(A) Where required, in the opinion of the approving authority, to modify or eliminate wastes that are harmful to the structures, processes or operation of the wastewater treatment facilities, the person shall provide, at his or her expense, such preliminary treatment or processing facilities as may be determined necessary to render his or her wastes acceptable for admission to the public sewers.
(B) (1) Where discharge of such wastes to the sanitary sewer are not properly pretreated or otherwise modified, the approving authority may:
(a) Reject the wastes or terminate the service of water and/or sanitary sewer;
(b) Require control of the quantities and rates of discharge of such wastes; or
(c) Require payment of surcharges for excessive cost for treatment; provided, such wastes are amenable to treatment by the normal wastewater treatment facilities operated by the city.
(2) The amount of surcharge shall be computed as twice the actual incremental costs (above normal costs for labor, power, chemicals, equipment rental, mileage and the like) experienced by the city for handling the improperly pretreated wastewater. See §§ 50.28 and 50.29 of this chapter and Ch. 35 of this code of ordinances for method of computing normal industrial waste charges.
