Garbage dump site

Hi I recently inherited a pickup truck. They bed is filled with old cat litter in bags and plastic totes. I'm wondering where in the Eau Claire area I could go to just pull out the whole plastic bed liner and cat litter.

I know in Whitehall they have a scale you drive on, unload your garbage then they weigh you again and you pay by weight. I was wondering if there is anywhere similar around Eau Claire.
