HOW WINTER AVERAGE IS CALCULATED

Residential customers, who do not have a separate meter for irrigation, are billed sewer charges based on their average winter water consumption.  November through February billings for the last three years are averaged.  This average serves as the ceiling for sewer charges for the next year.  If the water consumption for any month is less than the average, the sewer billing will be based on the lesser amount.  By averaging winter usage customers are not billed sewer charges for water uses that do not impact the sewer system.
