Wis. Stat. § 66.0405
Cities, villages and towns may remove ashes, garbage, and rubbish from such classes of places in the city, village or town as the board or council directs. The removal may be from all of the places or from those whose owners or occupants desire the service. Districts may be created and removal provided for certain districts only, and different regulations may be applied to each removal district or class of property. The cost of removal may be funded by special assessment against the property served, by general tax upon the property of the respective districts, or by general tax upon the property of the city, village or town. If a city, village or town contracts for ash, garbage or rubbish removal service, it may contract with one or more service providers.
