Water Rates :  Effective July 1, 2023

  Great Oaks Water Company continues to provide water service at the lowest rates of any regulated water utility in Santa Clara County. Information on this page will help you determine how charges on your water bill are calculated.

  The Water Charge on your water bill is made up of two separate calculations: the readiness to Serve Charge (also known as the meter charge) and the Usage Charge (also known as volume charges).

  The Readiness to Serve charge is a monthly charge determined by the size of the water meter serving your property. This charge applies even if no water is used. The monthly charge authorized by the California Public Utilities Commission (CPUC) for General Metered Service for each meter size is listed below.

Meter Size

Monthly Charge

 5/8" x 3/4" $       15.82
 3/4"x 3/4" $       23.73
 1" $       39.54
 1 1/2" $       79.09
 2" $     126.54
 3" $     237.26
 4" $     395.44
 6" $     790.88
 8" $  1,265.40
 10" $  1,819.01
 12" $  2,609.89

  The Usage Charge is determined by the amount of water used during the bi-monthly billing period. Water usage is measured in units of 100 cubic feet (100 cu.ft. = 1 ccf). 100 cubic feet of water is equal to 748 gallons. Single-family residential customers are subject to CPUC-designed tiered rates. All other customers are charged based upon uniform rates.

  Surcharges authorized by the CPUC are mostly based upon water usage. Applicable surcharges are shown on your bill and are more fully described in the tariff pages authorized by the CPUC.

  Water usage charges authorized by the CPUC are shown in the table below.
