** Residential Winter Average Water Usage Calculation – Yearly in February, effective for March’s billing, we recalculate a sewer usage charge based on the average winter water consumption the customer used during the months of December, January and February.  The resulting calculation is the charge the customer will be billed for sewer for the next 12 months.

** Residential Winter Usage Charge for New Customers – New customers that do not have history to calculate a winter average water usage will be charged using a default usage of 6 CCF. So, their Winter Usage Based Charge will be $16.32 until an actual winter average usage can be established.
