What Goes into Water Rates

Tacoma Water's residential rates vary inside and outside the Tacoma city limits. In each case, however, there is a monthly customer service charge based on the size of the water meter, plus a charge for the amount of water used.

Water use is measured in units of cubic feet (CCF). One unit is about 748 gallons of water. The cost per unit of water is determined by the time of year, amount used and where you live.  

Tacoma Water charges a higher rate for water use above five units from June 1 through September 30. This difference reflects the higher cost of providing water during the summer and is also designed to encourage water conservation. Learn how you can save water.
