Utility Rates
2023 Utility Rates
Water, sewer, and stormwater utility rates are increasing in 2023. Water, sewer, and stormwater utility rates are assessed on an annual basis. Rate increases fund maintenance, operations, and required utility improvements to provide you with safe, reliable, and efficient water, sewer, and stormwater utilities. Several major factors influenced the 2023 rates, including financing for projects included in the planned 2023 - 2029 Capital Facilities Plan (CFP) update, the COVID-19 pandemic, inflation, and wastewater treatment and water purchase prices.
Water and sewer rates
Water rate increases (6%) and sewer rate increases (2.5%) are specific to City of Bothell Water/Sewer customers. There are multiple water and sewer districts within the City of Bothell and immediate vicinity. Find your utility provider. Water and sewer rate increases appear on each of the six bi-monthly billing statements each calendar year.
Stormwater rates
Stormwater rate increases (6%) impact anyone within city limits. Stormwater rate increases appear on semi-annual King and Snohomish County property tax billings.

Sewer Usage Rate - Winter Average on Water Use
Winter Average is based on usage from 11/01/21 to 4/30/22 of the previous year.
To calculate the winter average on water use for sewer, add the 3 bi-monthly consumption usage amounts from your water meter readings on 12/31/21, 2/28/22, and 4/30/22, divide the total by 3 bi-monthly billing periods = Winter average on sewer for 2023 (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 1/01/2023 – 12/31/2023.
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 – 4/30, per the Sanitary Sewer Ordinance No. 2364 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. |
