protect against interrupted water service supporting normal private system requirements. Water drawn shall be charged at the applicable quantity rate for each thousand gallons or portion thereof.

ON-SITE DISTRIBUTION TARIFF: Consumers may be assessed an On-Site Distribution Tariff for Department maintenance of property piping if they elect to have the Board provide such service. Maintenance shall be limited to repair and renewal of "after the meter" service appurtenances eligible for coverage

POWER COST ADJUSTMENT: When total electricity costs to the Board of Water Supply exceeds the amount used in calculating the annual Schedule of Rates and Charges, then the Quantity Charge may be increased $0.01 per 1,000 gallons for every $600,000 incremental overage, or any fraction thereof, in the following fiscal year rate.

ENVIRONMENTAL REGULATIONS COMPLIANCE FEE COST ADJUSTMENT: The Quantity Charge may be increased $0.01 per 1,000 gallons for each $600,000 or fraction thereof of additional costs that the Board of Water Supply is required to incur in order to comply with any Federal or State environmental law or regulation.

About the Board of Water Supply Rate Changes

HONOLULU, AUGUST 22, 2011 – The mission for the BWS is to provide safe and dependable water supply now and into the future. It is at the core of what we do and provides the foundation for our work. Our goals are to sustain the island's water resources, maintain a healthy organization, and provide our people with the tools and skills we need to serve our customers.

Our aging system needs continued investment to keep it in operation. More than 45 percent of our pipelines are older than 40 years old, and many are nearing the end of their expected service life. Water utilities across the country are facing this same challenge.

Over the past year, we've studied our system needs and worked to define the true costs of providing water service. Every component critical to delivering water, source, storage, transmission/distribution, and treatment, was closely analyzed and planned for to ensure sustainability and viability for future generations. The results tell us that we must raise rates to continue providing a safe and dependable water supply to our customers.

At the same time, the costs of providing service have grown steeply - electrical power, materials, fuel, and labor costs continue to rise.

To minimize impacts on customers, the BWS has spread the needed increase over a multi-year rate schedule. In the first year of this program, BWS is implementing a system-wide rate increase of 9.65 percent, which represents a $6.99 increase in the average residential customer's monthly charge. This means the water rate will go from $2.79 to $3.06 for 1,000 gallons of water. The new water rates will take effect on January 1, 2012. BWS has timed this rate increase to take effect in the winter months, when residential customers are normally using less water.

At the BWS, we work hard to sustain resources and control costs. Our leak detection program has saved 1.4 million gallons of water a day on Oahu, which equates to about 506 million gallons of water per year. We're producing 8.6 million gallons a day of recycled water, offsetting demands on groundwater.

Concurrently, we continue to look at the portion of our annual operations budget that we can control and are exploring every opportunity to reduce costs. We are committed to continuing to provide the best possible value to our customers.
