Wisconsin Statutes Municipalities (Ch. 59 to 68) § 62.18. Sewers

(1) Cities may construct. Cities shall have power to construct systems of sewerage, including a sewage disposal plant and all other appurtenances thereto, to make additions, alterations and repairs to such systems and plants, and when necessary abandon any existing system and build a new system, and to provide for the payment of the same by the city, by sewerage districts or by abutting property owners or by any combination of these methods. Whenever the council shall determine to lay sewers or provide sewerage in any portion of the city it shall so order by resolution which shall describe with reasonable particularity the district to be sewered. Whenever the territory of any city of this state shall be adjacent to or border on the territory of any other state, such city shall have power to build or construct a sewage disposal plant in such adjacent state, either alone for its sole use or jointly with some city or municipality in such adjacent state for their joint use on terms to be agreed upon by such municipalities. And if either city or municipality shall build or construct a sewage disposal plant, the city in this state may contract with the other city or municipality for its joint use on terms to be agreed upon.

(13) Sewers, where laid. Any contractor or other person acting under the direction of the board of public works may lay sewers in and through any alleys and streets, and through any breakwater into any lake and also in any highways of the county, whether within the limits of said city or not; such contractor shall repair such streets, alleys, breakwaters and highways and restore the same to their former condition upon the completion of such sewers.
