Water Rate Structure
The adopted water rate structure is comprised of two components: a fixed monthly service charge (the “Water Utility Charge”), and the variable water consumption charge (the “Water Usage Charge”). Four customer classes have been established – Single Family, Multi-Family, Non-Residential and Recycled Water users. Commodity costs are distributed among them based on each customer class’s total water use. Commodity costs for recycled water are allocated 100 percent to those customers. Utility costs are allocated to each respective customer class based on meter size.
Water usage charges have two tiers based on the source of the water and its availability. The Tier 1 rate recovers the cost of groundwater extraction, the electricity for producing and distributing that water, and some other costs. Tier 2 recovers the costs of purchasing imported water and the electrical costs for distributing that volume of water. The allocation of water in each tier is based on the amount of water supply that is available from each respective source.
Sewer Rate Structure
The variable Sewer Commodity Charge and fixed Service Charge have been replaced by a single fixed Sewer Utility Charge, based on the size of the water meter and customer class.
