Bonney Lake residents should prepare for a small bump in their garbage rates this spring.

Last week, the city announced a 5.7 percent increase in collection rates for residents and businesses.

The increase – which is higher than it has been in the last three years – is part of the city’s five-year contract with DM Disposal, said the city’s Facilities and Special Projects Manager Gary Leaf.

“The last three years of that contract, there was a rate freeze,” he said. “The only rate increases were for the dumping fees.”

Roughly half of the rate increase covers an increase in the cost of living (a 5.2 increase in the Consumer Price Index), while the other half covers a rise in dumping fees, since the Pierce County Council approved a 5 percent increase in its per-ton landfill dumping fee last November.

Beginning in March, residential customers will see between a one to three dollar difference per bin in their monthly garbage bills, depending on the size of their garbage bin.

Those who use a 10, 20 or 32 gallon bin will pay around a dollar more on their bills, give or take.

Residents who use a 64 gallon bin will be charged around two dollars more, and those who use a 96 gallon bin around three dollars more.

Yard waste services are also rising, from $6.09 a month to $6.41.

These rate increases do not include the 3.6 percent state refuse collection tax that is applied to these rate increases
