Nothing within this subchapter shall be interpreted to require the city to provide sewer service at published rates when an owner deposits prohibited waste in the sewage system or causes a higher than normal expense in the operation of the system or higher than normal charges from the City of Winona for the treatment or conveyance of the wastes. Nothing in this subchapter shall be interpreted to prohibit the city from the handling of deleterious wastes, pretreatments or setting a charge higher than the published rates on an agreement basis. The agreement shall be made by the city and the owner after considering, but not limited to, the problems in handling the effect on the sewage system and the cost of handling the waste.
