Sec. 12754.

When the structure in which sanitary sewage originates is not connected to an available public sanitary sewer system within the time specified in section 12753, the governmental unit in which the structure lies shall require the connection to be made immediately after notice, which may be by first class or certified mail to the owner of the property or by posting on the property.

The notice shall give the approximate location of the public sanitary sewer system which is available for connection of the structure involved and shall advise the owner of the requirements and enforcement provisions of sections 12752 to 12758 and any applicable ordinance or regulation.

Where a structure in which sanitary sewage originates is not connected to an available public sanitary sewer system within 90 days after the date of mailing or posting of the written notice, the governmental unit which operates the available sanitary sewer system may bring an action for a mandatory injunction or order in the district, municipal, or circuit court in the county in which the structure is situated to compel the owner to connect to the available sanitary sewer system immediately. The governmental unit may join any number of owners of structures situated within the governmental unit in the action to compel each owner to connect to an available sanitary sewer system immediately.
