Each month's sewer charge is composed of the fixed service charge plus the variable commodity charge times the lesser of the following two usage computations:

1) Winter Average - If water consumption for any current month is higher than the winter average, sewer usage is determined by the winter average plus 8%. The winter measuring period is defined as the three consecutive billing periods beginning with the billing period with a billing date in the month of December.

OR

2) Actual Water Consumption - If water consumption for any current month is lower than the winter average, sewer usage is determined by actual water consumption plus 8%. Minimum water consumption is set at 2,000 gallons.
