2026 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!

Water, sewer, and stormwater services currently are subject to a 12% utility tax that is reflected on the monthly statement.

Below is an example of the monthly charges for a single family residential home with no water consumption compared to a home that used 800 cubic feet (CF) of water, both with a 3/4" meter. Please note: On an actual bill, the base and consumption fees are combined.

2026 Monthly Multi-Family Utility Rates

Multi-family units located within city limits are billed monthly for water, sewer, LOTT, and stormwater services. Sewer, LOTT, and stormwater fees are based on number of units whereas water is billed for consumption.

All the fees below are subject to a 12% utility tax that is reflected on the monthly statement.

• Base fee - This flat rate based on meter size, 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. During the summer months when the irrigation season is upon us, accounts tend to be billed at a higher rate for larger amounts of water used.

Property owners are responsible for all water that passes through the meter onto the property. Do not tamper with a water meter as they belong to the city. Any damage that might occur due to tampering could lead to additional charges. Meters are read at the beginning of each month and are billed at the end of the month. Please contact the Utility Billing staff at (360) 754-4133 if you need help understanding your bill or if you are concerned that you may have a leak.
