Current Water Rates and Fees

Your Water Bill 


What does my water bill pay for?

The District provides water to the community through more than 14,400 service connections and relies solely on revenue generated from water bills. The District does not receive any income from taxes. Water rates provide the District sufficient revenue to provide a safe and reliable supply of water, maintain and improve infrastructure, encourage ongoing conservation and develop supplemental water supplies to restore the groundwater basin and prevent seawater intrusion. 

How is my monthly water bill calculated?

Your water bill is made up of two types of charges: a monthly fixed service charge and a water quantity charge. Some customers also pay a private fire service charge. Customers are categorized into the following rate classifications: Single-family Residential, Multi-family Residential, Commercial, and Irrigation/Outdoor. Ninety percent of the District’s customers are residential.  Click the button below to calculate your water bill using our bill calculator for Single-Family Residential customers.

Water Bill Comparison Table


Monthly Service Charge

Monthly service charges cover the fixed cost of providing a safe and reliable supply of water, regardless of how much is used. Customers with larger meters have the potential to consume more water. The entire water system has to be sized to meet this potential demand, which results in a higher cost of service for larger meters. Service charges also vary because of differences in peak demand by different types of customers. 

Monthly Service Charge for Residential and Commercial Customers

  Meter Size  Effective January 1, 2020
  5/8" Restricted   $23.48

Monthly Service Charge for Fire Service

These monthly charges are for properties that are required to install a private fire suppression system (e.g. fire sprinklers).  These charges are based on the diameter of the fireline serving the property and are calculated to recover the costs associated with sizing the water distribution system to meet fire flow requirements.

Fireline Size     Effective January 1, 2020
1"  $1.31
2" $8.04
2.5" $14.45

4" $49.72
6" $144.40
8" $307.70


Water Quantity Charges

Water quantity charges are billed for units of water used during the 30-day billing cycle. One unit of water is equal to 748 gallons. Residential customers have a 2-tier rate structure. Tier 1 represents the amount of water the District can safely supply to each household using the existing groundwater supply. Tier 2 represents water use that is above sustainable levels and requires the development of additional sources of water supply.  

The District charges a uniform rate for each unit of water used for customer types that are not residential, which includes Commercial and Irrigation/Outdoor Use customers.

Residential Water Quantity Charges

Tier Units Per Dwelling Rate per unit of water used (effective January 1, 2020)
Tier 1 1-5.99 Units $7.01
Tier 2 6+ units $31.82

Commercial and Irrigation/Outdoor Water Quantity Charge

Emergency Rates

Emergency rates can be enacted by the Board of Directors in the event of an unexpected need to decrease water consumption for such things as water shortages, groundwater emergencies, drought, natural disasters, or other catastrophic events.  The Board of Directors declared a Stage 3 Water Shortage Emergency and enacted Stage 2 Emergency Rates in June 2014 due to the imminent threat of groundwater contamination from seawater intrusion.  In July 2015, the District enacted Stage 3 Emergency Rates. The Board of Directors may declare a water shortage emergency without enacting emergency water rates.  Although the District remains in a Stage 3 Water Shortage Emergency, effective March 1, 2019 we will no longer be charging emergency water rates.
