Homeowner wastewater rates are based on the amount of fresh water a household uses during the most recent four-month winter billing cycle, typically December through March, when water usage should be at its lowest. This eliminates any extra water used in summer gardening and yard maintenance, which doesn't end up in the wastewater treatment system.
New customers are charged based on average residential use. A typical single family home in Tacoma uses 600 cubic feet, or 6 ccf, of water each month during the winter months. Once a customer establishes a winter water usage history, their monthly rates will be adjusted accordingly.
