(a) The incorporation or annexation of territory within the town sanitary district detaches that territory from the district.(b) The city or village and the town sanitary district are subject to pars.

The territory is served by the town sanitary district with a water or sewerage system; or2.

Any water or sewerage system, including all mains and all property of the system, shall belong to and be operated by the district or the city or village, in whichever the major portion of the patrons reside on the date of annexation or incorporation, unless other provision is made by agreement of the governing body of the city or village and the commission. Express power is hereby granted to the governing body of the city or village and the commission to contract with each other relative to the operation and property of any water or sewerage system.2. In determining the major portion of the patrons, each location served shall be considered as one patron irrespective of the manner in which the title to the property is held.(dm) If the responsibility for continuing the operation is vested in the town sanitary district, it shall continue, except by agreement, until the proportion of users changes so that a majority of the patrons reside in the city or village, at which time the property and the responsibility shall shift to the city or village.(e) Any special assessment levied before the incorporation or annexation shall continue to be collected by the district or city or village which is operating the water or sewerage system and shall be applied to the purpose for which the original assessment was made.(3) SERVICE AREA.

Sub. (2) (b) requires selective rather than automatic application of sub. (2) (c) to (e). Town of Hallie v. City of Eau Claire, 173 Wis. 2d 450, 496 N.W.2d 656 (Ct. App. 1992). Sub. (2) (d) is inapplicable to annexed property that contains no commercial or personal patrons of a town water system that runs through it. Under sub. (1), the annexed property lies within the annexing city's domain as a matter of law and the city bears the responsibility of providing water. Town of Sheboygan v. City of Sheboygan, 203 Wis. 2d 274, 553 N.W.2d 275 (Ct. App. 1996), 95-1839. Although sub. (1) expressly precludes a sanitary district from taking any action to challenge an annexation when its entire territory has been subsumed by an annexation, the fact that sub. (2) is silent on such challenges does not require that sub. (2) must be interpreted to permit such challenges when only a partial taking of a sanitary district's territory has occurred.
