Special Conditions - Strawberry Annual General Metered Service
  1. The annual service charge applies to service during the 12 month period commencing January 1 and is due in advance. If a permanent resident of the area has been a customer of the utility for at least 12 months, the residents may elect, at the beginning of the calendar year, to pay prorated service charges in advance at intervals of less than one year in accordance with the utility's established billing periods. Meters will be read and quantity charges billed monthly, bimonthly, or quarterly in accordance with the utility's established billing periods except that meters may be read and quantity charges billed during the winter season at intervals greater than three months.
  2. The opening bill for meter service, except upon conversion from flat rate service, shall be established after the first day of any year, the portion of such annual charge applicable to the current year shall be determined by multiplying the annual charge by one three-hundred-sixty-fifth (1/365) of the number of days remaining in the calendar year. The balance of the payment of the initial annual charge shall be credited against the charges for the succeeding annual period. If service is not continued for at least one year after the date of initial service, no refund of the initial annual charges shall be due the customers.
  3. All bills are subject to the California Public Utilities Commission (CPUC) Reimbursement Fee set forth in Schedule No. UF.
  4. In the event that a customer terminates service under this schedule and reinstates service at the same location within 12 months, there will be a reconnection charge equal to the minimum charges which would have been billed had the customer not terminated service.
  5. A late charge will be imposed per Schedule No. LC.
  6. In accordance with Section 2714 of the Public Utilities Code, if a tenant in a rental unit leaves owing the company, service to subsequent tenants in that unit will, at the company's option, be furnished on the account of the landlord or property owner.
  7. The CPUC granted and approved on January 1, 2020, for the Strawberry District an Interim Rate Increase, followed by Resolution No. W-5229 dated August 6, 2020, granting a General Rate Increase and eliminating the $10.54 Lost Revenue Surcharge. With approval of this Advice Letter No. 523, DOWCST is granted reimbursement of the under-collected revenues in the amount of $43,215.15 as a one-time surcharge over approximately forty-eight (48) billing cycles at $2.29 per customer per month, or until the net shortfall is reimbursed.
