The District's budget-based tiered rate structure rewards efficient water use while equitably allocating water supply costs and balancing revenue needs for single-family residential customers and irrigation customers. Budget-based tiered rates fairly allocate the cost of water service based on water needs and water supply and operational/maintenance costs. The method recognizes the difference between indoor and outdoor use and rewards customers who use water efficiently with lower water rates.
Water budgets represent an appropriate amount of water to meet customers' efficient water use needs. If customers exceed their budget, they are considered to be using water inefficiently and pay a higher rate to cover higher costs associated with discretionary or excessive water use.
