The Board of Directors approved the current rate structure in May 2023. The objective was to cover fixed costs with fixed revenue and variable costs with consumption revenue by restructuring the rate schedule with minimal impact on the average customer. Fixed costs can be defined as expenditures that are incurred regardless of the amount of water used. Variable costs are expenditures more closely tied to the amount of water pumped and delivered.
With the decline in water usage appearing to continue, the Board of Directors has supported the concept of having the Water Availability Rate (base rate) capture a larger portion of the District’s fixed costs. This helps to stabilize the revenue and eradicate the need to chase after a declining variable revenue source, providing increased financial and rate stability.
Before the 2015 rate adjustment, the Water Availability Rate covered 69% of the District’s fixed costs. The 2015 rate structure raised the District’s revenue stability to 83%. The 2016 rate adjustment included the first 3,000 gallons within the Water Availability Rate and brought the District up to 90% revenue stability.
