1) Proposed Rate Structure Changes

Your water bill is determined based on what it costs to serve water to your home or business. Due to state requirements, the changing water use trends driven by the recent drought, and our fiscal responsibility, we need to reassess our rate structure.

  • We worked with an independent rate consultant to ensure proper allocation of costs among customers. Our proposed rate structure changes align water rates with the cost of your water service, nothing more.
  • These structural changes only affect how rates and charges are allocated among customers; they do not result in additional funds for the District overall. 
  • With the proposed rate structure changes, some customers’ bills will go down, while others will go up depending on their service.


The untreated water rates will be standardized to increase ease of understanding and administration. 

Annual Service Charge – The annual service charge for agricultural irrigation purposes is currently assessed per acre. The service charge is proposed to be assessed the same rate per account. The service charge covers the customer service and billing costs.

Usage Charge – The usage charge covers the cost of purchasing source water, delivery, and conservation programs. The usage charge for agricultural irrigation service has historically been lower than other customer classes. In response to customer feedback on our draft plan, the proposed increase in the usage charge is part of a three-year phase-in of rate adjustments to bring the rates to be the same as for all customers. The current usage charge is $124.92 per acre-foot (or $0.38 per thousand gallons). The proposed standard usage charge for all customer classes is $2.13 per thousand gallons (or $694.02 per acre-foot). The District recognizes that the rate adjustment may have a significant business impact for customers, therefore is proposing to make the usage charge adjustments for agricultural irrigation service over three years. The proposed rate adjustment is $1.47 per thousand gallons (or $478.97 per acre-foot).
