(A) If any customer who discharges sewage or industrial waste into the sewerage system, either directly or indirectly, obtains part or all of the water used therein from sources other than the city and the water so obtained is not measured by a meter in a manner which is acceptable to the city, then in such case, the city shall permit the discharge of sewage or industrial waste into its sewerage system only when the customer shall, at his or her own expense, install and maintain a water meter and/or a flow meter which shall be satisfactory to the city. Such recorders shall be installed so as to either measure all water received on the premises of the customer or all effluent therefrom as established by ordinance, and the charges and rates shall be applied as established therein.
(B) Any customer who shall discharge sewage or industrial waste into the sewerage system which shall be deemed deleterious to said sewerage system or sewage treatment process may be required to pre-treat such waste to an acceptable standard as defined by ordinance.
(C) The city may require that any customer who shall discharge industrial waste into the sewerage system of the city shall install flow meters, sewage sampling equipment such as, but not limited to, monitoring devices, as it may deem necessary for purposes for a periodic review of rate structures, or such other purpose as may be advantageous to the city.
(D) Whenever any customer discharges industrial waste sewage into the sewer system which does not meet the established requirements for industrial waste, the city may terminate service to said customers. However, the City of Mankato reserves the right to exclude any or all industrial wastes, regardless of strength.
(E) Any new connection(s) to the sanitary sewer system shall be prohibited unless sufficient capacity is available in all downstream facilities including, but not limited to capacity for flow, CBOD5, total phosphorus and suspended solids, as determined by the Superintendent.
(F) Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such building drain shall be lifted by an approved means and discharged to the building sewer.
(G) Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, any flammable wastes, sand or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of the type to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors, the owner(s) shall be responsible for the proper removal and disposal of the captured materials by appropriate means, and shall maintain a record of dates and means of disposal which are subject to review by the Superintendent. Any removal and hauling of the collecting materials not performed by the owner's personnel must be performed by a currently licensed waste disposal firm.
(H) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this subchapter shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association. Sampling methods, location, times, duration and frequencies are to be determined on an individual basis subject to approval by the Superintendent.
