Rates & Fees

The District has established rates and charges necessary to maintain an adequate and reliable supply of high quality water. District rates and fees are developed using careful engineering and financial analysis of the cost of service. The majority of the District's costs are fixed, as they relate to facilities and long-term contracts such as State Water Project. Your cost of water is based on a combination of fixed cost and how much water is actually used. All charges reflect a fairness principle that all customers pay for the cost of providing safe and reliable water services -- no more and no less.

Your Bill is Made up of Two Charges

  1. Meter Charge. This is a fixed charge based on your meter size.
  2. Water Rate. This varies by Customer Classification and is based on the cost per unit (HCF) volume. For residential users, it varies by tier according to the volume of water used.

More detail about these charges can be found below.

1) Meter Charge

The meter charge is a fixed charge based on the size of the water meter.

Note: A few properties have multiple meters. If you have questions about multiple meter charges, please contact the District directly.

2) Water Rate

The District completed a 5-Year Financial Plan and a Cost of Service study, and in June, 2020 adopted a five-year schedule of necessary rate increases.

Payment Programs & Billing Policies

Direct Payment Program Terms and Conditions

Direct Payment is a FREE service that allows you to have your recurring water bill paid automatically by credit card or from your checking or savings account. No checks, no postage, no late payments, and no hassles. Direct Payment uses the same network as direct deposit.

The system is safe and reliable. Sign up today here:

If a customer elects to participate in the Direct Payment Program, the amount of the water bill will be automatically debited from the customer's checking or savings account on the 20th of the month or on the following business day.

If a customer should have any questions concerning the charge shown on his/her bill and does not want the amount of the bill deducted from the account, the customer must contact the District and initiate a request within ten days after the billing date. Any such request must be in writing. A copy of the written request should be retained for the customer's records.

If there are insufficient funds in the customer's account to cover the direct payment, he/she will be assessed a $25.00 service charge. The District will then require that the current payment amount be covered in cash, cashier's check or money order. After two such occurrences of insufficient funds, a customer may no longer be eligible for the Direct Payment Program.

Participation in the program may be canceled at any time by giving the District 30 days written notice. A copy of the cancellation request should be retained as a personal record.

Late Charges

A late charge is included on the past due amount of the monthly bill. The late charge will amount to 6% of the first month's past due bill, followed by an additional 1.5% fee for each month thereafter. It covers the District's actual costs of financing late payments from delinquent customers.

Note for New Business Customers

The water bill for a business is directly related to the meter's water budget and entitlement level. Exceeding the water budget will result in water billed at higher tier rates. Businesses—especially those that use large amounts of water such as restaurants, coffee shops, laundromats, etc.—should ensure the meter’s existing water budget/entitlement is adequate for the intended end use. Please contact the District’s Engineering Department at 805-969-2271 for more information and to determine if the existing entitlement is adequate for the intended end use for the site.

The Water Availability Charge (WAC)

Since 1996, the Water Availability Charge has been a key source of funding for Capital Projects.  For properties within the District's service area, this annual assessment of $30 per acre (or per parcel if less than an acre) is collected along with property taxes and is used exclusively to fund water system improvements such as upgrading distribution services, replacing aging infrastructure, and increasing reliability and the ability to meet fire flows. The WAC is reviewed in Public Hearing and renewed by vote of the Board of Directors annually. Review typically occurs during the July Board meeting and current year assessment figures are available at that time.
