§ 51.112 COMPUTATION OF SEWER RENTALS OR CHARGES.
   (A)   Flat rates for domestic consumer units and schools. Sewer rentals or charges for sanitary sewage discharged into the sewer system from any improved property constituting a domestic consumer unit or school shall be in an amount as established from time to time by resolution of Borough Council.
   (B)   Metered rates for commercial, industrial and institutional establishments.
      (1)   Sewer rentals or charges for sanitary sewage and industrial wastes not subject to special charge hereunder which shall be discharged into the sewer system from any improved property constituting a commercial, industrial or institutional establishment, other than a school, shall be based upon a volume of water usage, adjusted, if appropriate, as provided in §§ 51.110 through 51.121, where the volume of water usage shall be metered in connection with the water system or otherwise.
      (2)   Sewer rentals or charges for sanitary sewage and industrial wastes not subject to a special charge hereunder which shall be discharged into the sewer system from any improved property constituting a commercial, industrial or institutional establishment, other than a school, may be based upon actual metered volume of a discharge, as permitted in §§ 51.110 through 51.121. In either of the foregoing cases, such sewer rentals or charges shall be in an amount as established from time to time by resolution of Borough Council.
   (C)   Nonmetered rates for commercial, industrial and institutional establishments. Sewer rentals or charges for sanitary sewage and industrial wastes not subject to a special charge hereunder which shall be discharged into the sewer system from any improved property constituting a commercial, industrial or institutional establishment, other than a school, when the volume of water usage shall not be metered in connection with the water system or otherwise, and when the actual volume of discharge shall not be metered as permitted in the subchapter, shall be computed in accordance with the metered rate schedule provided herein and shall be based upon an estimate by this borough of the water consumption of said improved property constituting a commercial, industrial or institutional establishment, other than a school.
   (D)   Multiple users. Each billing unit located in a multiple unit shall be billed as a separate entity and the foregoing sewer rentals or charges, as appropriate, shall be used in computing the sewer rentals or charges applicable to each such billing unit as though such billing unit was in a separate structure and had a direct and separate connection to the sewer system.
   (E)   Charges for industrial wastes having certain concentrations.
      (1)   Charges will be made for all waste, in the event this borough consents to accept industrial wastes for discharge into the sewer system from any industrial establishment having total suspended solids and BOD in excess of the following concentrations:
 
Suspended solids
300 ppm
BOD
250 ppm
 
      (2)   The total charge for the total volume of waste having concentrations in excess of the foregoing shall be determined in accordance with the following formula:
 
Total charge = Q + [0.001 Q (B)D in ppm - 250)] +
[0.001 Q (SS in ppm - 300)], with
Q meaning “metered quantity charge” under §§ 51.110 through 51.121 and
with SS meaning “suspended solids”
 
      (3)   The strength of industrial wastes shall be determined at intervals deemed advisable by this borough or as may be requested by the industry. The collection and analysis of waste samples for determination shall be supervised by a registered professional engineer approved by this borough. All costs for water sampling and collection shall be paid by the party which desires that the waste be sampled and analyzed. The analysis of all waste samples collected shall be made in accordance with the latest edition of Standard Methods of the Examination of Water and Sewage, as published by the American Public Health Association.
   (F)   Changes in flat rate classifications. If the use or classification of any improved property shall change during any quarter annum period, the sewer rental or charge shall be adjusted by this borough, by proration on a monthly basis to the nearest calendar month, with a credit or charge, as shall be appropriate under the circumstances, being made on the statement for the next succeeding quarter annum period.
   (G)   Additional flat rate classifications and modifications of flat rate classifications. This borough reserves the right, from time to time, to establish additional flat rate classifications and to establish quarter annum rates therefor; and this borough reserves the right, from time to time, to alter, modify, revise and/or amend flat rate classifications and the quarter annum rates applicable thereto.
   (H)   Special agreements. Notwithstanding any provision in this §§ 51.110 through 51.121 to the contrary, this borough shall have the right, based upon good reasons and circumstances existing, to enter into special agreements with the owner of any improved property, which improved property shall constitute an industrial establishment, with respect to terms and conditions upon which sanitary sewage and/or industrial wastes may be discharged into the sewer system and with respect to payments to be made to this borough in connection therewith. In such event, such service and payments with respect thereto shall be governed by terms and conditions of such special agreement. This provision shall apply specifically with respect to Alcoa.
