Increases on water (6%), sewer (3.5%), and stormwater (5%) rates are to fund reliable, safe, and efficient utility operations and maintenance and to provide revenue for required utility improvements.

Sewer Usage Rate - Winter Average on Water Use
Winter Average is based on usage from 11/1/19 to 6/30/20 of the previous year.
To calculate the winter average on water use for sewer, add the 4 bi-monthly consumption usage amounts from your water meter readings on 12/31/19, 02/29/20, 04/30/20 and 06/30/20, divide the total by 4 bi-monthly billing periods = Winter average on sewer for 2021 (rounded up to the nearest whole number). The first 4 ccf are not billed for. NOTE: Your sewer charge will remain the same amount for the 6 bi-monthly billing cycles billed for usage from 01/01/2021 – 12/31/2021.
For those customers and/or accounts that were not established during the full winter averaging period, the city average on water usage will be assigned for this period until a full winter averaging period is established for the period of 11/01 – 06/30, per the Sanitary Sewer Ordinance No. 2328 under section 18.03.210 E - In special cases, single-family residents will be billed according to the following policies:
| Special Case | Sewer Rate Policy |
| New Homes | Billed at system average charge until use is established. |
| Changes in Property Ownership | Billed at system average charge until use is established. |
| Non-Water Customers | Billed at system average charge. |
| Leak Adjustments | Billed per adjusted winter volume. City will factor leak adjustment into calculation for sewer rate. |
