The strength of sewage discharged into the public sewer shall be determined in one of the following ways at the option of the City:
(a) Sampling of Average Characteristics. Samples of the sewage discharge shall be taken at a sampling point provided by the property owner and acceptable to the City in accordance with this chapter and other regulations and rules promulgated by the City. Sufficient samplings shall be made to enable the determination of a reasonable average value for the quality and characteristics of the sewage discharge satisfactory to the City. Samplings and laboratory evaluation shall be made by the City in accordance with the current edition of "Standard Methods for Examination of Water and Waste Water," as published by the American Public Health Association, or regulations of the Pennsylvania Department of Environmental Resources. The average characteristics thus determined shall be used as the basis for extraordinary waste surcharge calculations. The City shall review such average characteristics as often as it deems necessary to maintain an average characteristic with reasonable accuracy.
(b) Sampling of Individual Characteristics. When, in the opinion of the City Engineer, a reasonable average sewage characteristic cannot be obtained as outlined in subsection (a) hereof, the installation of a device capable of automatic sampling may be required. Such device shall be of a type acceptable to the City, shall be installed in accordance with plans and specifications having prior City approval, shall be installed in a control manhole as required by ordinances of the City, and shall be installed, maintained and repaired by the owner at his or her expense. Sampling by means of this instrument shall be at a time and in a manner directed by the City Engineer in order to secure a reasonable and representative sample satisfactory to the City. The results of this sampling shall be used in the computation of surcharges.
