If a user discharges wastes of unusual strength or character to the treatment facilities which cause or increase the operation and maintenance costs, he or she shall be ordered either to install pretreatment facilities or pay for the extra costs of treating the wastes. This decision will be made by the city, prior to the time the user begins to discharge extra strength wastes.
