This structure rewards customers who reduce water usage through changes in appliances and/or behavior.
For example, a residential family uses 20,000 gallons of water in a quarter. Using the conservation-oriented rate structure for water, the customer would be charged for 12,000 gallons at the Tier 1 water rate ($3.00x12) plus 8,000 gallons at the Tier 2 rate ($4.00x8). No usage would be charged at the Tier 3 water rate, because the customer’s consumption did not exceed 24,000 per quarter. Since the conservation-oriented rate structure only applies to water, for sewer, the customer would be charged 20,000 gallons at the sewer rate ($9.00x20). The customer's total bill would be $248.
