(a) All measurements, tests or analyses of the characteristics of waters and wastes to which reference is made in the current edition of Standard Methods for the Examination of Water and Waste Water, published by the American Public Health Association, shall be determined at the control manhole provided or upon suitable samples taken at such control manhole provided or upon suitable samples taken at such control manhole. If no special manhole has been required, the control manhole shall be considered to be a downstream manhole in the public sewer nearest to the point at which the building sewer is connected. Sampling shall be carried out by methods customarily accepted to reflect to effect of constituents upon the sewerage facilities and to determine the existence of hazards to life, health and property. The particular application involved will determine whether a twenty-our hour composite of the discharge is appropriate or whether a grab sample should be taken. In most cases, biochemical oxygen demand and suspended solids analyses are obtained from twenty-four hour composites of the discharge, and pH is determined from periodic grab samples.
(b) A monthly report of the quantity and characteristics of any industrial waste discharged into the sanitary sewer shall be presented to the Sanitary Engineer by the owner no later than the fifteenth day of the month following the reporting period.
(c) It is not the intent of any statement contained herein to prevent any special agreement between the Municipality and any consumer of the sanitary sewerage system who discharges a waste of unusual strength or character and subject to special payment to the Municipality by such consumer for the treatment of such waste and whose payment is proportionate to costs consistent with rates determined by the Miami Conservancy District.
