What Is Winter Averaging?

Winter averaging is a billing method developed to give you the best possible break on sewer billing costs.

If you are eligible, this method takes the water consumption used in the winter quarter as the basis for billing sewer charges throughout the year. You will not be paying additional sewer charges for warm weather purposes such as watering lawns, washing cars, landscaping, gardening, or filling pools.

Treatment providers may not use this same method for their charges.

How Do I Enroll?

Eligible customers are automatically put on winter averaging after one year of consumption history. The eligibility requirements are:

• Residence must be a single family or two-family dwelling.
• The first meter reading of the quarter must be an actual reading.
• Residences with a second sprinkling meter are not eligible for winter averaging.
• A customer must have one full year of consumption history prior to the winter quarter.

What If I Do Not Want To Use Winter Averaging?

Most eligible customers are put on winter averaging automatically. If you ask to be removed from this billing method, you will be billed based on 100% of the water consumed each quarter.

It may be beneficial for you to decline the winter average option if you have high winter water consumption or low usage in the warmer weather.

You will remain on this 100% billing unless you submit a written request asking to be placed back on the winter average billing.
