The following page explains the details on a standard tariff sheet.

Tariff Sheet Key

1. Quantity Rates. The quantity rate is the amount customers are charged based on the amount of water they use in a billing period. This rate is approved by the California Public Utilities Commission (CPUC) based on usage forecasts and may vary by service area. The quantity rate is listed on the tariff sheet in cubic feet (cu.ft.) and listed on the bill per hundred cubic feet (CcF). One cu.ft. is equivalent to 7.48 gallons, and one CcF is equivalent to 748 gallons. To convert cu.ft to CcF, simply divide the number of cu.ft. by 100.

Standard Equation. 100 cu.ft / 100 = 1 CcF (748 gallons)

Rate Tiers. Golden State Water has tiered rates in multiple service areas to encourage responsible water use. The tiers may vary by service area and are established based on average usage for that customer base. To calculate the amount of CcFs that define each tier, use the standard equation and input the numbers provided for quantity rates on the given tariff sheet.

Example using the above tariff sheet:

Tier 1: 1,500 cu. ft. / 100 = 15 CcF
Thus, the first 15 CcF of water used is billed at the Tier 1 quantity rate.

Tier 2: 1,200 cu. ft. / 100 = 12 CcF
Thus, the next 12 CcF of water used is billed at the Tier 2 quantity rate.
(For a customer using 17 CcF of water, the first 15 CcF is billed at the Tier 1 quantity rate, and 2 CcF is billed at the Tier 2 quantity rate) 

Tier 3: 2,700 cu. ft. / 100 = 27 CcF
Thus, any water usage over 27 CcF is billed at the Tier 3 quantity rate.
(For a customer using 29 CcF of water, the first 15 CcF is billed at the Tier 1 quantity rate, 12 CcF is billed at the Tier 2 quantity rate, and 2 CcF is billed at the Tier 3 quantity rate ) 

Rate Tiers for Bimonthly Customers. The tier quantity rates listed on the tariff are based on a monthly bill cycle. To determine the water allowance in each tier for a bimonthly bill cycle, multiply the number of CcF in each tier by two.

Example using the above tariff sheet:

Tier 1: 15 CcF x 2 = 30 CcF
Thus, the first 30 CcF of water used is billed at the Tier 1 quantity rate for bimonthly customers.

Tier 2: 12 CcF x 2 = 24 CcF
Thus, the next 24 CcF of water used is billed at the Tier 2 quantity rate for bimonthly customers.

Tier 3: 27 CcF x 2 = 54 CcF
Thus, any water usage over 54 CcF is billed at the Tier 3 quantity rate for bimonthly customers.

2. Service Charge. The service charge is a monthly (or bimonthly) charge applied to all customers regardless of how much water is used. The service charge may vary by service area and is approved by the CPUC to ensure water utilities can recover a portion of the fixed costs associated with operating, maintaining and improving the water system. The service charge listed on the tariff sheet is for a monthly billing cycle. To determine a bimonthly service charge, simply multiply the service charge by two.

Example using the above tariff sheet:

The monthly service charge for a 5/8 x 3/4-inch meter is $17.04 per month. For a bimonthly account, the service charge for one bill period is $34.08 ($17.04 x 2).
