"Average Winter Months Consumption" is calculated before the first billing cycle in May. An Account must have actual consumption for the months of November, December, January, and February. Of these four months, the month with the highest consumption and the month with the lowest consumption are rejected. The consumption for the remaining two months is then averaged to arrive at the "Average Winter Months Consumption" which will determine the maximum amount charged for sewerage.
Example of Calculation:
Billing Month Service Dates Water Consumption
November 2014 10/29/2014 - 11/29/2014 12,000 gallons
December 2014 11/29/2014 - 12/29/2014 18,000 gallons
January 201512/29/2014 - 01/31/2015 11,000 gallons
February 20151/31/2015 - 2/28/2015 14,000 gallons
In the example above, December is the month with the highest water consumption and January is the month with the lowest usage - these months are not used in the calculations. 12,000 (November consumption) + 14,000 (February consumption) = 26,000 26,000 / 2 = 13,000 gallons "Average Winter Months Consumption"
If an account does not have history to calculate, the AWC set by the city is 6,000 gallons.
