The volume of flow used for computing industrial waste surcharges shall be metered water consumption of the user as shown in the records of water meter readings maintained by the Engineer except as otherwise agreed to by the Engineer.
(a) If the user discharging industrial wastes into a sanitary sewerage system procures any part, or all, of this water from sources other than the City's water supply system, all or part of which is discharged into the sanitary sewerage system, the user shall install and maintain at his expense flow meters of a type approved by the Engineer for the purpose of determining the volume of water obtained from those other sources.
(b) The user discharging industrial wastes into a sanitary sewerage system may install and maintain at the user's expense metering devices for determining the volume of waste being discharged to the public sewer, from which the industrial waste surcharge would be computed. The measuring devices shall be of a type acceptable to the Engineer.
(c) The Engineer may require the installation of devices for measuring the volume of waste discharged if these volumes cannot otherwise be determined from the metered water consumption records.
(d) Any metering device for determining the volume of waste discharged to the sanitary sewerage system shall be installed owned and maintained by the user. Following approval and installation, such meters may not be removed without the consent of the Engineer.
(e) Users without source meters. For users where, in the opinion of the Engineer, it is unnecessary or impractical to install meters, the quantity of waste may be based upon a rational determination of the waste water discharged and may consider such factors as the number of fixtures, seating capacity, population equivalent, annual production of goods and services or such other determinants of water use necessary to estimate the waste water volume discharged if such method is not in conflict with appropriate State or Federal permit or grant conditions.
