Understanding Winter Sewer Averaging and Your Utility Bill
Questions About Sewer Charges on Utility Bills
The City of Smithville has recently received inquiries from residents regarding the sewer charges reflected on utility bills. Much of this relates to the City’s Winter Sewer Averaging program, which is used to calculate sewer billing for a portion of the year. The information below is intended to help clarify how sewer charges are determined and why the averaging process is used.
Understanding Winter Sewer Averaging and Your Utility Bill
As colder weather arrives and outdoor water use declines, Utility Billing begins implementing the Winter Sewer Averaging program, a seasonal billing method designed to more accurately reflect each household’s wastewater usage.
What Is Winter Sewer Averaging?
Winter Sewer Averaging is used to calculate sewer charges for most of the year (March through November). Instead of basing sewer charges on each month’s actual water usage during these warmer months, the City determines an average of the water used during December, January, and February.
That winter average is then applied to sewer bills beginning with the March usage cycle billed in April, and continuing through the November billing cycle. During the winter months themselves, sewer charges continue to be based on actual water consumption.
Why Is This Method Used?
Water used outdoors for activities such as lawn irrigation, pool filling, or vehicle washing typically does not enter the sanitary sewer system. Winter Sewer Averaging helps ensure residents are charged only for water likely to return to the sewer system, resulting in a fair and cost-effective billing structure.
How It Works
-
December–February: Sewer charges are based on actual monthly water usage.
-
March–November: Sewer charges are based on the average winter usage calculated from December, January, and February.
This approach may lower sewer costs for households that use more water outdoors during warmer months.
Opt-Out Option
Residents who prefer to have sewer charges calculated on actual monthly usage year-round may opt out of Winter Sewer Averaging. This may be beneficial if winter water consumption is unusually high due to leaks, visitors, or other temporary factors.

Tips for Residents
- Be mindful of water use during December through February, as it determines your averaged sewer billing for the remainder of the year.
- Consider how unique winter activities (such as filling a hot tub or construction-related water use) may affect your winter average.
- Review your utility bill regularly to monitor usage patterns.
