Monthly Residential Utility Rates

Single family residential homes located within City limits are billed monthly for water, sewer, LOTT, and stormwater services.   

Understanding Your Statement 

Water charges consist of two parts: 

  • Base Fee - This flat rate, sometimes called the "ready to serve" fee, is billed every month regardless of the quantity of water used. This fee covers operational costs the utility incurs, like water quality monitoring, treatments, and meter reads. 
  • Consumption Fee - Consumption fees are structured in a four tier system to allow accounts to be billed for the amount of water that is used. Higher usage of water is billed at a higher rate than those with lower water usage. Conserve water and save on your monthly water bill!

All fees are subject to a 6% utility tax that is reflected on the monthly statement.

Please contact the Utility Billing division at (360) 754-4133 if you need help understanding your bill or if you are concerned that you may have a leak.
