Sumner residents will soon be paying more for their garbage pickup due to the annual adjustment based on the Consumer Price Index of the Seattle-Tacoma area.

The city contracts with D.M. Disposal for waste collection and each year the U.S. Bureau of Labor Statistics evaluates the Consumer Price Index, which is the average change over a period of time of prices consumers pay over time for goods and services.

The city’s contract with the disposal company requires an adjustment each year of 80 percent of the Consumer Price Index change.

Derek Barry at the city of Sumner Public Works Department said the most common change in the price of waste pickup is the roadside trash price increase, which is now $19.36 each month, up from $18.35 each month.
